Engine/Transmission (1998.5 - 2002) If YOUR thinking about -AN style fuel fittings.......

[Walt-L]

This is just a heads up on what happened to me when i trashed all the banjos in lew of straight -6 AN fittings with SS braided fuel line. After 6 AN flare nuts were tightened down on my new system, I found I had a leak off one of the straight fittings. I called customer service to the outfit of these fittings and they said typicaly the SS hose sometimes backs out of the red nut when you start the threaded barb into the nuted hose. OK so now I needed a new 3 inch peice of hose. Had to buy 3 feet of hose again cause thats the shortest they sell. They did give me free S&H on the new hose. Come to find out after taking the bad fitting apart, the hose didn't "slip" back out of the nut at all. The flare face on the fitting had chatter marks all around the concave face of the sealing surface! So, I thought good thing I bought a extra -6AN straight fitting, Ill redo it with that one... . NOT. It also had a few chatter marks on the sealing face. All tho not nearly as bad as the leaker I took off. I ended up making a aluminum mandrel in the lathe with a 37. 5 degree point on it, stuck some stick um 320 sand paper to the point and spun polished the chatter marks down just enough to break blue anodizing off the hi chatter marks. Reinstalled the new fitting and I im drip free! The morel of this story is ALWAYS check the sealing flange inside the nut BEFORE you assemble your new line system. Granted it was only a $4. 25 straight fitting but here I sit with #2 Oilhammer colone on once again!!! The guy at VERY popular race eqip catalog said I was THE ONLY ONE that has ever gotten a bad fitting in his 19 years with the company :-{} . If YOU happen to be the second guy in the world to get a bad fitting like me, Please chime in here so I don't feel like a freak of nature !!!

I'm guessing these were Russell fittings? NOt all AN fittings are created equal-- Aeroquip is best, followed by Earl's, followed by Russel.

Since you asked, Summit hose and what I "thought" were aroquip fittings with Summit names on them! Oh, The customer service guy did say Summit is always sourcing new distributors. Now don't get me wrong here, Summit is a great outfit and they have always provided me with a great selection of quality hardware in the past. And their shipping is lightning fast.

I used Earl's -6an on all my fuel lines. No problems at all with the fittings or the perform-o-flex SS hose. Top notch!! Thanks for the heads up!!

I've seen people mix up JIC and AN fittings.



They have a different degree of angle. One is 37

 

[Hohn]

I'm pretty sure that both JIC and AN are 37 degree, and it's regular flare ends that are 45. I'm not sure though. I KNOW that AN is 37, and I've seen listings in Northern Tool for 37 degree fittings listed as JIC.

A few times the folks at Aeroquip have asked me about the angles and showed me a bunch of fittings and if you did not look close enough, you could not see the difference. You can even thread them on my fittings... but of course they will leak.



Justin, I will see if I can bring a couple down to Cheyenne so we can 'examine' them.

I got my Aeroquip fittings from Scotty. The flairs looked pretty smooth to my untrained & aging eye. I did have to snug things up several times to stop a little weeping. I was being cautious not to over torque those brass threads. They sure do make it more difficult to draw the fuel pressure down.

Don't forget the hose for the POwerCore BHAF

any one on hear feel like posting a part # list of good fittings for a big line kit summit has aroquips and always had good service with them (summit) fast shiping good easy returns and good tech support. TIA

Rivercat,The place to start is the banjos, To get rid of all of them you will need the Alumimun AER-FBM2116 fittings. This is a 12mm X 1. 5 thread on one side (IP,Fuel Filter and Lift pump ports) and -6AN on the other end. There is some kind of o ring that gos over the 12mm thread but I don't know that PN. These fittings are $9. 50 in Summit with out the O ring. Personaly I sent them back because the neck walls on the 12mm side are only . 040 thousadths thick. Instead, I picked up 5 STEEL Earls EAR-961606ERL fittings that are -6AN X 1/4"NPT. I turned the 1/4 npt side into 12MM X 1. 5 threads. Now I was able to use the Cummins Banjo bolt washers for a perfect TIGHT seal and fit(you can't use these washers on the Aluminum ones). See my gallery link to see some pics of these bolts and the rest of the system. If you want, I can make you up a set of 5 modifyed EARLS fittings With the Cummins washers ($1. 00 each)and 1 of the fittings will be turned into a 3/8ths barb so you can come off the OEM SS fuel line on the frame to a 3/8ths rubber fuel line on to your lift pump VIA this new barb fitting. $50 will get you the steel modifyed fittings with 5 cummins washers plus what ever the shipping is. Im surprised no one I know sells these steel fittings. May be Scotty does? http://www.dieseltruckresource.com/pics/showgallery.php/cat/500/ppuser/31605

I have 3 brands of AN fittings on hand now: Aeroquip, Russel, and Summit. I bought the Summit's to save money. Turns out it was a waste of money, because they are of such awful quality that I refuse to use them.



The Russel I bought also for price, but they seem to be of good quality. At least, they "appear" that way. I have not tried them yet.



The Aeroquip's I have are of outstanding quality.

I find the Aeroquip internal screw part is a more gentle ramp into the hose ID and goes in easier than the Russel's. I only use Russel's if I HAVE to. Local parts supplier stock them and is easy to get if I forgot an angle or got the angle wrong.
