i see that some of the buick 3800 motors use a m10 x 1.25 pitch oil sending unit thread..

this should help you if you cannot find the proper adapter..  as the HF tool only comes with the m10 x 1.0 thread adapter..

clogged or blocked pick up screen openings can effect oil pressure also.

oh... and if you are working on the oil system on a crank driven oil pump that cannot easily be primed... disable the ignition system and with the oil filter off.. crank the engine till you get oil flow out the oil filter adapter.. then  you can screw the filter on and crank engine until the oil pressure light goes out.. this avoids extended dry starts thats very hard on the engine bearings..  reconnect the ignition system and start the engine.. watch the oil pressure light.. it it does not go out within 8 seconds. shut off and wait a few minutes to start again..  you don't want to get the bearings really hot..

motor on..
