Questions: Silly me! I bought this gauge w/o measuring the hole in the dash. It is 2 1/2' diameter. I had rather not cut another hole, unless I have to. Do you have any similar oil pressure gauges for my '61 C-3B? An ammeter, as well?

If you have an 2.5" hose that is unoriginal in your vehicle. Please send firstname.lastname@example.org a pic of your dash and I can take a look what all you have going on. Thanks!

Questions: I have a 1962 Willys pickup. Will the amp and oil gauges work on my truck? And do you sell a sub panel for mounting them?
Question By: Bob on Nov 18 2013 12:00 AM
You would have to drill holes in your dash if you have a Willys Truck to make these work but yes they should function properly.

Questions: I have a 63 CJ5, my oil gauge quite working. I would like to keep my direct oil line pressure gauge, do you carry the replacement for it? also what pressure should my F-134 engine have?
Question By: Anonymous on Sep 15 2013 12:00 AM
We can help you convert over to a separate 2 round gauge if you like. Minimum safe oil pressure is 6 psi at idle and 20 psi at 2000 rpm.

Questions: I was wondering what it would take to hook this into my 1961 cj5's oil system, and I was also wondering what could be causing my oil light not to work?
Question By: Anonymous on Aug 14 2012 12:00 AM
They never used this style on a CJ-5. You should have a oil sender to a dummy light in your cluster. Please call us toll free. We can help you.

Questions: i have a 1954 cj3b with a hurricane engine and I can not find a oil filter anywhere on the engine. Is this suposed to have a filter? And if yes is it a canister type filter? And where would it be installed?
Question By: mike on Jan 3 2012 12:00 AM
They originally mounted in the front passenger side of the block. Alot of vehicles dont have them. They are a canister style filter. We do carry the complete kits.

Questions: Any reason this wouldn't work for a replacement gauge in a 71 cj5, it looks like a match for the stock gauge.
Question By: Doug on Dec 8 2011 12:00 AM
In 1971 the oil light was built into the speedometer cluster but for a separate gauge it would work fine.
