People on here have posted about a variety of aftermarket pumps, like Airtex.

 

Thanks! Paul is sending one tomorrow!

 

Installed used pump from Paul Grant...would not pump. Checked inertia switch. No change. Bypassed inertia switch and PRESTO!!!! TRUCK STARTED!!!! And RAN!

So regarding the inertia switch, can they be fixed or do I just replace?
(And yes I did try bypassing inertia switch while old fuel pump was installed.)
