I replaced the stock fuel filter that resided on my 1993 6.2L engine with a Racor spin-on filter setup. The filter is underneath the truck about 2' away from the tank. I forgot to add anti-gelling additive until the engine started acting up last week. (yeah, I know :rolleyes: ) My 2 micron fuel filter got gelled so I'm replacing it today with a 10 micron. My question is whether there is another air/fuel bleed on top of the IP anywhere? My Racor filter head does not have a bleed screw on top. I do have RectorSeal 5 on all the port plugs but I don't know if loosening, then retightening the plug will then have me leaking from that plug afterwards. I could loosen or remove the hose from where I connected it onto the metal fuel line next to the filter to help bleed air.... I was also thinking of adding an inline Y-valve after the filter to help in bleeding when replacing fuel filter. I'm unsure what to do... suggestions? Thanks.

Replaced the filter, loosened up the hose clamps on the hose that I connected to the metal fuel line, ran the e-pump for 2 minutes. I could hear the air spitting out, along with some fuel. Tightened them up again, took the pink wire off the IP and cranked the engine a few brief times. Hooked up the pink wire to the IP and away she ran! Like a friggin' champ. Meanwhile, my buddy is fighting an electrical/computer battle with his truck at his house. I love my "simple" 6.2L diesel. :)

That's great Tony! Glat it worked out alright.
That think will be running after an EMP while the rest of us will be sitting on the side of the road!
