Fuel pump or what?

[TruckinDaddy]

I have learned a lot in the past year about my truck, but when it comes to engine internals, I am a total nube.

I replaced the original fuel pump on my truck a couple of months ago with an AutoZone $15 lifetime warranty pump. Now I am wondering if it might be bad. I checked the oil this morning and it was way past full on the dipistick. It was really thin and gas smelling, so I think I need another pump.

Also, I recently cleaned out a bunk of gunk and rust from the fuel tank, so maybe I am just tearing them up because of that.

Any ideas on what else could it be? Is there a bigger obvious problem that I am overlooking?

The truck was running fine last week. The oil did not have but a hundred miles or so on it.

Thanks for any ideas or suggestions.

I think you found the problem, they can fail and leak inside, but usually they leak outside. Of course, change that oil and filter. When you get the pump off maybe you can see if there is gas on the inside.

You can add a fuel filter under the cab in that rubber hose for a while until the tank gets cleaner, might restrict the fuel some, but many would not recommend having that in there long term, your call, maybe worth a try.

Had same problem . We installed an electric F/P and a filter before the in and a filter at the carb. runs much better .Good luck .

Thanks guys.

Swapped the fuel pump and added a filter under the cab. Truck was running good until I ran it our of gas... GRRRRRR.

Good thing I was right in front of the house still. Guess I need to fix the fuel gauge now.
