Hi
I put the vac pump on the return hose so that it was pulling through the whole system and pumped till there were no bubbles - passed about a gallon through. Hooked up a charger to the batts and it cranked fine. I let it run for a few minutes just to see if anything would go wrong. It ran a little rough - still sucking air. While at idle I hit the schrader and lots of air and foam came out. So the pump seems good and now I need to look for leaks. The Greasecar guys suggested I check the o-ring between the FPR and filter and plug the orifice in the plastic cup thing on the FPR.

Any suggestions on finding an air leak?

Thanks again for your time
