Well I posted my issue with the PCV valve that had a loud chatter ... Turned out to be a leaking fuel vac line at the tank. Found out by clampimg off both the vac lines from the canister. Now I need to get to those small tank rubber lines and replace them ... Just thought I would let you know what I found ... May save some time for someone else.... MIke

Cool. Be sure to use fuel rated hoses.

Loosen the bed and tilt it. I've done it. Using a 2X4" or blocks to hold up the bed.

Tnx I will try that ... I got some heavy tool boxes that will have to come out to do it but I figure I'll replace both sending units while in there? Is that the best way to get at the dual tank fuel valve too ?

If I lift the bed off my truck again, I'm replacing both sending units. Worth the time. I've used an engine hoist to lift by myself. I do have to take the bed off one more time. The read will get rust proofing and cleaning. A behind the roll pan hitch will also be strengthened for use.
