Electric Fuel pump question

[Joshinator]

Ive got a 96 Vortec 350 in my K5. When you turn the ignition on, the fuel pump runs like normal, for about 6 seconds. Now, its also running for the same 6 seconds when you turn the ignition off. Anyone have any ideas why its running with the ignitioin off?

AFAIK it is common for the pump to run a few seconds before and after the engine has started.

my stock 96 c3500 with same motor does this also.

It's to keep pressure in the line I believe.

Y'all are right!!

Yeap, it is supposed to do it. Had to do some research to find out. I guess since ive moved the tank i can just hear it better than before. Thanks for the reply's fella's, much appreciated.
