Well. attempted on changing my fuel filter.. And unfortuently the line split in half it seems. I cant see for sure because its on the top part closest to the body but it feels like it split. Its the fuel line that goes from the filter to the tank... Am i going to need to drop the tank to fix that line or is there a way to do it without dropping the tank?

 

naterman35,

There are two methods of fixing it. The quick way and the right way. The fuel line will be experiencing higher than carb fuel pressure. So that being said, you should follow the line back and replace it at its next coupling point. I believe its at the tank. It is possible to cut the line a few inches back from the initial split use a brass fitting and a hose clamp tighten it down then get a length of hose to fit over the other end of the brass insert which would attach to your fuel filter. Hope this makes sense.

yeah i was thinking dropping the tank would be the correct way of doing it. Haynes repair manual suggests using a rubber hose which for now might have to do. I cant seem to keep this car on the road for over a week.. Grr.

 

I did the same thing two months ago, the lines are so old that when I tried to loosen the filter the line cracked. Your best bet is get a gm replacement, its about $40 and it goes up to another hose that leads into the fuel tank, you do not need to drop the tank, follow the line you'll see what I am talking about

 

I did that before, I put a bubble flare on the tank line, rubber hose, bubble flare- new line, compression fitting - reused saginaw fitting- new o ring

bang all set

 

Advance Auto Parts, and others I'm sure, sell a repair kit for around $12. It's an 18" length of 3/8" pipe. It has the connector for the filter on one end and a compression fitting to attach the other end to a clean spot on the existing line. Worked great for me. I think Dorman made it.

 

Ah shes fixed. For now all i did was got like 3 foot of fuel line rubber tubing... shortest length they had but oh well. And cut the split part of..put a section like 4 inches long of silicon and slid the rubber over the old tube for 6 inches because i cut my piece way longer then needed. Put 3 clamps on that... Then took my brass fitting and put silicon on it and slid it into the rubber tube. Then hooked it all up. unfortunately the first time i went to start it had a massive leak. Fixed that... Then started it back up and i have a very very small leak but i decided to grab some grub regroup and go and fix that in a half hour or so... But she ran WAY better with the new fuel filter.

 

That's really not safe, especially if you used regular fuel hose. The pressure there is 50-80 psi. It needs to be all metal. If you must use rubber, it needs to be high pressure hose.

 

Im not understanding how it isn't safe?. Its fuel line hose. Its made for this.. If you've read Haynes repair manual for the third gen Camaro you'll notice that is how it is said to be fixed. I feel safer having a rubber hose thats made for fuel lines then the rusted metals ones that a great deal of people have on there car. In Haynes it says no more than 6 inches of a gap should be used. Mine is 4'' of hose and then another like 6 inches that i slid over the old tubing. Silicon used to ensure a good seal... If im not correct i did it just as the repair manual stated. which im sure if it wasn't safe why would that be the way to repair it then?

 

Because regular fuel hose is made for low pressure use. The stuff for high pressure is sold by the foot (about $6/ft). The low pressure hose may burst. Hose clamps are not safe for that pressure either, especially where there is no barb on the end of the line. They can get lose over time and hose can slip off. The hose can also tear in an accident. Regardless of what Haynes says, only metal or specifically made flex hose is safe at that pressure. We're talking about high pressure gasoline under your car. Take no chances.

 

What about repairing the lines where you had to cut them, would a simple compression coupling work?

Replaced my fuel pump and now i need permanent and secure way to connect fuel lines together again. I do agree that rubber hose just looks weak. Plus if you're already having a leak, imagine what would happen if you were going around town and that happened on your flaming hot muffler and tailpipes.

 

Yes, use brass compression fittings. That's what the line repair kits come with.

 

 

Regular fuel line hose is meant for low pressure, you'd need fuel injection hose. Fastest way to tell which it is, is to look at the hose... if you can't discern a pattern from the braided sleeve it's probably not FI line. Since you've been working with it, you can also tell when you cut it: FI line is tough and has reinforcement throughout, regular low pressure stuff is soft rubber you could cut easily with a dull knife
