So, I am really getting tired of the amount of air my CRD is sucking into the fuel lines. I'm planning on changing out the quick connects at the tank; I do have a frame mounted lift pump. But as I was planning the work I got to thinking: Does anybody ever glue (solvent weld) fuel line onto plastic tank fittings? There are fuel hoses available with PVC liners, and it looks like the fuel tank fittings are PVC as well. Anyone tried? Any success?

Assuming it's possible why bother and could make life more difficult later? All you need is a bit of marine grade diesel rated fuel line and like 4 stainless worm clamps. You only need to do the supply line as the return line is not an issue.

Just wondering here, would it be advisable to cut the quick-disconnect flange off the hard line to the filter? This would allow the new line to slide farther onto the hard line.

yes ,i did it all new rubber fuel lines 2nd gen ff housing ,didn't stop air in fuel , at that point i install in tank lift pump $$$ problem solved

Well, the new hoses seem to have worked wonders for me, I can really feel the difference with no air in the fuel. I did not modify the connectors, but I did use the fancier fuel injection type hose clamps.

As to the idea of gluing the fuel line, it does seem that the factory actually does that on some of the fuel return block fittings. Not sayin' it's a good idea, but at least there's precedent.
