HELP!!! Rusty (Leaking) Fuel Lines on 4.3

Hey everyone!!!

I just bought a 1993 4.3 w/ Z VIN automatic. The body is in great shape but is kinda rusty underneath. My mechanic changed the fuel filter and the truck is now very slowly dripping gas. It is coming from the section of line in front of the filter. The lines are really rusty. I priced the lines from GM dealership and they are $150 for just the back section. Does anyone know where I can get these lines at a good price online??? I will pay a fair price if anyone has a parts truck laying around with good lines!
Even thought of letting all the gas out and trying to patch with JB weld. Not sure how it would interact with gas. TIGHT BUDGET!!! Thanks for any ideas!!!

have you tried junkyard? have you located the leak? for a temp fix you could cut line on both sides of hole and replace with hose and clamps. (just temp fix). make your own or take old line off and measure it go to autozone buy straight peace and take new and old peace to a shop to bend the new one to shape. probably half the cost of a new on there.

The mechanic said I couldn't create my own lines because of some pressurized fittings or something? Not sure.

On a "W" type motor I could see a problem as they have high fuel presssure (54-61lbs plus) but a "Z" 93 should only have 9-13 lbs of fuel pressure. I do not see why you could not use a good high pressure hose and clamps as suggested. At least until you get the money for steel lines. You do not want leaking gas which is what you have now. Might be a problem where the leak is close to filter. Unsure what to do if this is the case but I would think an in line fuel filter would work. Also, MIGHT be possible to buy compression fittings and splice this thing. Any other thoughts on this?

compression fittings. but my dad says if i get the fittings there should be no problem making my own lines. I'm still thinking of tryihg the JB Weld. I just thought I'd run the truck until the gas runs out and letting it dry and then patching it.

JB weld is at the very best a tempurary fix, and i wouldn't even trust it at that. I might trust it to get me to the next town for parts.

Brakes have way more pressure than you'll ever get in your fuel lines, and they never have problems when they replace the brake lines with the proper ones and labor done right.

So I can't see why you can't fix the fuel line yourself.

Autozone or Napa should be able to get you all the parts that you need.

If the leaking fuel line is under the box I would lift the box and survay the damage. It might just be a short section that needs replacing, and an easy job

i have a 98 blazer 4.3 'w' vin on my way to work one day i noticed a strong fuel smell. i got out and looked and saw i had a pin hole leak on a rusted fuel line by the fuel tank spaying right on my muffler. i prayed and drove as fast as i can to a parts store. due to lack of time, replacing the line was out of the question. i bought a section of rubber hose same inside dia as the outside of the fuel line, and some clamps. cut the hose lenghtwise so it formed a 'c'. wrapped it around the line and clamped in three places. it was i temp fix so i can get to work, but a year latter it's still holding.

I really don't think that we should list repairs like that on the main forum, because it's just a temp repair that isn't safe in the long run.

And some people will try it, and think that it'll last for longer than the life of the truck.

I'm not condeming the idea, and i know that it works as a tempuary fix, but I personally wold like to see temp fixes like that made through PM's

Try pricing it at GM parts Direct, or you can try the s10warehouse on eBay. He buy S-10s and strips em down to sell.

Lets use our brains here a little bit. :disappoin

You are talking about a potential safety issue here...fix it right the first time..spend the money for the correct lines and fittings.
Fuel lines and brake lines should be correctly done.
