IP Problems

[steve777]

I think I am having issues with my IP. Symptoms are that a week ago I was driving over to a friend's, when suddenly the truck had no power going up hills; it would stall frequently, especially when under load. At the time I thought it was a fuel issue, because I still had a bunch of biodiesel in the tank and it was cold that day.

Today, it was much warmer (and I added 20% D1 to the tank), but I started seeing similar symptoms when driving (turned around and took the car instead). It's not likely a fuel issue now with the thinned down fuel, so I am looking for an air leak or IP problem.

From memory, I recall the trick of replacing the return line with clear plastic to see if there are air bubbles in there. I also sortof recall taking to top cap off the IP to see if there is plastic floating around in there, but I thought there was some special way to reassemble the pump after doing this to avaiod a run-away problem.

Anyone recall the details of openning up the IP and putting it back together?

Any other suggested areas to look at for this problem?

TIA

Check your email in a while........... When was the filter last replaced. You can divert the IP return fuel into a clean margerine container your looking for black specs. Does the blocked filter light come on or even work.
