Help..Factory fuel line to AN fittings/regulator/rails etc..

96UAV · Post by **96UAV** » Sun Feb 26, 2017 6:56 am

Trying to figure this transition out but keep running into dead ends and fittings that don't work. For those of you who run aftermarket fuel systems (at least on the engine), how do you make to change from factory lines at the firewall with these fittings

To AN style and run your aftermarket regulators and rails?

I've tried a couple fitting options but I can't seem to find a quick connect fitting that attaches to the factory fitting and transitions to AN. I'm thinking I'll need to cut the factory fittings off and install something like this?

I appreciate any feedback or pictures.

This is what I thought...but the oem fittings at the firewall are male and the fittings I need have to be female quick connect to AN..I've actually bought the russell and aeromotive fittings already and they aren't the correct quick connect female fittings.

This is the one you need for the fuel rail

The stock braided lines use standard male fitting adapters can't remember what size. I'll see if I can find my receipt and give you part numbers.

That looks like it might be a winner. I'm starting to think I'm doing something wrong...it seems the aeromotive options I've received in response is what others have used but I don't see how that will fit the application. After removing the stock fuel rails (with the motor), all I'm left with is the feed and return at the firewall.

Those fittings are male and look like this:

Does the Earls fitting just snap onto this?

Yes that correct

The Earls fitting referenced in the email above *may* snap onto the gold fitting pictured in your first post. I say *may* because the Ford fittings are usually a little different, i.e. the distance from the end of the tube to the flared section is longer than what the fittings will work on - most of them are designed for GM LS1 fuel line fittings.

To adapt what you show in your last picture, you'll need something more like this:

if I'm understanding your connundrum correctly (I went through this a few months ago on some similar Mustang fittings).

The Aeromotive adapter took care of one of the fittings for me. The other one, a 5/16" line, I believe, required a more creative, 2-adapter solution.

If this is what you're after, I can dig up the pieces tonight and let you know PNs.

That'd be great! I've found both the 5/16" and 3/8" Earl's fittings referenced above and have them sitting in my cart with Summit. Still worried they'll be another $60+ set of fittings that won't be what I need. I feel there should be a simple solution as many folks have built motors that surely required updated fuel systems (at least on the motor side) but I've come to dead-ends.

My last resort would be to cut the factory fittings off the line and use a push style to AN and hope that won't eventually leak.

You will be good with those. I have -6 ones that I took off my bronco for the new motor if needed.

"good with those" meaning the Aeromotive or the Earls?

Either brand but I was speaking to the sizes.

OK, finally had a chance to take some pics last night. I re-read your thread and yes, you're looking for the fittings that I was looking for awhile back myself.

The Aeromotive fitting I linked above works for one of them:

https://www.aeromotiveinc.com/product/f ... 6-an-male/

The other one was a combo of two pieces: a spring-lock to -8 male and then a -8 to -6 adapter. I forget the brand of these two pieces but they were probably Fragola or XRP.

Also a photo of two adapters that a friend made for me that accomplish the same thing.

I'm also attaching a photo of the male fittings I was trying to adapt to for reference.

Todd,

Thank you for your time and assistance! I was at Ramjet yesterday trying to figure this out and it seems even they were puzzled about the fittings required but I think between the info here and what I figured at Ramjet I've found a solution...I hope. I'll update my build thread eventually. I'm sure there are others who've encountered this issue.

Finally figure out a solution and seems to be the easiest and cheapest. The hard-line sections after the filter that run up to the firewall is where I made the transfer to AN. There is a compression fitting that uses a brass crush sleeve that slides onto the hard line and screws together creating the AN male threads to run braid from there.

I'm going to move the clips further in on the bracket to secure them back down and done.
