Re: Timing cover and Hpop gasket questions
If the reservoir has 1/8 NPT threads for the oil pressure switch and inspection plug, it is the older one. If the switch and plug have straight threads and o-ring seals, it is the newer style. If it is the older style it will use the 2-chamber gasket, but the HPOP
pump body needs to be the older style as well. If a later SD HPOP
is used, that is why you get the draindown issue (earlier HPOPs had a built-in check valve to prevent the draindown. Later reservoirs and front covers were changed to have a standpipe built in. The HPOP
gasket was changed to the 3-chamber and the check valve was removed from the HPOP
at the same time). Cheers!
