Fuel Pump Upgrade

hey guys :)

i own a 93 R32 gts-t.

i've been reading up on people's opinions on fuel pump upgrades for most skylines, and bosch and walbro seem to be the main pumps being used.

only thing i'm worried about is if i end up going under 1/3 of a tank, and the car leans out.

it seems my fuel pump is starting to die on me and it's time to upgrade, but i'm not really sure on what to buy.

i've been told to get a gtr pump, but i don't like the whole concept of putting a 14 year old pump into my car.

i don't want to spend a big amount of money for a simple upgrade, since i'm not running any high dependancy mods at the moment.

so what's your opinions?

what does it cost for fuel pump rebuilds?

what's your experiences with the above mentioned pumps?

:(

It just so happens I am in the same boat. I have a 92 R32 GTR. Pump is on the fritz. When under load (on the throttle) the car starts to stagger a little (definately gasping for fuel). I have decided on a Walboro outfit. I wanted to keep it in tank and not set up an external, that is why I went for Walboro. Bosch do have the in tank jobbies but I would basically be replacing the stock one for one of about the same size. The Walboro pump I am getting is good for 700hp and flows 300Ltrs/min and is setting me back around $260. As I will be upgrading the engine quite considerably I figured I may as well get the pump now. Once I have fitted it the Power FC goes in and then tuned and so on and so forth.

I would forget the walbro, and the bosch. get a nismo pump. they fit directly into the tank mounts and are mounted exactly as the stock one was so there are no problems with fuel surge. they have plug already fitted to wire straight in, and they flow heaps. also they are super reliable which I cannot say the same for the bosch and walbro pumps. yes they cost more, but a fuel pump is pretty much the most critical part of a high pressure EFI system.

If you install the walbro and bosch pumps correctly then you will not have the 1/3 tank problem. I have had the experience of both walbro and bosch pump in my 93 gtst and have driven my car 50km after the fuel light has come on and did not run out of fuel.

      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!

      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.
