Hey guys I think I know the answer to this already but just wanted to throw it out to see if any of you have come across this. Went to change my fuel filter the other day and noticed the flare nut on the fuel line on the filter side closer to the front of the car is totally rounded off. I think there are two corners that aren't totally round and the rest are trashed. I got the side closer to the rear of the car off bit can't get the other side to move since I can't grab it. I'm also afraid if I do get it off that I won't be able to tighten it onto the new filter. Am I going to have to replace the fuel line to get a fresh flare nut? If so, I've seen Kirban sells a kit with all 3 under car lines but is there anywhere that sells that line on its own? Thanks for any help guys!
 
GBodyParts.com Online also sell it in SS line.

Is this what your looking for?

You also might get away with making your own fuel line from Braided fuel hose with correct connetions. local autoparts might carry some or order connections from summit/jegs.
 
Pep Boys has filters with a flare nut style inlet and 3/8" outlet pipe.

You could just cut the line and install it with 4-6" of fuel injection hose double clamped on that style filter and the existing line once cut loose from the rusty existing filter.

Worked for me for many years. :smile:
 
Are you using a flare wrench to remove the nut?

I tried flare nut wrenched and they wouldn't get any bite, that is how bad this thing is! Plus with the location it is tough to get a vice grip or something on there. The nut that is welded onto the filter is fine, just the flare nut on the fuel line itself is wrecked. Thanks for the quick replies!

That may not be a bad idea for now as I really don't feel like replacing the fuel lines.
 
SalvageV6, do you have any pics of how you've got your filter set up? Also, what did you use to cut the fuel line without putting a kink or anything in it? Does it have to be a super clean cut so no metal is sticking into the ID of the fuel line? When you said double clamped, are you meaning two hose clamps on there or something else? Sorry for all the dumb questions, just want to make sure I'm on the same page, this looks like it is probably going to be the way I end up going for now, quick, simple and replaceable! Thanks for any help on this!
 
I don't have any pics. sorry.

Mine is on the inlet side and I finally used a length of braided teflon hose up to the gas tank area.

I use the Purolator F33173 filter and I thought the other one with reversed fittings was the F33169 but they didn't have one there, or that style so perhaps it's discontinued. :confused:

I know I bought one once because it didn't work on my car and was floating around here somewhere for years but I couldn't find that either I probably tossed it.

Here is another solution however. :)

Buy a Dorman GM fuel line repair kit, for about the same money as a filter and use it into the stock filter as it's set up 16mm with O ring fitting.

Most any good auto parts store should sell them.

Here's a link to Summitt they have them too.

Dorman 800-153 - Dorman Fuel Line Repair Kits - Application - SummitRacing.com

Remember always use neverseize on the threads for the nut and on the lines external body where the nut has to spin and slide on so it can't seize up ever again.

Cut the 18" long 3/8" steel repair line end to whatever fits under the car 2", 3", 5" and cut the stock line to match up with a short length of fuel injector rated hose at that point in between with hose clamps.

I used a hacksaw to cut the end of mine metal off and then a file to smooth the top surfaces and a round file to do the inside a bit only if needed since you can't control the filings even with a dab of grease in there, but the inside isn't important anyway and doesn't get much of a burr.

After the second rust through of the stock metal line I went with the braided teflon. :cool:

I hope that helps, there may be other GM repair line kits with shorter lines and still the proper 16mm fitting and O ring with just a nipple on the 3/8 line requiring a bit less work.

It's a very common repair and that way you would still be able to use the stock filter.
 
The Dorman 800-233 end will also work and is a lot shorter.

You still need to trim it as it swages down the diameter at the right angle bend.

You will have 2-3" of a line off the fitting to put the hose on. :cool:

And it's cheaper. :p

Awesome! Thanks for the kit numbers I am going to check these out, sounds like the best way to go. I appreciate the help. Once I decide which way to go I will post back up and let you know how it worked out.
