recommendation on PTFE lined fuel line with Aeromotive Fittings

[72Z/28]

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.

[GregWeld]

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.

I assembled ptfe power steering hoses no special tools but i only had to do 2 ends,those tools would make fingers thankfull and swearing and gouged knuckles down to nothing for a full job :bang:

[GregWeld]

Here's how I do this.....



I have a real nice hose slicing blade --- Here's the model number of it...


I bought mine from XRP -- it's their part number 329003

I have a fancy dandy hose holder and saw set up ----- but you could just make a crude "miter box" with a slot in it....

The blade..... a meat slicer!

Here's the difference between a cutting tool as shown in the videos..... it SMASHES the liner!!! Not good -- doable -- but hackey motto style! VERSUS the slicer blade with doesn't melt the PTFE or deform it in any way!

I use the olive tool to spread the braid....

Then use the same tool to insert the olive....

And you can not do without these SOFT JAWS....

I agree GW, having the proper tools is the way to go..But some of us don't have these fancy tools ;). If I'm using the reusable fittings I take a hand held thin cut off wheel, masking tape and deburr with a sharp counter sink or knive and been making my own PTFE brake, fuel and high pressure lines for years, (all though I do end up with lots of lil holes in my finger tips) . Or I go to our local hose shop and pay them to crimp the fittings on

PS where do you get your nails done?? And must complement you on the very nice clear pics :hello:

I actually just installed this tank in my '69. You only need to use the Aeromotive O-ring fittings (6AN male-to-male) to create the 3 male 6AN outlets on the sending unit. Then you're free to hookup whatever set of 6AN PTFE female fittings and PTFE hose that you like to those 6AN male outlets. I think I went with 1 straight and 2 45 degree hose endings. You just have to make sure that you match the manufacturer of your PTFE hose endings and PTFE hose. You can't mix and match on those. I found Earl's PTFE line(teflon inner liner, static dissipating) and PTFE fittings to be the least expensive, but their hose endings are a bit of pain to install. The Aeroquip line and hose endings(Super Gem) are actually less expensive and easier to install, but they don't have the inner liner so it shouldn't be used in long lengths. Now, if you're looking for black PTFE hose and fittings, that's a different story. That gets pricey. I used 'reusable'(non-crimp) fittings and just a cutoff wheel and a vice(and some electrical tape when cutting and water for lubricant) to create all my hoses and none of them leaked with the exception of one Super Gem fitting that had a manufacturing/maching defect in it which I replaced. Takes a bit of time but nothing heroic.

I guess I am going to use the existing push on type end hoses to avoid going through the hassles with the PTFE end fittings.
