The Stovebolt Site Forums The Shop Area General Truck Talk All rubber fuel components failing at once

I am about to replace my third fuel pump on my 55 235 in ten years. Something is going on. All have failed causing the engine to sputter and shut down. After I shut the engine down and wait for a few minutes it starts and runs fine until the next 25 or 30 minutes. All have been purchased from Napa. They just stand by the warranty and give me another pump.
