filter

[miked.]

ok, changed filter on the fpr, blew out the lines, and put on a brand new tank. ran good for 20 miles, sat over night. this morning nothing. would have set fire to it if it had not been sitting next to the barn with my horse trailer hooked to it. got no pressure behind the air bleed valve again. so i took the fuel filter out and tried to crank it. got pressure behind the bleed valve instantly. then i cranked. my question is how much junk in the filter will keep it from starting? it was not visibly dirty
