inline fuel pump vs intank fuel pump

I have a 1998 ZR2 Blazer and need to know if I can use an inline fuel pump instead of a intank. I have the intank right now and its bad.


If so, can I leave the old pump in the tank and just install an inline pump?

Nope, the inline would have to pull through the running clearances of the intank pump.
The fuel gauge sending units were not the best design so you'll get a more reliable fuel level sending unit too when you replace the whole module with a new AC Delco.
