The Canton 22-569 adapter is listed as a: "UNIV SINGLE OIL INPUT ADAPTER 22mm-1.5"
I agree that both the Canton and GlowShift adapters seem to function in the same way (port-path wise).
Maybe I'm just being thick, but I don't understand why this wouldn't allow me to pump oil from my electric pump into the pre-filter port of either the Canton (or GlowShift) adapter. The outside of the filter (the small holes around the perimeter) is where the oil enters the filter and then, after passing through the filter media, then (assuming the filter is not clogged) the oil exits through the large center filter opening. Correct? I don't think enough pressure will backflow through the engines mechanical oil pump to make that much of a difference unless the pump gears are extremely worn. I don't know what path the oil takes inside the engine after exiting the filter, but I find the cranking my starter for as little as 4-5 seconds is enough to get enough oil into my hydraulic chain tensioners to allow for a chain-noise-free start and the oil pressure hasn't reached the oil pressure switch yet, as it takes approximately twice as long (9-10 seconds) for the needle oil the dummy pressure gauge to jump up.
Are you saying the pre-oiler should supply oil to the center port of the oil filter? That doesn't make sense to me. In talking to david4451, he told me he would have used the Canton 22-569 adapter. To quote an email I received from David this morning... "That adapter is what I'd have used if I had not made one".
I'll have to go back and review the photos David provided, but as I recall what he did was to have a long treaded, hollow extension pipe made to allow installation of his "engineered" filter adapter, which he also had made. There's only a single hose going from the electric pump to his adapter so I believe the adapter only had one input port and it feeds into a remote filter adapter, then presumably off to the remote mounted oil filter. David reports no problems with his setup after at least a month of use, so I'm expecting the same result.
Are you saying that because David is feeding a remote oil filter it's somehow different than an adapter mounted filter? If so, how?
You're very knowledgeable and I respect your opinion. Like I said, maybe it's just me being thick, but I'm having trouble understanding why my setup will not work, Whether I take oil from my oil drain plug using and electric pump, or let my engine's mechanical oil pump to take oil from my oil pan the oil still goes to the input side of my oil filter, passes through the filter and then into the engine's oil galleys. Right? What am I missing?
Edit:
I reviewed David's photos and he does only have a single port in his adaptor from his pump. I suppose his use of the 2 port remote filter adaptor could feed either side (input or output) of his remotely mounted filter but this doesn't make sense to me that he would do this. I will ask him if there is a reason that he used a remote filter.
