Fuel Probs

[GimpyDammit]

Got my power fc tuned last night by Guiltoy,

Seems to run out of fuel at high rpm, he thinks its the fuel pump.

So question is, what fuel pump should i get for a mildly tuned 32 Gtr?

He recomended a Bosch 040, and i've seen Walbro 500hp in-tank pumps for $195 on sau.

Any experience or insight would be appreciated

They are both good as are the Nismo ones.

Bosch pumps are far superior to walbro.

Guilt-tripper told you Bosch, you trust him with your tune...so trust his advice on fuel pumps too.

The Bosch item is about $40 more...people who skimp on products are always the ones who scream the loudest when it goes 'pop'.

Its your fuel system...its keeping your engine alive...stick your hand in your pocket and put in a decent pump.

BTW...my 1000hp GTR uses an 040 as a lift pump.

Get a Bosch 044 and get it installed properly. Then it will be an intake pump And will run more HP than 040

if its a 300kw car an 040 would be better as all the 044 will do is cycle more fuel through the rail, unnecessarily heating the fuel and robbing the engine of horsepower.

You doing it youself or getting some one else to install it? If yourself, get a Nismo/Tomei one, piece of piss to install and no 1/4 tank bullshit surging. Trust me, when you have to install the 040 you will be kicking yourself for not spending the extra coin on the nismo/tomei one. They are annoying to install, helped to do one in my mates 15, never again.

slice of urine in a R32 GTR...15mins tops. If put in right (in the bucket with the proper mount and clip) it wont surge as the bucket is filled by the reg. return line.

Yeah but is that because you have done 14,000 of them? I'm sure if i did one again now, it would take me half the time. However if this is his first attempt (like mine was), im pretty sure there will be some swearing involved.

However maybe you are right and R32 GTR's are easy, never done one of them personally.

walbro assume 15v for their flow levels so in a skyline @ 12v the flow is much less

recommended as the others have said are bosch or nismo items (perfect fit guaranteed)

Had same probs with gtr making 340kw running a little close to the edge fuel, Installed a Bosch 023 intank (using the DIY thread on SAU) and added an adjustable regulator bumping the pressure up a bit from 30 to 45 PSI and it has solved the problems.

Pump-$170 new

Reg-$165 new

Clamp-$5 new
