Could someone go out to their car and take a look underneath at their high pressure fuel line on the passenger side near the swaybar mount.

I am changing bushings and noticed it looks kinked. Is this normal?

Mine has rubber lining on it now, I cut that plastic crap off and just ran some good fuel injection hose line from Napa. Its thicker and don't seem to do what your problem is at all. And its a lot easier to disconnect than those damn so called "quick connect" pieces of crap..

That is a bad kink!! The tube is plastic and shouldn't be like that... looks like someone moved it for some reason. It needs put back where it belongs to straighten out that kink, then held there with a bracket. I don't think it's permanent or damaged the plastic line, but I would keep an eye on it anyway. How long has it been this way? I'm suprised the car has been running right without getting good fuel flow...I'll bet it's been leaning out at high rpms though.

Thanks for your input, that was my thought also. Not good thats for sure.

"How long has it been that way?" Not sure, I've only owned the car for about 2 years, but it's been an ongoing process to get the car running properly. Previous owner

Oh and BTW, your black Capri is sick!

bad

Well looks like its been kinked long enough to where that plastic line is not gonna go back to shape. I straightened it out as best i could and ziptied it but it's still kinked.

I see no easy way to replace that line either... just continues waaaay back as far as I can tell. Looks like the plastic is formed over the metal, I am not sure how to replace just that section. Fuel pressure is where it should be but I get a lean pop through the intake sometimes as I take off from a stop light, I wonder if this is the cause..

So then you just slipped rubber fuel line hose over the metal and used hose clamps or what? I'd be worried that might leak at some point...

Looks like it's the return line. If it's the smaller of the two lines you may be able to get away with putting some fuel line in place of it.

I just replaced my fuel lines. I did it with no rear, exhaust or trans in the car. With them in, it's a huge PITA.

You could always try to hold it externally with heat shrink or some sort of clamp so that it maintains it's shape

Thanks for the input. The line says "High Pressure" so I am guessing that it's the feed line from the pump.

It's straight now, but it still is kinked, the plastic wont go back to its original shape.

There has to be a way to repair the line, I am just not familiar with exactly what the proper way to do it is.

Ya, have never had a problem. They also have a special hose clamp for fuel injection so that it don't have a pinch spot or something like that. Been running that way for about 5 months and no problems.

Well, they both say high pressure. It's the hose. It's rated for high pressure.

The smaller steel line is the return line.

If you can somehow form it to it's original shape and hold it artificially, it may eventually remold with some heat and time. Question is how to hold it. Could always get a small coupling and hold it over it and clamp it?

You could try a heat gun to soften up the plastic and work it back into shape with your fingers then let it cool down while holding it in place, then clamp it to the body to hold it there permanently. I would do it with the car running to let the pressure in the line work from inside to help you. Just don't melt the line or gas will come squirting out and ignite from the heat gun. heck, yo gotta replace it anyway if it doesn't work, so what do you have to lose? Just a thought.

better

I picked up some 5/16" rubber high pressure fuel line and some fuel line duckbill clamps.

I only had a few minutes last night to work on it, but I did try a heat gun real quick and was able to get it better, still slightly misshaped but a lot better than it was. I am going to give it another crack with the heat gun and if worse comes to worse I will take the plunge, cut the line and replace with rubber.

Thanks for all the input guys.

You'll need to get the gas out of the line and then heat the line until you can take a pair of pliars and manipulate it back into shape. You can heat it on the car with a blow dryer. I replaced my fuel lines at the tank and I had to heat the hose in boiling water before I could get it to stay in the proper shape.

As posted above, Rom Morris has the correct fittings and hose. That's where I got mine.

You can use FI hose. Make sure it's American made hose and double clamp it with FI clamps.
