scott,

You are so the man. Bigger than sheet, there was a missing gasket/o-ring on the inside of that pre-filter. I had to go dig the old ones out of the trash to figure it out, but there is an o-ring, that I would have never found in a million years, missing. Took the old ones off the old pre-filters, and put them on, started right up, and have been runing smoothly for a while now. Will let them run for about 30 min to make sure, but all the lines are solid with fuel and no air bubbles.

Damn the simplest things always get the best of me sometimes. Would have never guess that the new prefilters did not come with these o-rings. Will go buy some tomorrow, to replace the old ones that I used.

Thanks for all your help and wisdom.
