An fittings for Nylon Fuel Line

[Dan Babb]

Searched online, but not finding what I think I need.

I currently have nylon fuel lines connected to the stock ford rail. It's using the stock style fitting to connect to the fuel rail.


Going to install a MassFlo setup. the manifold I have already has a pretty cool mount for the Fuel Pressure Regulator on it.

Intake:


Closeup of regulator:



From what I can tell...the fitting on the backside is the return (it has a bypass sticker on it). The fitting on the top (blockoff plug) is for the fuel inlet.

I'd like to find some AN fittings that will connect from my nylon fuel lines right into the fuel pressure regulator. Do I need any special type of AN fitting or just one with the 3 barbs on it and of the right size?

The fuel line setup is the Ron Morris performance kit...what size AN fitting do I look for that will work?

Looks like -6 to me, but in that size SAE and JIC are not compatible. The brass ones are probably SAE 45deg flare and the steel ones are probably JIC 37deg.

The pushlock fittings with 3 barbs and a yellow ring on top are designed for pushlock fuel hose and is generally about 300 psi.

Your local Hydraulic hose shop should have what you need.

Dan:

What nylon lines have you got? Are there really nylon lines running to the fuel tank? If it is hard nylon, there is a type of compression fitting that you can use but it is not 37 degree. It is similar to the compression fittings you have on your manifold there which are 45 degree tube fittings. Those can made to work with nylon. There is a small thin wall reinforcement that goes inside the nylon line and compression ferrule that fits around the tube when you tighten it. If the nylon lines you are talking about are soft nylon, like tygon then you can use barbed fittings. If it were me I wouldn't use nylon lines for anything where there is any heat at all.

The fuel lines I have are shown here:

Ron Morris Performance: FFR COBRA Fuel System Kit, Complete

I used it on my last car and a lot of guys have used this kit on their builds. It's a hard nylon line. The kit comes with the push in fitting to connect with the stock ford rails.


Ideally, it would be nice to find something like the fittings on the end of the stock fuel rail (like the picture below), but with pipe threads on the end...then I could plug this into the FPR and be good to go.




I'll take some pictures of what I have to a hose shop and see if they have any ideas that can help.

Aeromotive has close to what I need.

They have a good fitting for the return line.



But the feed line has an extra port that needs to be blocked off (which I could do, but it's another spot that could leak too)


It also has a port where I could put a fuel pressure gauge (assuming I'd have room for it).

I'd just need the two NPT male -> AN Female fittings to make this work.

[QSL]

yea, for that stuff you will need compression or push to connect fittings. Hose shop should have both. But chances are that they will only have them going to male pipe threads.

I used something like this for my Ron Morris nylon lines.

Not sure if this is the exact one I used... been awhile, but you get the idea.

I can email you some pics if you like.
