I just dropped my tank because the gauge quit working to find a failed float (no big deal as 521Restorations is sending a new one). But I was wondering what others have done to re-attach the fuel pickup screen to the tube. Mine fell off and doesn't seem to fit snug enough to trust that it'll stay.

Just wondering if anyone has direct experience with a particular glue that works and won't lead to another problem down the road.

I had a loose filter on my Dart. It actually got sucked further onto the pickup, and plugged the flow. Car died like it ran out of gas. I ended up putting a piece of hose on, and then the filter, so it wouldn't happen again. I wasn't worried about it coming off.

I think I once used a small hose clamp, but that was a LONG time ago...
On another car, I used a late-model big flat filter, attached to a short length of hose, which attached to the pick-up tube.

If you're referring to those nylon type mesh filters, I've seen them in 2 different sizes for the metal fuel tube.

iagree
I bought a bunch of them from the local Chrysler Plymouth parts department years ago, 5/16 and 3/8 pickups, still have some of them left:with the new rubber gaskets that go between the pickups and the tank up:

I ended up using this stuff to glue it back on the pickup

Just find the correct size filter.
I myself wouldn't trust any "glue" to hold that filter on.
If it falls off, any larger particles in your tank will get sucked up the system into pump.
Even with a good/clean tank, never know what's in some gas pump tanks.
But, I guess it's easy enough to check it's condition later on by removing the pickup ass'y..

The glue you attached a link to clearly states it is only gasoline resistant. That mean it will likely never last fully submerged.

I hope it's as good as the people on youtube and other places on the net claim, because it's been used to glue cracks and holes up in plastic fuel tanks with " reported " great success.

I guess it doesn't matter if the glue holds or not, I got my replacement gasket & float from 521 Restorations delivered yesterday and he thru in a different designed filter sock that fits the tube nice and tight.

That's cool! Are you going to check the sending unit calibration before final install? Make sure you have a good ground to the sending unit as well. I used a short length of copper wire and 2 hose clamps to allow continuity between the metal fuel lines and a chassis ground somewhat similar in effect to the factory ground strap which I don't have.

I had the tank out and flipped it upside down to check for how the float arm adjustment was. I had to bend the arm a bit to get mine right at full and empty. My gauge still shows full and slowly drops, but after I get down below 1/2 tank, it drops significantly faster. Not sure if its more than just the way the sender is wired versus when the tank was upside down the float was higher up than the fuel capacity of the tank lifts it.

The original sender was wired up using resistance wire on what looks like a piece of stiff cardboard and the arm has a sweep that rides on that resistance wire to send the reading to the meter. In the original sender that wire was wound in a non-linear fashion to account for the effect you see of the needle behaving non-linearly. Aftermarket senders tend to skip right over that so they can use one setup for any number of senders, they wired that board linearly and you see nonlinear behavior on the meter. After all the only thing that matters is the full and empty resistance reading, right?

I have a similar trick with grounding them. But on this particular sending unit it's in a 74 Ramcharger with a 36 Gallon tank, so it uses a stud that a dedicated grounding wire attaches to. I checked the OHM's on it, and documented best I could what ohm's the rang would read from F to E across 6 positions so if I ever decide to put a meter match in it, I should be able to get it close.

I ran the truck until it would stumble going around corners and still have 4 gallon's of fuel in it and luckily the float bottoms out at about that point.

Regarding the issue with fuel slosh at lower fuel levels, Iam using 2 methods to eliminate air intrusion into the fuel system. I added a Holley Hydramat to the pickup. It's pretty amazing how that works. I also run a surge tank up in the engine compartment. The EFI fuel pump is inside the surge tank sucking fuel from the bottom of that tank. The two methods eliminate fuel cavitation by themselves even when down to the last gallon. The combination of both is actually overkill.
