Shops or LS Guru's - Question
 

Question for you guys:

Has anyone ran into a issue like this:

I'll take a ride in my car through my neighborhood and the car stalls/shuts off sometimes after a mild curve or left or right hand turn. Also sometimes after a curve, I'll hit the gas to make it up to a stop sign and the car shuts off?

The car does it at any fuel level in the tank. Car has a L92 FI set up.

I've sent the tank back to Ricks and they made a adjustment, but it's still happening.

Any suggestions?

Are you sure it is a fuel issue? do you have a gauge showing the pressure drop?

no. I'm assuming.

I know I can't fully fill the tank up at one stop. Gas spits back out at me if I try and fill at full pressure from the pump. I have to nurse it.

Does your fuel pressure regulator have a vacuum line? If that hooked up and working?

Did it work fine when first complete and then break or has it done this all along since it was new?

my buddy said no vacuum on the regulator. Car seemed fine when I got it, I drove it for a few days straight and my daily was in the shop.

Do you have a vent hooked up to the tank (like a II Much or Finch style setup)?

Could be a venting issue. Try a drive around the block without the gas cap on it.

Yes, I am running a II Much vent

Did that at the recommendation of Rick's Tanks, issue still happened. I am also using a stock '55 gas cap. Rick's said that was fine.

I would try and see what the fuel pressure is doing when it happens. Maybe you have a pump going out.
