Protection valves

[timvasqz]

I just installed a KN31000 which I think protected pressure in the system if there was an air leak at the bulk oil. Typical that everone only seems to have a airleak at the airleak protection valve. This is a common fail part and I think the problem is location not product it is too close to the manifold heat.

I dont think anyone will have the correct answer because they have been replaced with whatever over the years the BB parts list may have an answer in the filessection BB list the number 15759C which I guess is OEM N15759DC parts list also says 65psi and 3100 opens? at 65

Kn31003 crosses to OEM N15759DK

KN31000crosses to OEM N15759DC
