What is inside the fuel return line orfice to the filter top mnext to the schrader valve. Did a clear line check for air and had lots of air back to the filter. Couldn't blow or suck thru the orfice, so ran a needle thru it and retried air check, now the air goes back into the filter and clears to solid fuel. There seems to be some kind of check (rubber ?)inside the fitting. Motor seems to run alot quieter now. /ubbthreads/images/graemlins/shrug.gif

There should be a check ball and spring....... you can remove the whole thing from the filter header....... carefully take it apart and check the ball and spring.

That would be reverse of what is intended....bleeding off any filter header air to the return lines is it's intended purpose.....so double check that, do you have the loop in the clear line to indicate which way fuel/air is going.
