Oil Pressure Gauges

bayhollow · Nov 9, 2017

The oil pressure gauge on my MF 135 is leaking into the front and I have ordered two different new gauges and have yet to find the right one. Mine has the two outlets on it because it has the oil pressure switch on it. Can anyone send me the right part number? I need the oil pressure switch because the tractor has been converted to a one wire alternator unless someone can tell me how to set up the fuel gauge without the switch.

Both early 504 687 M93 and late 528 415 M91 gauges have one 1/8 inch male pipe fitting, and both use a 1/8 inch pipe tee on the back to install the fuel gauge pressure switch. That fitting does not come with the new gauge on the US tractor parts list I looked at. Remove the tee and re use it on the new gauge, unless it's damaged. Sometimes they can crack..

You should be able to put a T in the line. The low pressure switch is napa# 701-1577. Hope this helps.

Thanks for the answers. Guess I should have looked at it closer. I had to put in an extension to be able to get the nuts on the back of the gauge and tighten the "T". Knew I could get the answer I needed from here!
