mechanical gauge to check oil pressure

[911SCcdn]

Can someone steer me in the right direction?

I need to purchase a mechanical gage to check my oil pressure. I think I have a bad sender and it was recommended to check the pressure with a gage.

I have been to a few autoparts store but no one seems to have one. I would like to order one online if possible, if someone has suggestions.

Any help would be appreciated.

Thanks

any univeral gauge will do. get one with a flex hose and adapt the hose to a fitting that screws in in place of the temp sensor, which is to the right of the crank pulley, facing to the rear. early cars have access to the top of the bellhousing area oil fitting.
