Awesome - Got a dyno done on my car and the AFR stays at like 14ish from 1k rpm to 6k rpm >_<

So been taking it easy and saving for a fuel pump but it's hard when you just get your annual insurance bill... anyway I think I might go for this tomei pump too looks/sounds better then the others I have heard about.

Had a read through this and I think I can install it myself - well done guys and thanks!

yes easy to fit.. so I thought.. I can hear the pump (nismo) priming (or trying to) but it's bloody loud and doesn't sound right, sounds far to high pitched or something. Car doesn't start, so I assume it's not feeding fuel, but when I disconnected the hoses again after a little while the line was full of fuel. Disconnecting the line going back to the pump released a lot of air (from the tank I think).

Any one have any ideas? Could I just have the hoses connected the wrong way around or something? If that even matters.

Well i installed my walbro today (from sliding performance) anyway had a bit of trouble with the fuel pump isolator rubber that goes on the bottom, its to small to hold the pump in place on the standard bracket, so i modified the standard one by cutting it to fit the fuel pump as best i could, it sits slightly adjar bcoz of the filter sock that comes with this pump doesnt go down where the standard one goes it goes out to the side instead. i just want to know with this not being as deep as the standard one will i have trouble with fuel pick up etc?

also i zip tied the pump into place to stop it from moving. so it shouldnt slip off the bracket at all now. sounds a bit dodgey but we made sure it was sitting as close to stock as possible.

other then these problems it was all pretty straight forward.

id like to hear a few more story's of people who have installed walbro pumps to see if they had any problems with there installs?

Cheers

I did the walbro pump install, mine fitted fine with the smaller rubber bottom it came with. And the factory filter fits onto the walbro pump so you don't have fuel pick up problems when running low on gas. I found the walbro pump to be a very easy replacement.

the small rubber bottom i got doesnt fit tight like the standard one, the half round shape it fits into wasnt the same size on mine. so i just modified the standard one, seems to work just as good anyway, had no problems with it. pumps fine.

I installed Walbro, just had a good look at how std pump sat on bracket and then put Walbro in same place (slightly slower on bracket) using the rubber/foam sleeve it came with and 2 x steel threaded clamps (big hose clamps), used the filter sock from the std pump I think.

Changed it with fuel guage needle on empty line - started fine (on 2nd key turn) and hasn't missed a beat since, and I like to run to fuel light. (Yep change fuel filters regularly)

You can hear the pump if you listen for it and can hear the pitch change from idle voltage to on throttle voltage, certainly not an isue though, nice to know it's working.

FWIW: Nowhere near as loud as Bosch GTR pump in 200SX.

(If you use a Walbro they are very sensitive to voltage vs flow rate) there is a graph somwhere about fuel pump comparison for a Supra (US site), google it.

After reading the whole thread from page 1 to page 3, i can assume that the Nismo Fuel pump (which is identical to the Tomei one) WILL work with the stock Fuel regulator AND Stock injectors AND i do not need to install the included pressure valve .

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
