Power loss!

[macka]

Hey guys

I get some sort of fuel cut when i dump it around corners it splutters then its off again.

What do you reckon?

When in a straight line its ok but sometimes does it between gears when my petrol tank is under half full!

Got a new fuel pump installed not long ago maybe its come off the bracket and now sideways in my tank?????????

Dont know what else it could be......

cheers

polly because the shape of the fuel tank in skylines, I heared from the compliencer that skyline fuel tanks are kidney shaped one primary and sencondary next to it(or similar) so when fuel is low or cornering hard the fuel moves to one side away from the fuel pump then you get fuel surge... and looses heaps of power!

It happend to be once when I was running very low on fuel with lights on in fact I thought I blew some thing but then when I filled her up all went fine!

so I presume that shape of fuel tank is the cause... or perhaps you said fuel pump is out of bracket!

cheers

definately sounds like a fuel problem.

I had the exact same problem, except it didnt matter about corners or how much petrol was in the tank.

Barrie discovered the pump was breaking down, and fixed it, yours is most probably like you say, the pump has come off, or you have some crap in the tank blocking the pickup or something.

hmmm, delving into the petrol tank, not a nice job.

What pump is it? new or secondhand?

my car does this also around corners..

Is it hard to flush out a fuel tank.. hmm .. maybe i should leave

it to the experts.. don't want to be playing with fuel on a hot day..

Its a brand new Bosch 910 fuel pump.

As far as i know there are no drain plugs well none that i could see when i was going to drain the tank.....But if it was crap in the system it shouldnt happen only around corners i wouldnt think..

Have you seen how many wires are actually in the fuel tank?

that scare the shit out of me 1st time I saw them in there....:eek:

I think it's time to fit a surge tank. Use the old pump to take fuel to the surge tank and the bigger unit to the injectors. This will also make it easier for future upgrades cos you know the fuel set up is ok.

It ain't as expensive as it sounds but takes some thinking out.

Whats ya feul pressure running at?

[macka]

I want my boot! so no surge tank!

Um havent measured fuel pressure altho if it was a pressure problem it would arise when on hard boost not around corners

[Pva_Glue]

How do you test fuel pressure?

or

maybe get another guage...

cheers
