well currently i have a GTR fuel pump in my 32 and its time to upgrade (nothing is currently wrong with the GTR pump but will run out of puff with new mods) I was simply going to put the 044 intank and be done with it but after talking to a few people i learned that you can leave that pump intank as a lift pump and mount the 044 externally. I've had a good think about this and the more i think about it i think it would be a really good idea but i'm not too sure exaclty where to mount the 044 as i don't want/have a surge tank! Was also thinking this would be easier than mounting the 044 intank (quite a bit of modding needed)

If anyone has done this and has pics it would also be much appreciated!

cheers!

Mount it where ever it fits.

internally (inside boot) or externally (underside of the rear of the car)

Its upto you where you put it.

Most people going to the effort of installing a secondard inline fuel pump would have surge tanks IMO.

Going to all the effort there is no point not to.

So hence probably not a lot of people have two pumps for mild power applications

Here’s the problem, most guys find that installing a second pump is not as easy as it sounds. You have to;

1. find space for it

2. mount it in rubber as they vibrate a lot

3. run the fuel lines to it

4. run a separate relay, as 2 pumps draw too much current for the standard wiring

5. run a decent size power supply from the battery to the pump

Compared to, remove the standard pump and make a few small mods and install the 044. Later on, if you need the extra flow that 13.8 volts gives you, you can run the relay and dedicated power supply.

That’s the reason most people do the pump swap, it is actually easier/faster/simpler.

>_< cheers :(

ok just pulled my old pump out and realised that GTR and GTS have different set ups

looks like its going to be a shit load easier to fit it in tank than i expected

what will happen if i dont install a check valve?

The check valve stops fuel flowing back to the tank when the pump is off.

So when you turn your car off basically you'll lose fuel pressure, the longer it's

off the more pressure you lose.

In real terms this means when turning it back on after it being off overnight

you might need to wait a few seconds between switching the pump on and

engaging the starter motor.

I'd leave the check-valve on there :P

044 do not come with a check valve

either way im off to buy one now :wave:

mine came with a banjo style fitting with a check valve... i removed it and installed one from motorsport connections ..

lets you use a straight fitting Vs the banjo style side exit off the pump.. also lets you use a speedflow type screw on fitting for your main feed line from the pump...

plus it screws directly into the fitting on the end of the pump as well

think it was about $50

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
