Outlet barb came out of fuel pump

[pdx6169]

A routine annual fuel line replacement took a sour turn when the barb pulled out of my dome top fuel pump.

What are my options here? It didn't take much force to pull it out so it's probably for the best that this happened now rather than while driving. I lost a Bus to a fire in the late 90s and would prefer the best fix possible. I'm planning to attend a show in 10 days and now that may be in doubt - I'd rather fix it right than fast.

TIA for suggestions!

Remove both tubes. Scuff the brass tube end with 180 grit paper to give it a tooth that goes into the bore. Apply Loctite green retaining compound and hammer BOTH tubes back in with the Loctite. If you apply it right, the tube won't come out again.

Similarly, I rolled my inlet pipe between two coarse files to dimple it so it would stay put.

I would use a files on the tube with a cross hatch pattern and JB weld it in place. Also do ad this to the pump to so the pin does not fall out or have a chance to fall out. A lil homemade item front of pump and rear.

Thanks all for weighing in. I believe this has been repaired. Just went for a successful test drive.

Per wcfvw69's advice, I scuffed the end of the outlet tube with sandpaper. I used 120 because I didn't have 180 on hand - just a bit of light scuffing was needed as the brass is soft. I rubbed the paper horizontally and vertically along the tube to make a bit of a cross pattern. I then cleaned the outlet tube with brake cleaner, and used brake cleaner on a q-tip to clean the inside of the bore.

I then used a tiny acrylic craft brush to apply a thin layer of sleeve retainer to the tube and inside the bore. I went with Eskonne 638, which appears to be an Amazon imitation of Loctite 638. I then gently tapped it home. The existing knurling on the tube did not go in all the way, but looking at the photo in my original post, the knurling left teeth marks inside the bore which indicate that the tube is about as far in as it was before.

I let the retaining compound cure for a day. I didn't go nuts tugging on the tube to test it but it feels very solid. I put a new fuel line and clamp on, and topped it off with a simple loop of safety wire around the clamp and fuel pump. I don't think it will be going anywhere . I will probably just leave the wire on for shows - I often find shows to be educational and maybe seeing my setup would help someone else.

Went for a drive around the neighborhood, everything stayed in place and I didn't notice any leakage or fuel odors.

i have the same issue with a 34 pict 3 carb im working on . i have that green 638 loctite in my amazon cart .

I like the safety wire.

My own 1970 VW had factory crimp-clamps on the lines at the fuel pump, and about 1975 the one to the carburetor came loose and spilled raw gas over the engine area and I drove like 5 miles like that (didn't notice a performance issue), got home and liquid gas was all over the engine tins by the distributor, was a miracle it didn't go up in flames. I was so scared I just let all that gas evaporate, then added my own clamps and safety wires.

I was extremely lucky.

The German fuel line grips the brass tube tighter and tighter just like Chinese finger cuffs the more one pulls. Best to use a flat tipped screwdriver to push against the hose end to move the hose off the brass tube.
