FUEL FLEX HOSE KIT

[rednotch]

Not crimped, run a razor up the Barb and peel it off, lrm directions even states that in the directions with thier kit step 5 & 6. https://latemodel.cachefly.net/downloads/instructions/LRS-9964B-K INS.pdf.

the tether saftey clips you can still buy, they come in singles or a boxes of 25 all fords had them for that style connector. https://www.ebay.com/itm/2548547643...pid=5335821607&customid=&toolid=10001&mkevt=1

Feed is the line with the Schrader valve on it so just trace it to that.


The hard line to soft line joint from another thread without all the grim on them, it's just a pushed on barb ,that is how tight nylon hose fits them, you can use 360* fuel pinch clamps if you want with nylon repair hose but most don't have the tools and its not needed.

Avoid grease on fuel lines o rings, fuel isn't going to break that down fast and can plug up the regulator and injectors. petroleum jelly pretty much melts when it sees any heat and gas will break it down fast, you only need it to lube the O-rings for install.

If you want braided, you need to cut and flare the hard line, buy fittings and make lines or run an all braided kit. There is no adapter that goes from a barbed hard line to a AN fitting. The pre made stuff plugs into the female fitting at the end of the factory soft line on a fox body.

In your fuel line pointer picture, where do those lines run? The fuel line safety clips are stock. I had as much trouble installing the new spring lock quick disconnect lines as you did removing yours. I ended up using wheel bearing grease to lube the O-rings and inside where they slide in.

The lines run back to the tank and connect forward to the fuel rails.

Thanks for all the info! The kit is coming today.
Can I use silicone dielectric grease on the O-rings?
How hard do I tighten the hose clamps. As tight as possible or is there a happy medium like snugging them up just enough, like you would in plumbing?
I did use a razor. Vertically sliced the lines and peeled them off. It was easy. In the pic that has the red line pointing to the flat spot on the line. It was below the barbed fitting, which I could see when I peeled it off.
I think I'll go with all braided next.
Thanks again!

I usually just use WD-40 on O-rings to make sure they don't bind up during installation. Maybe someone else can weigh in on this if it's not best practice.

I would definitely go with the "happy medium" tightening of the hose clamps. The strap will deform and strip out if you over tighten them and there's no need for them to be ultra tight to make a good seal.

You can use WD-40 but a petroleum based jelly as rednotch mentioned is probably your best bet. I work in oil and gas for a refined petroleum products pipeline and that is what we use when we lubricate o-rings on instrumentation.

Finally got the fuel lines installed. Thanks for all the help from everyone on here!
Hers's some tips from the mistakes I made that I'm going to pass along so no one has to go through what I did! I wasted 3 cut to size lengths of hose. Good thing they give you a generous amount of hose.

1- When you cut your lines to length, Attach two hose clamps in the middle of each hose facing in the direction that you want them. That way you won't put the hose on the barbed fitting and then realize you forget the clamp. That hose isn't coming off unless you slice it with a utility knife. If you do have to cut it off, make sure you don't cut into the steering rack boot like I almost did!

2-Do the lines going back to the gas tank first. They are the hardest to get on. I lubed the hard barbed lines with Lucas Oils Fuel Treatment. Take the cap of a water bottle, pour some of the fuel treatment in, then use a couple swabs together to lube one fitting at a time.

3- Wash your hands if you get any grease or oil on them. You won't have a good grip to push the line on.

4- Have 1 swab ready sitting in the fuel treatment. It's for lubing the inside of the hose after you heat it.

5-Then you have to heat the end of the line with a blow dryer. It takes about 5 minutes to get them hot to the touch. I wouldn't use a heat gun. There's a
chance they could melt.
I couldn't get the hoses all the way seated without heating them. I had to cut them off a couple times when I was just using the lube.

6- When hose is hot enough, quickly put the fuel treatment in the hole of the hose and coat the inside.

7- Get under your car as fast as possible without knocking yourself out and push the hose on firmly. It should slide all the way on.

8- Slide the clamp up and tighten it up.

9- Repeat the steps for the other one next to it.

10- The connections from the fuel rails go on easier. They didn't require heating. I just lubed the barbed fittings one at a time. And lubed the inside of the hose. They slid a lot easier than the ones going back to the gas tank.

11- Don't forget the fuel safety clips. Mine aren't on in the pic for a better view.


I hope this helps anyone doing this Fuel Hose Kit. I chose the Lucas Oil Fuel treatment for lube because it's made for the entire fuel system. No contamination.
I recommend lubing one barbed fitting at a time. That's so when the lines are so close, like the ones going to the gas tank, it doesn't get on your hands and the outside of the line that you are pushing on. Also, put the clamps smooth side back to back to prevent damage to the hose.
