Advice on broken fuel line

[juntjoo]

so as you can see I broke the fuel line replacing the fuel filter and just want the simplest solution. Reading up on this issue I've learned there are common upgrading options usually consisting of the braided ss lines with higher flow fuel filters but I don't necessarily need that right now as much as I just want to get this car running again, so is there a way I can fix the end of that line back onto the butt of this new stock fuel filter(same as the used one in the pic)? What is my simplest option(s) save for replacing that whole line which looks like a real PITA. Thanks.

That is why you get a wrench on the filter also and you won't twist the line off. For fixing it you have a few options. Steel braided from the tank as stated, or you can replace the damaged line with a new line and connect it to the existing line under the car.

Yea no easy way to fix that. I dont know if you could use a compression fitting or not, but dont see why not when they are sometimes used for braking systems, and the fuel system will never rech those kinds of hydraulic pressures.

You can use a compression fitting but do not use one from the likes of home depot. Go to a fitting shop and get a steel fitting. Easiest route is to go to the scrap yard with a tube cutter and cut off the piece you want. I did it somewhere after the first curve under the filter. You can take the entire filter etc then you can take it off at the bench. You would be able to slide a box wrench over it now since you have the line cut. Tell the fitting shop what you're doing and they can sell you what you need. Take the salvage piece of line with you. Don't forget to have the nut on the line when you assemble it and have a fire extinguisher nearby for the first startup just in case. Easy fix, honestly. Just a PITA to go gather what you need.

You can also get brass fittings by Edelmann or Dorman at nearly any parts store.

Youll need something like this, but a bigger size so ill post a couple links to give you an idea of what youre looking for, and some possible sizes

Dorman Products - 785-304

Dorman Products - 262B

Dorman Products - 490-025.1

Dorman Products - 62F

cheapest is find a donor car and try not to break that one, easiest is STM: -6AN FUEL FEED LINE KIT (FILTER TO RAIL) | 90-99 DSM. way less headache, plus it's an upgrade.

 

[bastarddsm]

Cut off the mangle portion, and re flare it.

Thats what i did when it broke, works fine now 6 years on the 1g and no problems.

Incorrect link buddy. He needs the one going from filter to fuel tank.

^^Probably the best bet unless you have the cash to replace the whole line from the tank...

Yeah, I used another wrench but it was still too tight apparently. And at first I didn't have a line wrench so that might have made things worse as you can see with how eventually the 14mm nut got rounded.

Thanks for the replies. I'm going to just reattach it with a compression fitting, though what is "re-flaring"?

Cash isn't the issue. Its time. Unless someone can tell me different it looks like replacing the whole line would take a longer time than just putting in a fitting. wouldn't I have to take out the fuel tank to get to the end of that line? and it doesn't look like it would be easy to get a new line in especially where it has to curve into the engine bay. Looks like a lot of dangerous line bending.

Wow, thanks, but that looks like the same amount of work as just replacing the whole line. is this "flaring" absolutely necessary before attaching fittings? If so maybe I should just upgrade the whole line then no?

check that link I posted, Its just from the top of the filter to the fuel rail. it comes with the adapters that you screw to the rail and the filter then it attaches using -6an fittings. its pretty straight forward

 

[juntjoo]

I'm not going there though. I'm fixing between the filter and the fuel tank. That line there is basically cut, just under the filter. Thanks anyway. I'm about to head to the stores with my parts, see if I make it back with the right stuff...

So check this out. I found this fitting with a ferrule

that goes right into the stock filter as you can see, and apparently I'm supposed to put the end of my broken line into the back of this nut?

Here's the back of that nut.

so the line is supposed to fit INSIDE the ferrule?

[dsmcarnag3]

my fault, thought it was the top to the rail...I'll shut up

 

[bastarddsm]

Nope. That piece of shit will leak.

Do what I told you. Cut off the mangled portion, slip the old tube nut over the line, then put a double flare on it.

Worst case, you might have to finagle with the filter bracket to get it to mount a bit lower, but at least it will be fixed right.

 

[pauleyman]

That isn't right. If you lookup that fitting you'll also find this.
"Not recommended for use with steel tubing."
The two options you have at the engine bay are reflare or get a piece from a salvage car and use a double compression fitting. As I stated above use a steel one. You can find one at a fitting supply house. NOT at home depot. Even if you got that to fit that isn't a flare tube nut on the filter side.

I'm begging you. Do this right or buy a good 10 lb fire extinguisher for your first drive.

 

[juntjoo]

Okay, I saw that too. So this line is steel uh? For some reason I thought it might be plastic. hey, so do I need to worry about pressure rating? is that something normally mentioned in the specs of parts?

I went to Lowes BTW, but close enough. but I could be wrong because I went to both actually and two auto parts places both of which had "compression unions" or fittings, but I wasn't quite sure how I was going to use them. And the guy at the Lowes depot said that this fitting I got flares the tube, or line, when you tighten the nut. But I'm guessing you're stressing I need steel because the line I'm fixing here is made of steel and it needs to be at least as strong? Does the pressure rating play into any of this here?

Oh, so you're saying that the end of that home depot fitting that screws into the butt of the fuel filter isn't sealed?

That particular one might leak cause its meant for nylon tubing, but the 4 that i posted will not as they are made for steel tubing.

Correct.
