The leaking AN fitting saga (continues)...

[dville_gt]

Well, rather then fight the -12 bulkhead and the -12 90* AN fitting I figured I'd just send them back to Summit and start fresh. No way would the replacements also leak, right? WRONG. Go the new bulkhead in and the -12 90*, and guess what, still leaking from the same place.

It leaks right between the collar that goes around the inverted flare part.



Not a big leak by any means, but just enough to leave a wet spot on your finger every time you run your finger across the fitting. I doubt it would even drip 2 drops a day, but I figure when it comes to FUEL I want something, umm, that seals.

Got in touch with a Summit rep and they are sending yet ANOTHER bulkhead and 90* fitting, and the QA department is going to "look" at these.

I'd think I am just a moron, but the other -12 fitting, the 2 -10 fittings, the 12 -8 fittings, and all of the o-ring fittings have sealed up great, and I assembled them all the same way. This is driving me nuts. I had them push the "pick-up" back until Wednesday of next week (hopefully buying me enough time to get the new fittings in before I have to return the old one) so that I can continue to play with the car. I absolutely hate having to mess with draining the fuel cell and getting doused in fuel over and over again. Can we have a group prayer that the replacement replacements will seal?

Any input here?

I had the exact same issue with summits fittings, I ordered aeroquip and my issues were solved.

This time around is the internal Oring, you can take it apart and replace it if so desired. (This was likely the problem before)

(the hole in the side of the hex contains the pin, if you drive it through, the nut should come off or slide up the fitting - exposing the Oring)

This is the exact same problem I had before, except to make things more fun the plastic sealing ring that is used on the bulkhead came deformed and Summit does not sell them individually, have to buy a bulkhead. Thankfully they are just sending me a whole new bulkhead free of charge, but seems rather wasteful when all I need is a 2 cent plastic sealing ring?

Any idea what size the o-ring would be, I have -6/-8/-10 viton o-rings here at the house.

Not sure what size it would be, never replaced them myself - but I'm pretty sure you can. Summit sells those plastic rings, but under a different brand.

I have the exact same issue with a -16 45deg Summit fitting on a water line. its a small leak but enough to piss me off. I just called summit and they are sending me a new one. Hope it fixes it

Must be an internal issue. I was VERY tempted to just ask them if I could upgrade to an Earls/Aeroquip/etc. fitting vs. continuing to fight this. I have a feeling it's not good to continue to change hose ends as the rubber gets torn up a little as you thread it into it I think.

Well at least they sent you the right sized fitting. When I ordered the fittings for my tranny lines (I think they were 4 AN) they sent me 8 AN ones (in a bag labeled 4 AN). I called and they went through all the stock in Vegas and them checked in Ohio the next day, and all of them were wrong. They ended up sending me a Earls fitting for free.

[dville_gt]

Well, no surprise, the third fitting leaks as well.

To Summit's credit they offered to overnight me a -12 90* Aeroquip fitting at no charge.

That sucks. I put the new fitting on yesterday and so far no leaks. It is still a summit fitting but a different color, but I don't think that has anything to do with the fitting.

[dville_gt]

Ya, it probably doesn't hurt that I've spent a butt-load of cash with them over the past 2 months (like 8-10 orders), or that they've replaced this fitting 3 times with the same exact problem. I told my girl last night, if they don't overnight me a different brand fitting I will never buy from Summit again. She work for an online retailer and was like, "don't go demanding that, and in all reality don't expect that they will." So now it's a bonus, I get what I wanted and I get to tell her I was right! WINNING.

I wonder if the problem isnt with the bung on the fuel cell. If there is not enough of a cone at the top above the threaded part, wont it keep the fitting from tightening where its currently leaking?

Have you tried switching the two hoses on the fuell cell around and see if you still get a leak? I know it may be hard depending on how short the hoses are but if the one that currently does not leak, leaks, then you know where the problem is. I find it real hard to believe that 3 fittings back to back leak like that without there being another problem somewhere.

I've replaced the bulkhead each time as well (@$15 per bulkhead and $17 per fitting + shipping I'd say Summit has over $100 in this deal before sending me the Aeroquip which was $30+shipping)! I might give that a try tonight and see, only problem is I run a 90* out of the fuel cell and a straight fitting on the other end so it'll be hard to get it to connect to the pump if it is on backwards.

Oh I didnt realize the bulkheads were also summit. I thought they were welded to the cell. Yeah thats a big problem then. I still think the problem is with the cone shape on the bulkhead, if that part seals up again the AN fitting then it shouldnt be able to leak. I still cant believe it leaks after all the times you have replaced it though.

I would ask Summit to give up and send you Aeroquip replacements and look into it on their own without you being the guinee pig.

Well, they are sending me an Aeroquip 90 as we speak (should be here tomorrow). If that does not work then I will ask them for an Aeroquip -12 bulkhead as well.
