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

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
