Hello, We have a new/old Chump Car that we've got almost ready. In testing last week at Homestead Motor Speedway, we found the engine would stall because of fuel pressure or lack thereof, in left hand turns. My track fix was to pour more fuel in it. It would run normally with 16 gallons in it, but after 5-10 laps the problem would reoccur. The track runs counter clockwise so this is quite a problem. Essentially, we are able to use about 3 gallons of fuel if we're filled up. We have an SU Carb set up with a 1978 fuel tank, running the return system for the fuel to return to the tank. We were able to get fuel pressure and run the new engine in the garage with only 3 gallons in the tank, so I feel we at least have the pick up plumbed properly. I have run many street cars on the race track and never had this problem. Any ideas for me to check? Thanks, greg ira
I just put my car back together after my budget restoration. I had removed the fuel tank and painted it. When I reinstalled it, I had some difficulty finding anything to reference where the fuel tank nipples connect to, but I connected the bottom nipple to the outgoing fuel filter. The fuel pump is kicking on, and there is a little gas in the bottom of the filter, but it doesn't seem to be building pressure. I replaced the rubber lines under the car and have them tightly hose-clamped into place. If it matters, my car does not have a charcoal canister under the hood. The metal fuel line that connects to the canister is sitting open. The tank has ~7 gallons in it. Maybe the fuel tank doesn't have enough fuel for the pump to prime? Thoughts?
