in-tank pumps

[Cowboy_80]

I keep reading all of this stuff about in-tank pumps going out, and being a giant PIA to replace. What's the problem with just gutting the bad pump and using it just as a pick-up for an in-line electric pump? It would seem to me that it would solve a lot of problems, save some $ and make replacement easier.

Electric inline fuel pumps are terrible at drawing (pulling) fluid. They are great at pushing fluid.

If you use an electric inline pump, you will need to mount it below the bottom level of the tank. Even then it may starve on some inclines if the tank is not full.

Since most stock pumps last 100,000 miles+, IMO it's a moot point. Guys that wheel mention problems where they fail someplace where you can't access them, and that's a valid concern.

Other people that probably hate it are the rust belters, since removing the tank is probably a pain. Then again, probably preventing future problems due to the corrosion.

Replace with AC Delco, leave it alone for another 10-20 years.

What about a self primer?

Good point.

Also in tank pumps are just more reliable and last longer. They really are not that bad to replace as long as you get most all the gas out of the tank before dropping it. Some people here cut a hole in the floor just above the fuel pump/ sending unit. So they can replace it without dropping the tank.
