I agree about cutting off the tabs. I do that too.

You can use hose clamps mate. I have 2 hose clamps on the pump in my car.

I'm pretty sure that the wire on the side of the pump isn't for dual stage. It is just a ground. The reason I know this, is 32,33 and 34 pumps all have that extra side ground.

I didn't install the side ground for my car, and I do get the 2 stage. On idle, it's soft. If I blip the throttle, it goes louder.

Cheers

Well Ive been having issues.

The gtr pump is a bit of a fiddle to get into the GTST.

You have to be careful with how your rotate the body of the pump. The GTR pump has a piece at the top (not sure what it is) Maybe a relief valve or something.

This fouls on the tank if rotated incorrectly.

See fouling on pic..pump couldn't go all the way down

Also when you take the sock off the GTST pump you cant use the post and lock washer as you need to rotate it to the same orientation.

Chris did you find the same problem? When you push it on hard it seems to hold pretty tight. Hopefully this is ok.

OLD PUMP

I still haven't been able to test it as I need a new tank seal as mine is rooted.

So for me it wasn't a 2 hour job :D

NEW/2nd hand GTR PUMP

Mine was different again. the R34GTR pump is fatter, cased in Rubber and is Black in color. Im also having issues, As also I cannot get it all the way down. AS the pumps casing has also its own Hose clamp on it. which is in a position that it fouls the side of the tank also, and I cannot just turn the clamp around as the clamp has 2 teeth on the far side of the clamp which earths to the middle of the pump. Wondering if i should just remove the pumps casing clamp altogether, but this earth will no longer attach..

Mine didnt have that Weird thing on top of the pump near the Terminals like yours does ben.

hang on ben. I'm a bit confused. did you cut the bottom of your bracket off?

When I installed my gtr pump, you know that metal pipe up the top? I had to cut that up (so I used to next nipple to clamp the hose). The pump was significantly taller.

that way, I could still have the pump sitting on rubber, sitting on that bottom part of the bracket. That's why I was asking if you had cut the bottom off yours

Yeah I cut the bottom of the bracket off.

When you rotate the body of the pump so that the sock will angle the correct way the bit at the top fouls on the tank. SO I rotated the pump so it doesnt foul but then I can't use the locating post for the sock.

Was wondering how you did yours.

I cut some of the pipe you are talking about also.. so that it sat on the next bead..

Well I got it all the way down now. My +ve terminal is next to the bracket I think. When you swapped over the sock it would be the wrong orientation if you used the locating post..did you just push it on as tight as possible and not use the locating post and locking star washer?

Edited by benl1981

I have mine attached still using the bottom part of the bracket. For me, cutting the top pipe was enough. I have the sock clipped on.

I did it when the tank was full, so couldn't see how far down it went, but it felt the same as when i had taken it out.

Are you sure it's not all the way down? is that how it was when you took it out? if it's fouling, give the bracket a bit of a bend.

Well I guess that makes sense then. Do you have problems with when you get really low on fuel i.e. it not picking up the last 5-10 litres?

Oh, you didn't use the post either is that what you mean?

I don't see it as a major problem but thought maybe I hadn't lined something up right.

Haha, ok, what i did, is you could say the sock faces the wrong way. i did use the clip. Basically, the sock still points down, just slightly backwards. When I stuck it down into the tank, it still sticks down to the lower part of the tank anyways. No problem with low fuel (having said that, I normally fill up at about a quarter tank - I don't go down to the empty light. but even the empty line is fine on my car).

If you want the sock the right way, and use the clip, you could just bend the bracket out slightly, or space the pump out a bit with some efi hose. From the looks of your thing, even a couple mm would help it clear. But I don't think it'll come off even without the clip.

I can't believe that you cut the bottom of your backet off. There's enough room after you just trim the top barb back a bit. lol. I like that part, because from a mechanical point of view, imo, it would stop the pump sliding down. If I was you, I'd add another hose clamp on (yes I know it's clamped to the hose above). Like I said, I like things perfect, and i am anal.

Well if you leave the bottom piece for the pump to still sit on it it has to be spaced out from the main assembly that I was hose clamping it to. So I just chopped the bugger off.

1 hose clamp will do..as you say the hoses are holding it and the clamp. There is no real load on it. Maybe some vibration from the unit but 2 is overkill. 1 in the middle of the 2 ridges on the pump is good for me...

My tank seal was a bit split and when I tried to put it back in its become all mangled. The petrol has deteriorated it and made it all tacky etc. the car is almost 14 years old now!! And I'm going to be pushing it to make as much power or more than a new 6L v8 hahah

    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers)
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
