Oil Drain Valve - Fumoto
« on: May 14, 2017, 01:21:14 AM »
I have a Fumoto oil drain valve on my GMC 2500 HD diesel truck, as well as a couple of friends on their trucks, for the past 3 years - operating flawlessly. I now want to put such a valve on my 03 350 ISC Cummins. Does anyone know what size oil plug I have on my Cummins so I can order a replacement valve?
Thanks!

Bart, I think most all the ISC's take a F 104 valve 18mm-1.5 , This info comes from Fumoto's app chart for all engines.

Lee - thanks for the info! I was looking at the wrong site, which didn't have the engine chart to which you referred.
Many Thanks!
