i dont but im all for stuffin shit in her ass to make her go away
so i am guessing i have the wrong size oil pressure sending unit.
NO REGRET$ ... Arguing on the internet is like competing in the Special Olympics / no matter how good you do you're still retarded!!!!!
when you say reducer you just mean like a step down right. one that will adapt the oil pressure sending unit to fit the hole in the block?
better to mount the pressure switch in the upright position like you have.
