how would i "know" my fuel pump is bad?
So today I got a new pump and began to tear my valley apart. Unfortunately. I was two tools short... an extension for bowl & I'm guessing a 1-1/8" wrench to get bolt attached to banjo loose..
Reason I'm changing is I'm getting no fuel to the bowl and pump has never been replaced. With filter out and diesel poured in bowl the hole on the top towards firewall bubbles alot ..
Once I get pump out is there a way I can test the old pump. Be fore essentially blow a Benjamin putting the new one in?
