recommendation on PTFE lined fuel line with Aeromotive Fittings
 

Hello guys

I bought the new Aeromotive Stealth EFI fuel tank along with their Fittings, and now I need to get my fuel lines replaced.

I have read good things about PTFE lined fuel lines like Pegasus..

I would like to get Pegasus PTFE lined ones but as per their instructions I must use their fittings as well.

My question is what other alternative PTFE lined fuel line can use with the Aeromotive fittings that I have bought already?

I appreciate your input guys

Do you plan to make up these lines on your own?? Have you done it before?? These are difficult to do -- I do them all the time -- but I have a special saw... and I have the insert tool etc.

It's not rocket science but it is a "process" that is more difficult than other types of hose/hose ends.


Aeromotive has PTFE hoses and ends as do several other manufacturers. You can also usually find these hoses and ends (although they call them JIC rather than AN) at hydraulic hose shops...

Remember to index the ends... as these don't swivel!

I'm doing the Pegasus lines....they are frickin expensive....but they are easy to work with...no special tools or special saws etc.

You don't have to use the Aeromotive ends on their pumps etc...any AN hose fitting will work....you just have to have the ends and the hose be compatible with each other.

Maybe return the Aeromotive ends?

Agreed... Although the Pegasus lines seemed less expensive to me than the other options which I looked at. We assembled the Pegasus lines without any special tools that I recall. Turned out well, and no gas smell so far. :)

It's not about the ENDS fitting other ends --- a -6 AN is a -6 AN.... but the HOSE diameters (outside) ARE different between different manufacturers... and that's where a problem can come up.

Normal AN fittings will not work withe the Pegasus hose, it uses spacial fittings.

Like I said.... the hose and the hose ends have to be compatible with each other..ie the Pegasus hose has to use the Pegasus ends..... Earls hose has to use Earls ends etc etc....

The male end on the EFI tank doesn't make a difference....so you can have an Aeromotive male end coming off the tank and use any AN female end on any hose...but the hose has to match the hose end used....

That's what I said :)

And you're absolutely right!

That sucks because now I have to ditch the Aeromotive hose ends if I am going to use Pegasus PTFE hose.

As far as the installation I have gone through their instructions and they do not recommend to use a special tool.

When I said I have tools for these kinds of lines ----- I have a saw that has a blade that resembles a meat slicer... it cuts the SS braided cover and slices thru the liner without deforming it or melting it etc... it makes a perfectly nice squarely sliced "end" of the hose....

Then I have a tool that takes the olive and inserts it (the olive goes between the braid and the PTFE liner). You first put this tool in the hose end - which slightly expands the braid -- and also smoothes out and slightly (as in extremely slightly) opens the end of the PTFE... then you load the olive on it and push the ferrel onto the end of the hose.

These are not complicated tools...

Here's a how to video:

Personally this is how a hack would do this kind of work... I was STUNNED that anyone would actually make a video showing such CRUDE workmanship... but it does discuss some critical steps... particularly the way the liner needs to be smooth INSIDE after the olive is inserted -- because to me == that's the hardest part of doing this type of hose.









This is another video on assembly -- and again -- it I was this much of an amateur at hose assembly I'd quit the hobby... but it still gets the average guy an idea what he's dealing with.
