Hi guys
Iam building a cortina and using a Commodore tank which I beleive might be from either VN-VP or VS-VR 5L. The tank is the large 80L tank and has a single fuel pump in it. It has the return line on the tank though as seperate to the fuel sender and pump unit.
I want to replace the fuel pump with a Walbro to supply enough fuel for me but don't know which one I need. I think it might be the GSS342 but Iam not 100% sure.

Any help would be greatly appreciated. I can supply photos of the tank and sender unit if this helps.

Thanks
