here is a better illustration of the new fittings.

you can put an oring or wedge what the stock GM connector had in there to force the tabs on the plastic to stay engaged in the metal outer piece and zip tie it on or similar - it seems the vibration works them off over more more then a single heavy pull or tug

Thanks for posting this. I had a slight concern with my white clips looking abnormal but I didn't know it until someone else said something. I also believe it has to do with the annodize coating they use. I have the black fittings and it looks the same exact way. Since the Corvette regulator won't be seen ill cut rubber hose the length of the regulator body to the an fitting to make sure it doesn't pop off.

It really is a shame that it even had to come to this. A huge company like that should never let customer satisfaction take a backseat like the way they did.

Wow. Wonder if they'll do a recall or exchange program or something. Is there a point of contact for this issue? I'd certainly like to get myself on the list of people who have had problems with the other design.

After looking at this I believe I will be making my own nylon lines. It will look OEM. I have my eye on a Dorman kit right now.

Yes, I would like to know more about this... I just got mine not long ago, and want to swap them out for the new versions.

If I understand this correctly, they have removed any positive retention provision with this new design. It looks as though it's the rubber o-ring that retains the fitting (by friction) to the fuel line. This engineer is less confident with this design, unless I've overlooked/mis-understood something in that link.

Just got mine from some guy on ebay offering "damaged box" kits for $99 + actual shipping cost. Turned out to be about $115

I'm also considering just re-doing everything and getting rid of as many specialty/conversion fittings I've used. Should have done nylon/OE type lines from the start, it will be fairly cheap this way.

Think I found the answer to my doubts of the design. It's not immediately clear in that link, but the nut in the illustration is slotted and radially slips over the swaged portion of the GM line. This does make it a positive retention system. The Russell catalog page (under new products) clearly shows the slot in the nut. I feel better now.

Ditto to the question: Are they going to exchange/recall the old one's? I've got 3 @ $16 each, so that's $48........

I can't find a pic of the black style with the new design... Are they also redesigned ??

I'm no lawyer, but seems like it would be law suit material if they don't at least put out some kind of recall notice on them.

There is a black and a blue catalogged on the Russell site, but it looks like re-designed one's are only avaiable in a -8AN (the catalog/new products section is a bit confusing). Anyone know different?

Why not http://www.jegs.com/i/JEGS+Performan...10551/10002/-1use this instead. Then use the typical An fittings. Cheaper than the SS compression fittings

Might be OK on aluminum line, but don't try and use it on steel. Besides, I saw somewhere they only have a 50 PSI rating...

-8 AN male to 3/8" SAE EFI Female Push on Fitting red/blue (644000)* black (644003)*

* Fits LT1, LT4, and LS1 (pressure side).


8 AN ??? I thought stock hose was 6 AN

And what's with the old pic ?? Can't they update their **** ? It's like only THE MOST IMPORTANT FUEL CONNECTION ! at the block over the headers ! sheesh.

Swagelok makes an excellent product, no doubt about that!

John, have you ever had a failure with a Swagelok tube fitting on a fuel line? I have been told that you shouldn't use compression fittings on fuel lines, however, I know this isn't your typical compression fitting. I have one on my fuel rail, feel pretty good about it, and have not had a problem with it yet. I had a nice discussion with my local distributor (very knowledgeable) and he felt that the application would be fine.

Swagelok insists that you should never use any other brand component with a Swagelok fitting. So if you are going to use a Swagelok fitting, use the whole fitting - don't mix and match the small parts with Parker brand, etc.

Is brass suitable for fuel line use? I used brass on mine but I am thinking about changing it. I heard that the brass will react with the fuel and eventually cause the fuel to gum up.

I just got off the line with Jegs tech. They said the hardline AN adapter (555-110551) fittings are rated to 250psi. Good enough for me to at least try it out

ANOTHER ONE POPPED TODAY!!! WTF?!?!?! It was the fitting at the return line off the vette filter...I didn't realize it this time until the truck puttered to a stop and died...I must've been spewing fuel as I was going down the road cause the tank went bone dry!!! I will be replacing ALL of mine and plan on speaking with Russell/Edelbrock tomorrow!!! I know this IS NOT a user error as I remember testing them for locking upon intial installation...

Wow! I need to go with the Dorman kit and make it OEM style fittings. I'm glad nothing bad happened. Nothing IMO is more important that oil and fuel fittings that don't leak.Especially with our fiberglass cars.

I also know that my fuel system is only pushing about 55~58 PSI and nothing over so it's not too high of fuel pressure popping them off...
