So, I was out making a short trip and my gas line broke. My dad helped me get it home but we don't know what size the hose is. The hose that broke is the rubber hose that goes into the fuel filter. If anyone could help, I'd appreciate it.

Wow, no responses. I'm shocked, haha.

Well, it'* a Saturday, and the weather might be as good elsewhere as it is here.

There is no 'repair' for that line. Only replace. I suggest a wrecker.

I wasn't looking to repair it. I am going to replace it but I don't know what size the hose is because I can't get underneath the car right now after driving it. Guess I'll just wait till tomorrow when I can get a better look at it. Anybody know if Pep Boys or Auto Zone would carry the hose piece and if they'd be open tomorrow?

No, they won't have that line. Dealer or wrecker only. This isn't some universal fuel line situation. The flex line from the filter to the rail or the filter to the tank has custom GM conncetions on each end.

Oh ok, thanks for clearing that up then. Guess my car isn't going anywhere soon then.

BTW 5/16 for that line.

Thank you so much

For what it it worth - About a year ago I had a plastic fuel line under my 97 Blazer rub the transfer case shaft and that made a hole in it. The factory replacement line was somewhat pricey, had to be ordered and looked like a pain to change.

A buddy of mine who is a pipe fitter gave me a brass compression fitting to try. The ferrules were slightly small and were difficult to get over the fuel line ends. I took some fine sand paper and secured it to the end of a drill bit. I then held the ferrules in water while I ran the makeshift "sanding drum" in each ferrule to slowly and carefully open the ID up. I probably took .002" or .003" out of the ID. Then the ferrules slipped over the tube ends.

I cranked the compression fitting together, secured the fuel line so it would not rub the drive shaft and a year later no leaks...

Having said all that, the right way is certainly to replace the line, but there can be (robust) ways to repair things that don't involve duct tape.

Autozone or Oreillys just may have a fix for that fuel line. willwren is right about it being special, but a company called Dorman makes replacement ends and fittings as well as lengths of line for the hard plastic high pressure fuel lines, including splice kits. I know oreillys carried them when I worked there, and I know autozone does too. You may have trouble finding someone who has enough experience to actually know what they are since they're not a common thing the average 17year old at the counter knows anything about. You may be better off searching their very slow website for what you need, and showing them that.

The dorman part number for a "5/16 nylon to nylon compression union" is an 800-145 for a 1 pack, or a 800-147.5 for a 5 pack. Those are coming out of my master kit here at work.

I believe their website is http://www.dormanproducts.com/

This is all assuming that you guys are talking about the same high-pressure hard plastic/nylon lines that I am. If not, ignore me.

Hope this helps.
