I'm buying 2 pair of these to get something with new aluminum threads.

Then go to an AN6 to barbed fitting. Should make it quite a bit tidier under the tank. With the pump in the trunk I'll drain the tank with the firewall to engine fuel filter hose.

For those that need hoses and fittings. I use A1 Coupling on Tualatin Sherwood Rd.It's a commercial place, but great service even for the dinky do things I buy. Last time I was looking to replenish my supply of Oetiker clamps and they took back into the warehouse to take my pick of styles.

I am thinking about doing the same thing in the Spring when I pull my tank in the '74. I will watch your progress - thanks!

Another lesson from this experience. After you drain the tank of POR15 sealer and your letting it drip out the big sender and fill holes (upside down). Clean the threaded fittings and put the nuts back on loosely, or the sealer will set up on them. Tried putting on the CB fittings last night after they arrived. No go, too much sealer on them. They'll need to be tidied up with the steel nut, again.

Heading to the hose store this am looking for barbed AN/JIC fittings.

This is the exact issue I have - but I used Red Kote. I now have a mess and I don't know what to use as a solvent to help clean up the mess.

I will use the modified nuts as a thread chaser.

Good luck Cary.

I'll update from the shop in a coupe hours.

Had I little trouble at hose shop. They don't really deal in the small stuff. But we finally found what I was looking for.



With my bunged up threads they were tough to get started and not go on cross
threaded. But you can see them sitting here with 2 gallons of gas checking for leaks.
Dry as a bone. But I am going to mark the bottom of the tank .... never remove bad threads

I tested one of them on one of my other tanks. They went on smooth as silk. Nice product.
Note : They seal with an O-ring.

I'd say for cleaning the threads if the tank sealer is your only issue. Clean threads with the nut with the cuts in it. Oil as you go thru the cuts. I turn a 1/4, back up a 1/2. Rinse and repeat until you get to the bottom. I took it off once and cleaned the threads with a wire brush. Then use a new unused nut to tidy up the starter threads.

Looks like a job well done - thanks for documenting this repair so well - cheers!

Final couple shots ............
Tank with my notes on it.



New look under the tank ..........
Zip tie is to take a slight kink out of the pressurized line



New fuel pump layout in the trunk



So tank is sitting there with a couple gallons in it checking for static leaks.
If it passes. I'll pressurize it this am.

The fittings? Is that an AN-6 to AN-4 reducer and then a AN-4 reducer? Where did you get those?

[cary]

AN-6.
Ordered from CB Performance. Part was cheap. $7.

No reducer. That is AN-6 to 5/16 barb.

Did the nut show up yet?
