auxiliary fuel tank

[dinkydau]

I am considering adding a fuel tank to my F350, 7.3, 1999 model.
First question: Does this truck have a fuel pump in the fuel tank?
Second quest: If I add a fuel tank & install an electric valve allowing me to pull/pump from and return to each tank separately, should I add that valve before the frame mounted fuel pump, or just how should this be done.

Any/all hlep appreciated.

I would say you have to add a valve before the pump.
I don't know if it has a pump in the tank though.

No, there is no pump in your tank, just a sending unit for fuel level.

as far as how to mount it, i like gravity feeding it into the primary tank if all your gonna carry is diesel, but you want to have it on a dump vavle so you are always dumping. This allows you to keep a better idea of how much fuel you really have.......problem is this requires a hole in the bed. Then just T into the main filler and put the vavle somewhere on the secondary tanks line......

Boerne was a great place to live until uncontrolled growth took over. Now you can not swing a dead cat without hitting someone.

I had twin tanks on an older ford and ran of a pair of switches (wasn't factory and there when we got the truck). First switched between tanks, Second switched b/w sending units so you could see both tank levels.
