I just converted to E-fuel and i'm going to run some 5/16ths clear vinyl tubing on the suction side for a month so I can see the fuel going in to the pump. I ran it last nite and could see no air at all in the line. That makes me feel better..



Thought i'd share my findings with ya'll

 

I always wondered about that, thanks. Reps sent.

 

Keep an eye on that vinyl tubing. The diesel fuel could eat through it.

 

Yeah, I did this to a VW TDI once and found lots of bubbles. When I got the problem solved I put the regular hoses back on.
