Misc. What do i need for oil sender

[stvincnt]

I bought this sender for my 79 CJ5 AMC 258 i6 / 4.2l . It doesn't fit in the block. There was a mechanical hose hookup there and I want to use the electric setup. What adapter do i need to make it work.im.seeing elbow fittings the incorporate bot mechanical and electrical. Im going crazy with this. The diameter of the male end is so close . The previous mechanical tube fitting fits (its a bit tapered ans starts in easily) but this new sender is supposed to be a fit but doesn't want to start in. It says its an npt

Those are pipe threads so you would need NPT fittings. IIRC, it's 3/8" in the block and 1/4" for the sender Just take the mechanical fitting and the new electric sender with you when you hit your local hardware store to fit it up. A an adapter bushing should do it. Don't forget to use Teflon tape on the threads when you install it.

I appreciate the reply. is it correct that the engine block only receives inverted flair 3/8 fittings ?

The block is NPT. The inverted fair bushing was for the mechanical gauge.

I have decided I want to use a mechanical oil pressure set up, but i'm having a hard time finding an adapter for the 3/8-24 inverted flare the on my engine block to the oil tube. Im going nuts. The bosch gauge kit I bought doesn't have the correct fittings my AMC 258 i6 / 4.2l is an early it's block
