I need to replace the fuel filter. The fittings that screw into the filter seem to be rusted to the fuel line on both sides. My fear is that if I try to untighten the lines they will twist up or break apart from the fittings.

What should I do?

Can I repair the fuel line and how?

 

about the most you can do is give it a try and if it holds it holds... but if it looks that bad then id replace itbefore it goes on you down the road when you realy dont need it to.

 

Can I cut the fuel line on both sides of the filter? If so what is the best way to repair this? Can I bend new fuel line and patch it to the old fuel line with rubber fuel hose and clamps or is the fuel pressure too great for it?

 

When you attempt to loosen the fittings at the filter, use two wrenchs. One on the filter fitting and one on the line fitting, if you don't you will definitely wind up with spaghetti for a fuel line. It is also highly advisable to replace the o-ring seal at each line fitting because they are probably rotted with age and will leak if not changed.

 

for a quick fix i have seen people patch both tranny lines and gas lines with rubber hose and hoze clamps... its not the right way but it does work. also i might add that when i replaced mine it didnt look good at all but like said make sure you use two wrenches and you should be fine i repeat

" USE TWO WRENCHES":lala:

 

Absolutely, 2 wrenches are a must. You might also want to spray some penetrating lubricant (wd40 or the like) on those fittings and let them sit for a few minutes before you try to loosen them.

And take off the gas cap to relieve any pressure in the gas tank before you start wrenching, unless you like to take a bath in gas.

If you have to cut the lines, be vary careful. No sparks! We don't want to be reading your obituary.

 

If you absolutely have to cut the metal lines, and you are running FI (high pressure), use two compression fittings, and new end fittings to screw to the new filter. Or you could get flaring tools, and do it that way.

 

two wrenches are a must. also try pb blaster and after it soaks for a few days try some cold, like from a can of "canned air" held up side down
