Fuel Pump

[dmonic1]

hi guys i got my fuel pump and pressure reg delivered today. something else came in the box which im not quite sure about. it came in a genuine nissan box and has "A VALVE CUT" on it. i am yet to pull my pump out so im not sure where it goes or what it does. it is in the picture on the bottom right.

Not positive but could be the fuel valve (in red on pic) , fits on the pump outlet hose inside the tank, you should see it when you pull your old on out. What did you buy and from where ? looks like a Skyline pump assembly.

cheers chook i thought i would see it once i pulled mine out. its a tomei pump for a 34 skyline. should be the same set up in the stag shouldnt it

itds a bypass valve incase you have a blockage in your fuel line so it doesnt kill your pump or burst a rubber fuel line. the fuel will exit here back into the tank safely. but youll have no fuel

completely different, although basic pump may be the same, which is all you needed, wiring is also diffferent. may be a challenge.

I ended up getting a SARD universal, direct drop-in replacement for the Stagea pump

well positive and negative is all the same regardless with wiring so that wont be hard to overcome shoudln't be to hard to get the pump into the stag bracket. so with any luck i will make it work. cant complain for $300 all up.

I agree, anything can be made to fit, best of luck, great price too.

hey chook, i to have the sard fuel pump but i had some problems with its dual flow rates..the idol flow rate makes the stag have a flat spot on takking off from a standing start.. did u have this problem? the auto spark is going to earth the pump so it runs at 100 percent all the time

[chook]

No, never had this problem, sure its the pump, not regulator/filter ? mine is the 165l/hr, maybe the larger ones dont handle the lower voltage ?

Hi guys, anyone installed a Walbro GSS342? It's 255LPH/500hp pretty similar spec's to bosch 040, and is also an in-tank pump... workshop recommended them over the Bosch; apparently the feedback they have had is that they are quieter than the 040 and very easy to fit. Just wondering if anyone's fitted one themselves to a series 2 stagea? How easy is it?

[RubyRS4]

Sorry for waking up an old thread, but if you're fitting a 040 pump how much do you fuel-proof the wiring to the pump? Are the rubber boots enough. I notice the stock pump has the plugs, but no real protection against the fuel.

?

Did you find out anything in the end Ruby? I just got a 040 replacement for my 12-month-old Walbro (which died ) and could do with some advice on how to get it into the bracket - it's frickin huge compared to the GSS-342 Walbro!

there is a photo on here somewhere of a 040 mounted on a stagea bracket . yeah its big but it fits well. i am not a fan of wallbros really . if something is smaller then it is doing more work and going to wear faster than something twice the size doing the same amount of work . and it would be twice as hard to make to the same standard so it should cost twice as much but it doesnt so yeah .

Hey that's interesting, thanks Lachlan. Didn't find that one! Just what I was after.

However ditching the cradle completely like that means no direct supply of fuel to the pump when the inch or two that's left in the bottom of the tank runs away during a corner... and I thought that pump had been designed to mount vertically? The pickup covers the whole end; so as the fuel level begins to drop a lot of it will become exposed...

Sold my 040 now but having a fuel pump die on you is still a little concerning... had a bit of a hassle starting it again tonight, after only about its 3rd real run since changing the pump. Not sure if it was still bleeding air out or I had bad fuel or what.
