I was "going through" my recently purchased ty with a full tune up. I went to replace the fuel filter and I got the fitting in the front lose but previous owners that had replaced the fuel filter, used regular wrenches instead of line wrenches and rounded it bad. PB rust "stuff " has been applieed and I have tried to loosen it without any luck. What is the easiest way to replace this fitting? I'm not looking to replace all of the fuel lines with braided ones.

Re: help with fuel line fitting
You may be slightly hosed.....let the PB Blaster (good stuff!) soak in for a while, and try again. Unfortunately if it is bummed up badly, your only choice may be to use vice grips and get the thing off. If its rusted badly and won't easily come apart, you'll probably find that if the threads break loose, the threaded part will be rusted to the actual fuel line, and it'll start to twist the line as you loosen it.
If I were in your shoes, I'd loosen it however you can, and replace the line between the tank and the filter. Unfortunately, the tough part is going to be attaching to the sending unit, because the male fitting there is the same as the fitting going into the fuel filter. You need to find a female hose end that will fit this fitting.

Once you find that, get the hose end, 6' of -8AN braided hose, a -8AN straight hose end, and the above fitting, and you'll be able to replace that whole section. I've never felt comfortable using rubber line and clamps on fuel injected systems, or compresson fittings to bite onto existing metal lines. When I used to work at NAPA, they sold the above fitting and a 6" or 8" section of flared 3/8" line, specifically for fixing situations like you have. It hung on one of the spinning trees in the showroom. It would screw into the GM filter, and gave you steel line to bite onto however you decided to do it. I don't know if they still carry such a thing or not; that was 8 years ago.

Re: help with fuel line fitting
you could also get the 16 mm fittings that fit our factory fuel lines... you will need one female 16mm -6an o ring fitting and one male 16mm - 6an o ring fitting.. a few feet of braided hose and wala... it's fixed. i can make the hose for you for about 75.00. 2- 16mm fittings,one 45 degree -6 fitting, one -6 straight fitting and a couple of feet of -6 hose and you are done...i would take about a week to make ...i am real busy at work..plus i would have to order the o ring fittings i used mine up making all new braided lines for my feed and return lines.
