Oh and it's not "Siphoning" back it's leaking back via the check vlave in the pump.
If I remember correctly (been 45yrs ago) when my Dad had a slide in TC it used the same type of manual pump.
With that type of pump, you must make sure you return the handle back to the prime/store position which if I remember correctly the handle was in the up position.
Pulled the handle down would pump water out then you had to return the handle to the up position.. Failure to return handle to up position would result in the same issue the OP has, lost prime. Then you would have to go through repriming the pump..
Can't find any instructions on these pumps to look at and verify correct position for storing so OP might wish to try storing in the opposite position they are currently using to see if it stops losing prime.
Otherwise might be a bad built in check valve and replacing faucet or adding a check valve may fix it.
