I get good suction when I operate the priming pump as fuel is entering the pre-filter and the handle comes up pretty easy. It can't be a clogged tank screen or fuel line from there. When I push the priming pump handle down fuel goes through the main fuel filter and through the clear fuel lines to the IP. I noticed some fuel that was escaping the priming pump handle but that was normal last time I changed the fuel filters. I also noticed some small bubbles in the clear fuel line that is attached to the top of the main fuel filter but that was it (Return Line?).

I looked at the IP today and I still do not see a bleed screw anywhere on top. I might be looking in the wrong place. Can it be somewher in the sides or near engine?
The Injecter lines are of course on the left and near the back of the IP on top I just have a part that looks like a valve and four bolts holding that down. Is it near the shut off valve? I looked in the haynes manual as well and there is nothing in it about bleeding the IP or in any of the pictures.

Thank You
