Eating Fuel Pumps.
My 81 is eating fuel pumps . I've put 2 working junkyard fuel pumps on it that worked for about a week each and put one off a running truck on it and after about 3 days it started sending all the fuel out the return line an none to the carb . i plugged it off an run it for a day or two then that one was done for an now i sit debating whether or not to buy a new factory style fuel pump or put an inline electric fuel pump. Opinions ? only thing i can think of thats wearing out the fuel pumps is the fuel line is bigger than factory an it maybe takes more pressure to pull it to the engine or something. any similar issues?

What's the condition of your gas and gas tank? I have a buddy who had an old Ram that had a rusty tank, which isn't good of course, and then he siphoned some gas from an old tractor and put it in the truck. That gas was like varnish, and his pump stopped working a few days later. Of course, that could be coincidence....

I went to an in line elec fuel pump (low press). Has worked great. Had to do it because manifold for dcoe's wouldn't fit with the mechanical pump.
My '81 had a 1/4" ish plastic spacer between head and pump.

Can't remember if mine started with a metal spacer or not...but the dealership sold me a thicker plastic one that's on there now. At least that's what I remember...it's been awhile since I've done much more than routine maintenance on my truck and some of this stuff is starting to fade a little...

Make sure you have the right spacer and two gaskets installed. I this doesn't help, check the eccentric on the front of your camshaft. It could be broken and damaging the fuel pump lever arm.
