Oil pressure gauge

Hey everyone,

I recently bought a durite capillary oil pressure gauge to use as a temp install to assess the pressure due to low warning light coming on and staying on whilst engine running (otherwise running normally).

However, the adapter doesn’t fit. Any ideas where I can get one that will?

Thank you,
Dan

Some here although I can’t remember which one I got
Adapter screws into oil switch hole and then switch goes in adapter and tube to gauge

Thank you I’ll take a look.

So, I haven’t had any luck with the gauge adapters as of yet. I also purchased a new sender but that does fit either.

Has anyone got any idea what thread I need to be buying? I’m not really sure how to tell.

Picture shows current sender at the top, gauge adapter in the middle and the new sender bottom.

Thanks,
Dan
