Check those fuel lines. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So a few weeks ago I was driving my truck with the new 350 in and getting the "kinks" worked out and everything dialed in. On a run down the toll road she sputtered and acted like she was going to die. I dropped down from 70 to 60 and she caught back up and I made it home.
Sense then I have been running around and have not had trouble. I thought the problem could have been electrical so I invested in a better distributor and replaced/added ground straps. Everything thing ran perfect the 30 miles to my friends house.
On the way home she died on me 3 times. The third time I thought to myself, this is not electrical because I can pump the gas and it will fire and then die. it has no fuel.
I thought maybe a clogged fuel filter or a bad (new) fuel pump. I looked down and the darn rubber line has a 90* kink in it. A couple of zip ties form the tool box and I get her home without a hitch. I think I will grab a piece of hard line to make the bend so the rubber does not have the chance to kink. BTW the rubber line is about a year old so maybe its just that time.

Always good advice. Personally, I use as little rubber line as possible. Only a short length between frame and pump to allow for vibration and movement. And never near any hot exhaust.

I'm in the process of replacing all mine too. By chance I was replacing my fuel pump and filter, when noticed how cracked the old ones were. Then I realized that they're about 12 years old. Way past ready.

BTW the only rubber line I have is the short piece from the hard line on the frame to the pump and the short piece from the tank to the hard line. the kink was right in the bend to go from the hard line to the pump.

I bent up a custom hard line from the pump to the carb.
