The Stovebolt Site Forums The Shop Area Engine Shop Oil pressure gauge line

Need to connect my existing oil pressure gauge line to the 235. On the old 207 it ran to the block, and uses what looks to be a small 5/16-24 compression fitting/nut. The 235 had a 1/8 pipe T that feeds the oil filter and I'm assuming the T was where the oil pressure gauge connected??

I found a 1/8 pipe to 5/16-24 female adaptor, but it's not a compression adaptor. Is there a conversion adaptor, or a new line kit out there somewhere? I'm going to be using the stock oil filter canister.

Thanks.

P.S. Didn't know if this should go in engine or interior

Found this in another post. I'll have to see if this would work on the gauge end.

Most aftermarket oil line kits include the adapter with the inverted flare compression fitting, Normally the line is 1/8 inch, I like the kit with copper line vs. the plastic. I think the Napa kit will give you everything you need.

I found this kit which says for '37-later. So I think the problem is, once again, my '36 is different. (just like everything else!)

I think I'll have to see what size it is on the gauge end. Hopefully I can convert to the '37-up kit.

I bought my kit from Chevs of the 40's. It came with a few fittings. LINK

I think I see what's going on here. It looks like the threads on a 1/8 compression fitting are 5/16-24. That's what I have on the end of my oil pressure gauge line. It's a male compression fitting/nut. So it seems I need an adaptor with 1/8 NPT male on one end, and a 1/8 female compression on the other, which would be 5/16-24. I'll see if that exists. Or find a new compression fitting with male 1/8 NPT on one end. If not, I'll buy a new kit.

I think this will solve the problem. Just cut off the existing fitting and use this. Thanks for listening to me think out loud.

My '57 is a compression/threaded fitting at the gauge. Looks like you will have to use a coupler to lengthen your line if that is the issue.

I think the existing line will be long enough. Where it attached to the 207 was further forward than the 235, so I should be OK cutting it and putting a new fitting on the end. What what you said is always an option as well. Definitely don't want to mess with the connection at the gauge.
