Fuel pump doesn't stop priming, low pressure.
I just bought a 1989 Daytona Shelby from a guy in the Baltimore area, 2.2 cb, 555 Mechanically restored proper bumber to bumper (rebuilt engine, tranny, new suspension, steering), but stage 5 with meth injection, all sorts of other go fast goodies, with a billet fuel rail, and fpr with a convenient pressure gauge on it. Extremely convenient, because 200 miles into my 540 mile return trip in the car, it died in Grantsville, MD.
Once you turn the key on, it primes and keeps on priming, stopping only if you turn the key off. It only primes to about 40 or so pounds, then drops to 20ish while cranking. Pressure holds when the key's off so definitely not leaking.
Before dying, the car drove mostly fine and started right up, but would fall flat on it's face if you do any more than about 1/3-1/2 throttle.
Given the symptoms I'm almost completely sure it's the pump or filter. I had nowhere to stay, and didn't have the luxury of ordering parts and waiting 2 weeks, so we towed the car to a local shop and returned back to Cincinnati, took the walbro off my totaled spirit and got a new fuel filter. I also grabbed a spare Fuel rail and FPR. I'm fairly certain the car should survive the drive after this is fixed, but grabbed a spare SBEC, Map, TPS, turbovan injectors, and some relays anyway.
I'm about to make the 340 mile return trip to Grantsville to rescue the car, and hopefully drive it home. Is there anything else I should try to obtain, or would that about cover it?
