All I did was change my darn Racor
filter!!! I put it all back together and started bleeding the lines with the hand crank of the lift
pump. I've bled'em over and over and over again. It'll look fine... I'll start the engine
... it'll run for about ten minutes... and then, kaput! After that, I'll open up the bleeder on top of the engine
mounted filter and find it full of air.
Obviously, I'm sucking in air. But where???!!! OK, I could be pulling the air in anywhere from the lift
pump back to the diesel
tank, right? But the most likely places where the problem would be are where I messed with stuff.
So, I pulled it apart again. I chopped off the old ends of the hoses that attach to the housing and reclamped them. I took the filter apart and tightened everything back up.
But I'm still ending up with a bunch of air! I feel like I'm on crazy pills!!!
Now, I'm thinking that something is not seating right on the racor
, but How could I make sure? I don't want to just go and buy a new one. The whole thing is like a hundred bucks, and if its fine, I'll be stuck back at square one. After all, what if my darn lift pump itself is letting the air in?
I was thinking about TEMPORARILY applying something to the outside of the racor, around the bolt head
and around the filter (maybe a putty or adhesive) for troubleshooting purposes. I was thinking that maybe I messed up the threading on the filter housing, thus causing the leak.
Any suggestions, ideas, words of encouragement???
