Yanmar - 6LY - Fuel Filter - Leaking

Postby ChesapeakeLover » Sun Apr 22, 2018 8:06 pm

Good Evening -
I am doing some spring maintenance on my '06 3880. I replaced both fuel filters. After draining the cylinder, removing the cylinder, replacing cartridge, re-installing the cylinder, then opening the 'out' side of fuel line, priming the fuel line by hand pump until fuel comes out of line, tightening the out side and pumping the prime pump a few more times - I am then getting a fuel leak.
Both sides - the center stud that goes through the center of the cartridge is leaking - on both engines. What did I do wrong? I've done this before with no issue - but clearly did something wrong this time.
Thanks for the help!
