With two pumps dropped in my tank, my engine starves on strong right handers and on aggressive driving when the tanks anywhere below 3/4th's. I've recently fitted a fuel pressure sensor and confirmed it, fuel pressure drops to as low as 3 psi at times. CJM has no solution for that yet so I'm looking into an external surge tank setup, something like this squeezed in my spare tire area.



Anyone attempted anything like this?

 

No one even attempted this?

 

No one has attempted an RB swap either except you. You have to blaze the trail for everybody else.

 

Should be plenty of people who can help you on the skylinesaustralia forum Sam. Doubt that you'll find many V36's with this issue.

 

I am signed up on skyline australia, but all those with V36's are stock and more than happy lol

Looks like I'm alone on this as BB said!

 

Not even sure what this does so... Sorry Sam .

 

Sam,

Look into this - GTM Motorsports FUEL SYSTEM GTM FUEL PUMP VOLTAGE STABILIZER KIT

then this - http://www.summitracing.com/parts/rci-7050a/overview/

Thank You and come again.

 

I'm not sure it's voltage issue to be honest.

 

Is the feedback from the fuel pressure gauge blipping from high to low or is it slowly changing (lowering) as a result to driving more aggressive?

If it changes rapidly: Fuel sloshing

Slowly: Voltage

 

Yup it's rapid. I'd be coming out of a right hander with fuel pressure at a constant 47ish psi and as I start putting my foot down I get an immediate cut with immediate pressure drops, I make an aggressive left lane change and all the fuel goes back to where it should be haha
