One crush washer seeps a little in the fuel line crossover banjo. I’ve replace all 5 to proper torque but still a little seepage in the second down washer. Is there a better replacement washer the same size?

There are two crush washer thickness sizes. Make sure you have the thicker one. Look in the illustrated parts manual. I just had this same issue and it was because of the wrong thickness crush washer in this location.
p.s.
Tighten them tight.

One time I got a banjo bolt that was for some reason just a little too long and because of that it would not quite seat properly.

Thanks,
I only see one sealing ring 10x14 part 230150 in the illustration for the 912ULS? Is there a thicker one I’m not seeing?

use this one, 950-143 and it shouldn't leak.
950143 | Brass Gasket Ring 8,2/13/1,4 |
p.s.
If it still has an ooze you could apply a thin film of Hylomar Blue sealer on the "O" rings. It does work without any negative affects. Just don't glob it on. Just a thin film on both sides of each crush washer. Guaranteed not to leak. Hylomar Blue is used for fuel, but it is not de-solvable by the fuel so you don't want any just floating around in the system. Use it properly and it isn't an issue.
Anything can be used wrong. Even a screwdriver can cause damage.

950-143 is the gasket I ordered and still weeps a bit. I’ll try the Hylomar Blue sealant as you suggested and hope for the best. Thanks again
