I'm about to attempt my first braided fuel line install, so i ordered all the fittings and hoses, but i'm not sure how to install the fittings on the lines. Are they pressed on with a special tool? :confused:
 
Depens of which fittings you are using? Are they going on braided lines or ruber composite push on?
 
Using either a soft jawed vise or you can wrap the fitting with tape to prevent scratching,thread the big fitting over the outside diameter of the hose. It will stop turning when you have reached bottom. You can also look inside the larger fitting and see where the hose will stop.

Now,LOOSELY put the hose and fitting in a vise,taking care not to scratch it. Mark the braided hose with a Sharpie right where the bottom of the larger fitting and the hose meet. This is just to make sure you aren't pushing the hose out. Take the smaller fitting and liberally coat it with some type of lubricant. Aeroquip make assembly lube or yo can just use silicone spray. Insert the tapered end into the hose/fitting. Screw it in until it bottoms out all the while making sure the hose is not being pushed out. It will get very tight but have patience.

It might sound hard but it's really quite easy. Make sure to wrap the hose with tape when cutting as this will help decrease frayed ends.

DUH i just noticed you said braided line...
 
I like to use masking tape to wrap the hose when cutting it to length. Some use duct tape or electrical tape but I find the masking tape easier to work with. It makes it easier to slip on the large nut on the hose because the tape is thinner.

Also what are you going to use to cut the hose? A chop saw would be easiest but I've used an angle grinder with a cutting wheel with great results. I've used a hacksaw once but it came out like crap.
 
i found the best way to cut the hose is with a sharp chisel and a 5 lb sledge.

If you are serious that sounds like a pretty good idea for those without an air compressor.

it works much better than a cutoff wheel. no frayed ends and no debris inside the tube.

It's the best idea even when you have a air compressor! Tape and mark the place you need to cut. Use a metal block to brace the braided line. Sharpen the chisel if needed. Use a little oil to slip the braided line onto the fittings. Don't forget to buy or borrow a set of aluminum wenches. Don't forget to purge the system before you start the motor.

I think he means to flush the lines of any debris. There will be some trash in the hose so just squirt some oil or, I may be wrong, some brake clean to flush it out.
 
I figured your Local Speed Shop should be able to help you out. :) I have shown many a customer how to do them. BE careful of the small pieces of braid. They are like little needles and they draw blood :eek:
Good luck :)

Flush with your filter or filters inline with gasoline. Any debris contained in the lines will be in the filter(s).
 
The way Walton does it is exactly how ive done it and i have not had ONE leak... ever. I usually cut out some strips of paper to protect the fittings from the wrench and vise. Do not ignore the marking step... otherwise you will not have any indication that the hose was pushed out. Oh and the best tape ive used is the fiber reinfoced stuff... its clear with white fibers running with the length of the tape.
