Fuel tank question w/pic

[Old'sCool]

I need to credit Bonefish and his gorgeous 23' for this picture. It's the best example I can find.

How would one inspect the pick-up tube in this picture?

Is the tube small enough to slide through the male npt boss welded to the tank?

usually the tubes are welded to the tank with the elbo threaded in, sometimes the tubes are threaded in, depends on who made the tank, sometimes there is a screen at the bottom which is a P.I.T.A, if it's clogged you might have to put another tube in with a flange similiar to the fuel sender.

Looks like there are 2 pick up tubes for dual engines. Are they both clogged, maybe switch the fuel hose around?

In the picture shown, the far right fitting is the one in question. The female threaded fitting is welded to the tank and (I believe) the anti-siphon valve screwed in. The other two are fill and vent. I want to know if the pick-up tube is removable through this threaded fitting??

Sometimes yes, sometimes no, depends on who made the tank.
