Default bypassing in tank fuel pump?

92 chevy 4x4 1500, has a possible in-tank fuel pump problem. My question is: Can I add a in-line electric pump, without doing anything to the in -tank one? Will it draw gas thru the bad pump?

Probably not efficient enough to run and would probably burn up external pump from heat of trying to pull through tank pump.

No you can't suck gas through a dead pump. Plus a replacement pump is cheaper them a aftermarket pump and regulator. What's the problem with the one in the tank

Thanks for the replies, kinda what I thought. I've replaced intank pumps, and its a pain in the butt. This is a older truck, I think I'll cut a opening in the bed floor. I've ran hot wires right to the pump, and cant get it to turn on. Its not the OEM pump, it was replaced some time ago.

Thanks again

Just unbolt the bed and move it back.
That is better than hacking a hole in the floor.

I changed the pump in my 94 k1500 that was the original I believe, this past fall. I put an extension and socket on a impact gun, soaked the 2 bolts holding the tank up in pb blaster and they came right out. Went right back up just as easy. Try dropping the tank first, usually people freak out and make it harder on themselves. I swapped mine out (tank was pretty empty so it helped) by myself with the help of a floor jack in less than a few hours.
