I'm going to be pulling out my fuel tank on my 03 gmc sierra 5.3 4x4 to put
in a new fuel level sending unit, I was concidering putting in a walbro fuel
pump so that I would have sufficiant supply for future upgrades while I was in there, but I am unsure on the exact model and install. I've searched quite a bit and I am confused on wether a walbro pump can be installed on a return fuel system, wich I think I have?? any treads on the install would be great also.
thanks

 

any help please? I am new here. I was planning on ordering it today.

 

yes u can put one in with a system with the return line. TSP is a good place to call and they will hook u up with everything u need or have questions about the install.

 

thanks, I just ordered it. u know if there is directions for fitting??

 

Lonies performance to the left has a double pump version.

Holty is runiing one ,Hear they are Bad A$$.
