I'm not real sure how yours is
i need a filler to modify and put on a old willys jeep fuel tank
this one just so happened to be laying in the bed of dodge ram pickup truck (whether it went to the truck, I do nt know)
yours may be sorta like this--upon looking thru "mitchell i" I could not find a diagram of your system
with my super engineering skills, I think the only real reason for a check ball is for "anti slosh" and might also prevent gas from coming out of the gas cap if the vehicle turned over.
I have seen them broken and floating around somewhere in the tank---and no repercussions occurred, still drove fine, with other vehicles
these too might also prevent a "novice siphon-er" from stealing your fuel. But someone could ezily punch this thing on, into your tank. Its sorda a fragile cage around the ball.
What possibly could happen to one like in my pics, is a small hose, stick or foreign object get inserted into it, and broke off when it was snatched out or was small and wedged itself between the ball and the cage
it's also possible that the "seat" or portion of the cage the ball rests in, when fuel pushes it upward after you are finished installing fuel. This part may be worn from the ball bouncing on it over the years, and the ball simply just sticks or lodges into the seat.
If yours is like this, 1st investigate at an auto parts store, can you get just the plastic "check valve assembly" or must you buy the whole filler assembly (napa, autozone, advance auto are some to check out)or is this strictly a stealership item?
The auto salvage yard is yet another option, and I go there often myself
after exploring what you can do or can get and where it's available.I would remove yours and try to determine if you can simply remove missing action figure "darth vader's light saber" from the assembly and all be like new. Or does it need new parts?
As far as the fuel sender, it is most likely unrelated (but you never know)
if you can live with it. Wait until you have fuel pump problems and the tank must come out anyway to replace the pump and the faulty sender
i'm a great example for you (probably not practical for you) I never worry about running out of fuel on either of my two jeeps, my civilian '77 cj 5, as well as my '46 willys army jeep, both have 5 gallon cans on the back, mostly for me. But have helped those stranded too!
Let me know what you find, I hope it's ez!
