Long story short, port motor oil has a press to fit sending wire on the oil psi sender. Stbd motor sending wire has an eyelet with a crush washer and a tiny nut. Needless to say the press to fit is 1000% times easier to get on and off.

Will this work? Thats all my Googlefu is coming up with after scorching my arm and torso trying to tighten that stupid nut.

Shorter story: Low oil pressure traced to either a weak sender or bad wire. Either way, when I hooked up a mechanical gauge, I picked up 10psi across the board, so Ill take the win. (37-43psi from 1,000-3,000 RPM).

Wow dude it says FORD right in the ad..... do not substitute auto parts for the correct marine parts SMH

Wow DUDE, like there's something specific about a wiring pigtail in a marine app versus automotive. SMH/WTF
Hint: There isn't!

Anyhow Learman, what you linked should work given the ID is matched to your stud.
I suppose every one of that style is consistent/standardized.
Further here is part numbers and links to various "brands".
You I'd guess have a Napa local if that's the way you want to go.
Better value for the 50 cent part it is.

But oh no they say coolant not oil. OMG

Thanks yall. Sonic is giving me a hard time because...well.....he is like that haha.

Im just happy to have dodged a financial bullet.

Yeah it was a joke! I figured someone would overreact.....nothing more than one friend busting on another.

I sure missed the sarcasm.

You never know, there are some on here that are "Marine" only part goons at times.

Winter time you’ll get a lot more reactions.

Paint it white or black, double the price and its magically a marine part.

and then, we have metallic blue paint

Wait....wut? They come in blue? But seriously....that nut/washer combo is just asking to be dropped into Narnia.
