Hello,

Sorry for the plain question, but ->

I'm about to replace my fuel pump ..

I was wondering how the fuel pump+cradle is actually mounted to the chasis.

From looking at the manual it seems there are no bolts that attach the pump assembly

to the car (fuel tank) ?

It must be secured somehow .. musn't it?

The top of the fuel pump cradle slides down onto a bracket that is mounted just inside the fuel tank. It's quite hard to explain, but if you open up the lid of your fuel tank, you'll see what I mean. To remove, you have to slide the cradle up and off the bracket. It's fairly self explanatory and easy, the job is just a bitch because it requires small arms and contortionist like flexibility. Probably not that bad if you're just replacing stock for stock, but upgrading to a bigger pump has some fun trial and error to go with it.

Hi there,

Many thanks!

Yes, I thought so (I mean that there is a bracket) ..

So the cradle just slides on it, and nothing to secure it (like a bolt or clip?)

I have a Tomei-Pump which is supposed to be a drop in and forget, so that will be (hopefully) painless.

I also need to pull the fuse off the pump and then let the engine idle till the fuel pressure has dropped, right?

?

Nothing to secure it...it relies on gravity, plus it slides a fair way down on the bracket, so it is fairly secure. In fact, when I put in my Bosch 040, I could only slide the top of the cradle half way down the bracket and it's still secure.

Don't know about the removing of fuses and engine stalling...I did mine without all this...shouldn't be any pressure after you've had the engine off for more than a few minutes.

days later I had fuel squirting everywhere lol just cover it up with a old towel when you remove the lines.

Oh ok...maybe changes in air temperature pressurised your fuel over time :P

There was seriously very little, if any, fuel that came out when I disconnected the lines...so I don't know what's going on there lol.

just put a nismo in my 33gtst, very easy, probably took 15 minutes of dicking around just trying to get it back on the cradle though. replaced a bosch 040 that i just couldnt get back on, and i easily spent over an hour on it and gave up.

Just put a torch in the tank when you've removed it and you will see how easy it actually is to put on

Hi ...

How do I remove the fuel lines (the 2 with the quick fit connector)

How does the connector work? (sorry, never seen these before)

Also did you use a hammer to remove loosen the big plastic nut?

(I would make a tool for this, but don't have the time at the moment ..)

Thanks!

i just used pliers to squeeze clamps together then pulled the hose off. although i had trouble with the feed line and ended up replacing it with new line, only because the feed line had no extra slack in it, i think it was about 63cm long so i just got 70cm worth.

i just used a big flathead screwdriver and a hammer to get it off

The top 2 hoses are return and the bottom one is the feed. Is that what you meant by connector thing?

or the wire connector? its just acts like a connecting point with wires both side

Hi there,

Thanks for the pictures and advice :)

I have attached a pictures of the hoses, I hope that makes it clearer.

(I have a Spec2, so I guess that's why I have these)

Hello there,

Just wanted to report that I recently changed the pump to a Tomei.

It all went alright, and the hardest part was probably fitting the fuel pump back in.

This was due to my big hand and the limited space in the tank.

Also I should have emptied the fuel tank more; I got quite dizzy from the fumes and my skin being

washed in fuel.

:)

Sorry I’m new here.     I am having a shocking time trying to work out the pump cradle mounting.   As it wasn’t mounted when I removed it

Well I hope you have a low fuel level because as a first timer it helps you to see what you need to do.

The cradle is a longish flat looking bracket that slides into and then clip locates in a plastic holder on the front of the tank.

Have a look, stand back and use an LED torch [try to avoid arcs and sparks] and see if you can see and feel the plastic holder.

Once you do you will sort of realise how the bracket slides down and then clips in place.

There is probably a tutorial in the How To section on this forum that will help, and good ole YouTube is always a 'go to'.

Maybe this:

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
