Fuel Lines
Ok guys I need some advice. I recently replaced my gas tank on my 95' blazer, it was completely rusted and leaking. Now a few months later, one of my fuel lines are leaking, I believe it is the return, below the rear door. Now I'm wishing I would have replaced the lines while I had the tank down. Anyways, now I am planning on replacing both the lines, but I was wondering what I should use. I was going to run steel lines from the fuel filter back, but I don't know what to do about the rubber hoses which attach to the sending unit. Can I eliminate the rubber hoses (coming off the sending unit)? Or do I need to spend the $50-$60 on the rubber hoses at the dealership? Can I double-flare the steel lines like I have done with brake lines, or will they leak? The steel lines which go into these quick disconnect rubber lines aren't double flared...
I was hoping to buy some steel line, bend it, and replace the old steel line which was leaking. Now that I have the old line off, I'm kinda at a loss of what to do, what kind of pressure is in these lines? What kind of fittings/parts do I need to do this job properly. Any help from you guys on this basic job, that is now not so basic to me, would be greatly appreciated. Thankx. -Ice

Re: Fuel Lines
You don't really need to replace the hose... As far as the line goes, you're best off replacing both the fuel and return lines with the oem..While you could buy regular line cheaper, unless you have a proper bending unit (no Futurama Jokes please) you're better off getting the OEM.

Re: Re: Fuel Lines
I agree with Rlith in using OEM fuel lines..... I just hate using bender(small Joke) and screwing up the line. The other thing is your lines are carring about 65psi on the main line and about 2psi on the return line.

rlith
When you say you don't need to replace the hose, but just the line, how do I seperate the old hose from the steel line? I believe the replacement hose has fittings at both ends, while the original only has fittings at one end, and is permanently attached to the steel line at the other end. Also, I see no way of flaring the line to fit the hose. I wish the original lines were good enough at the ends so that I could just splice in new steel lines and reassemble. Even though they arn't leaking at the ends, I am sure if I put it back together like this, the ends will be leaking fuel by next week, just my luck. By the way, would a standard steel line double flared (like I would doing a brake line job), be sufficient enough to work on the fuel line? I am not sure of the pressure in the fuel and return lines. I got the return line off without dropping the tank, if I can get the fuel line off the same way, then I might just eliminate the rubber hose and use a hard line, I believe the only reason for the hoses is to make dropping the fuel tank easier and not really for anything else. If those steel lines can hold the pressure of the brake line, I would assume they could hold the pressure of the fuel line, can they? Thanks for the quick responce rlith, I appreciate it.

Re: Fuel Lines
The extra lines going back under the bumper are for the evap system. As to the rubber lines, just seperate them from the steel lines, no need to try to remove them from the sender unit. Don't splice, DO IT RIGHT OR DON'T DO IT AT ALL!

They don't seperate, they are all one piece. Thats why I was going to splice. I have to stop by the gm parts counter and see their diagram, the original steel lines and rubber hose are one unit, but I think now you can by them seperate. But I would need to buy the steel line and the hose, rust sucks. Does anyone know if it is possible to view gm's parts diagrams on the web to find out part numbers, like they do when you go to dealer? That way I could just call them with the part number and get a price.
