Come on truck....please start....
Experiencing fuel problem:
The truck starts fine every morning. Once I drive 15-20 miles (get the motor warm), and turn the engine off, the truck will immediately restart. However, if I wait 20 minutes or so to start the truck, it becomes a chore! It will take 5-10 attempts to fire the engine (if I can get it started), straining the battery. I even tried starting fluid, so I’m not sure it’s starving for fuel; it seems like vapor lock??
I don’t know if this is a coincidence, but this started happening at the same time I installed a new tank. I checked all lines, fuel filters, etc. I even drove with the tank cap off to make sure it is ventilated. Plus, once started, the truck runs fine. My previous experiences with fuel-line vapor lock usually resulted with sputtering or stalling while driving. Any ideas? I’m planning to add a Performer and 650 4brl, guessing the problem is carb related, but I’d like to diagnosis the problem before I start spending $$. Motor is a 71 FE360 in F250 4X.
Thanks

One thing that needs to be established is if it actually is getting fuel. When it is hot, and starts doing this, pop the aircleaner off, and see if it squirts gas down the carb. That will help to isolate the problem.
If there is no gas, it may be boiling the fuel out of the bowl on hot-soak, so you have to wait for the pump to get fuel into the bowl before the truck will start.
