im almost done swaping a 5.3L in my 82 c10, but im stuck on the fuel system. i bought a 87 sending unit so it can accept an in tank fuel pump. but im not sure which pump i need. i was looking at the walbro pumps and the ac delco. any help is appricated.

 

Need more details.

Are you using the 82 Fuel tank, or an aftermarket?
The Sending units - to my knowledge should all be 90 ohm, but I could be wrong.

FG0053 is the pump that went on my 99 5.3L, but it has 3 outputs. One is for Feed, One for return, and one for the vapor canister.
This pump will feed the 5.3's and the 2003 SS 6.0L trucks.
I bought mine on Amazon for around $230 just a week ago. It comes with the tank seal and adapter harness.

You'll need to get the Dorman quick connectors for it.
Otherwise, you can go aftermarket and put an external pump on the side of the frame rail. It's gotta support 60psi.

 

i would just go with an external walbro 255lph. $109, and you have plenty of room to grow with future mods.

 

thanks i got a walbro 255lph in tank already.

 

hey the switching valve needs to be 65 psi and the fuel pumps if its duel need to be 60 psi u can order the pumps @ street and performance ask for mark he helped with my 87 chevy shortbed swapp the number is 4793945711

 

thanks i only have one tank, i dont need the switching valve. thanks for your help. i called S&P and got what i needed.
