Stainless steel fuel Lines and AN fittings.\

[Flybiyou]

I just got in my FPR and the line to put it together are a PITA. I cant seem to get it in the fittings. If you look in the fitting there seems like some kind of step and the line wont go past it. I bought the feed line and FPR install kit from Slow Boy Racing and this sucks. Can I wrap a piecie of tape to help with the fraying. Any other ideas or helpful hint's would be great of you to share.
Thanks

there are threads on this, most people wrap the area to be cut with electrical tape and then cut it with a high speed cut off wheel such as a dremel. also putting alittle bit of wd-40 or a drop of oil on the tip off the fitting will help it slide on. Yes they are a PITA but once you learn how its easy.

Get a chizel and Hammer. Put electric tape over the part where you need to cut. Put the chizel over where you want to cut, hammer it and it should cut it in one blow. Take the tape off (or you can leave it on) and push it into the fitting end. Then bash it on a counter top to where the line will meet its stop point in the fitting, the little ledge you spoke of. Now take the other part of the fitting and dab a little bit of oil on the tip of it, push it into the rubber and start threading it in. It helps to put this in a vice when you are doing this so you can put some pressure on the SS line so that it wont walk itself out of the fitting as you are tighting it. Have fun.

First off...DON'T USE A CHISEL!

Get some reinforced tape and wrap the line were you want to cut with the tape centered over the cut. You can use a hacksaw, although I prefer a Dremmel with a new cutting wheel or a 3" cut off, and cut the line being careful not to fray the braid.

Remove the tape carefully as not to fray the braid, put a rag on the garage floor with a wrench that will fit on the hose end. Put the hose end in the fitting and you have to roll the hose into the fitting and twist and push the hose in at the same time. The floor and your foot on the wrench will give you the sturdyness on the fitting to get the hose in.

Dab a little oil on the second part of the hose fitting and screw it in.

Install the hose at a slight angle in the fitting and just twist and push at the same time, it is actually easier than it sounds.

The biggest key I have found is getting a VERY CLEAN cut. Dremel with a cutting wheel at high speed works the best for me. Any fraying whatsoever will make it a major PITA to get the hose in the fitting. If you don't get a clean cut the first time, retape a little further down and do it again. It will make your life much easier in the end.

There are many threads on the topic of cutting and installing stainless braided hose and AN/JIC fittings.

Why not ?

 

[FORMONTOYA]

The average chisel is not sharp enough to cut the small SS strands in the braid clean enough for this process.

Not saying it hasn't been done, but it will be a pita without a new, sharp chisel. Be a lot easier with a Dremmel or 3" cut off.

Just so you know, i didnt use the sharpest chisel in the world either. It did a clean cut straight threw. Just had to do a couple of blows. Just make sure that you place the hose on something that isnt going to move, you dont want it to soak up the blow your about to put to it.

Well I got it to work finally once you get the first one you get a idea of how to do it. I broke a fitting though and I dont understand why though. I was tighting the male piece in and it was getting tight to turn but I thought the two halfs are supposed to met. Now I have to get another fitting and hope that I can get that piece that broke off out so I dont need more SS line The other fitting's that are on the lines are tighten down but have abut a 1/8 showign between them. There tight I have pulled on them to see if they move or come out and its fine. I just dont feel like breking another fitting.

The last thing that is killing me is were to mount this thing. I have searched and found alot of 1g's but all the 2gs Are far away pics not good enough to see how the lines were ran.

Thanks for the help

Bolt cutters work wonders, they even sell a set for cutting stainless braided line in SummitRacing.com.

If you are careful, installing fittings becomes easy. Patience is a plus.

You arent the only one who broke one. I got a kit that uses goodwrich fittings, man what a pile they are. I broke one barely putting any strain on it. I then bought a Aeroquip fitting, these are nice! Ive made 2 different lines with the same Aeroquip fittings, they have held up great.

I just got done doing this on a 2G. I went from the pump to the rail, with a areomotive fuel filter. All my hose ends went on easy. I used a cuting wheel. This was my first time using steel braided lines. I just followed the stock hard line. I just used alot of zip ties to mount the line to the stock line. For the fuel filter I used a piece of 2"ID silicone around the fuel filter and put it in the bracket that holds the stock filter. I used justed 3 straight fittings and 1 90*, with 15feet of -6an hose. I didn't even need 15'. I could have used 10', but if I would have messed up on some cuts there might have not been enough. I have alittle over 6' left. I am using summit brand fittings and hose. I got the black anodized fittings. The summit brand fittings are way cheaper that any other brands.

The reason you broke the fitting, is because threads were contaminated and locked up. Aluminum is tricky like that. Make sure you lubricate threads before putting the fitting together. A spray of WD40 works great. Another reason some people brake fittings, is when one of the steel strands from the hose gets caught in the threads. Make sure none of them steel hairs stick out into the threaded are. Yet another way to brake a fitting, is to apply tightning force (unintentionally of course) in direction other then in plane, completely perpendicular to the fitting. Some fittings are easier to break then others.

As far as cutting, masking tape works much better then electrical tape. Plastic gets hot from cutting, and becomes soft, alowing braids to spread out. Paper, on the other hand, tays nice and tight. Oh, and never put taped end into the fitting. Always remove the tape.

I lubed the pieces up before I put them together I think the fittings are cheap. GOODRIDGE
I have the pieces about 1/8 apart from full close if it leaks I will tighten them but I dont want to break another one. For the one I broke I was thinking about buying a barb fitting that will screw into the fuel filter 3.00 compared to 20.00 for another 45 6an . That is if it will hold. Does anyone see this as a bad. I have seen other peoples FPR setups and it seems they all used barb fittings. I dont see it being any diffrent than putting one on top of the filter. If it comes down to it I am just going to hook the stock feed line back up. After seeing how small it is I really dont want to put it back on.

I wrote a tech article on the feed line part if this helps any.

As for the fittings, Aluminum 45* fittings from Earls/Aeroquip/Russell are way less than $20 at Summit (hell I got one locally for $16). The SS fittings are only needed if you are running alcohol from your tank. I assume this is not the case?

Make sure you're using the right size/type hose for the fittings. Also, applying a bit of lite tool oil to the fitting that screws into the hose end (the part that actually goes inside the hose) really helps getting thee two parts together.

Oh, yea. Cheep fittings are just that. I gambled on a 90* Summit Brand hose end and ended up being defective (the seal in the hose-end swivle). It's bad when 65psi of fuel gets sprayed inside a running engine Luckily I found it in time.

The Russell hose ends are "flared" out a bit on the piece that the SS hose goes into so is MUCH easier to install.

Dont' give up, the end result will be well worth it

ditto. Summit swivel fittings had me hunting for a fuel leak for a while (it wasn't spraying, but dripping nicely). Although I think their standard non-swivel fittings are very decent for the price. Didn't brake any yet, or had any troubles with.

I found this site today, its gives some good info on cutting braided line and some cool products for assembly of lines and fittings. Enjoy!

First off I have no experience with this tool, but I do have experience with SS lines and an fittings. Check it out and if anyone buys one and uses it write a review on it. It makes ss line assembly look easy.

Holy crap $75 for a piece of plastic to hold the hose end WTF

I've done this dozens of times just wrapping the hose end in cardboard, placing in a vice and twisting the SS line in. A little light tool oil on the hose end's "cutter" threads and is easy as pie.

FYI. I found that Russel brand hose ends have a slightly larger diam inlet making it much easier to install even frayed SS line into
