Hey guys. I'm new from knoxville tn. I have a bone stock 1990 cummins 4x4 with an auto. Had provenance with the pump leaking from 4 spots Got a rebuilt one with a 3200 gov spring and turned up with aftermarket fuel pin. This was a farm truck. Bed is bent and don't have a straight spot in it. But after I have the pump put on because I don't know hoe I will be puffin in a 6 inch stack. Soon will have gauges. Any advise for these trucks will be helpful. Only has 228xxx!
