Gas Line Tube Bending

[M3Pilot]

Thinking of fabricating some hard fuel lines for the M2. I don't know much at all about how to do this. Any suggestions as to tools needed,good instructions on the web or other tutorials? Thanks

there is a tubing bender you can get from SO, MAC, or HF.
may also need a double flairing tool to make the little 'bubble' or ridge to keep the hose on

I have bent tons of tubing for the racecars

i have used the spring you find wound around brakeline piping with success in the past. course this was on mild tubing...........stainles anf the like would require a bender as previously mentioned........try a dry run using coathanger wire to get a rough idea before trying the actual piping.......the wire can be used as a template........little more time but worth the effort..........

If you run hard lines from the cell to the engine, be sure that you don't run the line all teh way to the engine. Between where the line is on the frame and where it gose to the engine, you need something flexible like Aeroquip or other rubber hose.

I use AN fittings everywhere I can.

Make sure you PRACTICE using a flaring tool and make sure it's a double flaring tool. The single flare is too weak and will leak! Making a template from mechanics wire is a good idea too.

One thing to keep in mind is if you are connecting AN or JIC fittings to hard line you need to use a 37 degree single flare (with the appropriate tube nut and sleeve) as opposed to the 45 degree double flare that e-tek mentioned which is common for standard inverted flare fittings. Just need to be sure what you are using first, then make sure you have the right tools. Good luck.

One thing to also keep in mind when flaring any tubing that has any length to it, is to make sure your flare nuts are on before you flare the other end Don't ask how I know this

Try Inline Tube.
They have pre-made ss line setups for just about everything. And what they don't have, they can usually make.

Unless you want to spend a lot of money on a quality flare kit that will work on stainless steel....let someone else do it.

I wasted about $50 in ss tube using a flare kit from Sear. It would have been cheaper in the long run to buy a custom made section from Inline Tube and then bend it to fit my jeep.

BTW...a good way to make a tube template is to use a piece of 12g solid copper wire...bend it to fit...then use that to bend your line.

just saw a neat looking pliers type bender at the eastwood co.........sorry not too savvy on this pc thing to post the link.........hell i have trouble with caps as it is.........

Do a search on eBay. There are over 100 listed right now. Saw some at five bucks.

Imperial makes the best flaring and bending tools in my opinion. Make sure you buy flare tool that rolls the tubing and practice your flares first.

The bending of the tube is pretty easy again I would reccomend the imperial stuff and some practice.
