<VV> Engine pre-oiler

OK I want to pick the gold mine of tech filled brains out there. While I was 'Vairless I continued to think Vair thoughts. One was I have pre-oiled a few engines after major repairs or after sitting for long periods. It occurred to me that my Vair or my Manx (Vair engined) would sit for periods of time or at least most of the winters here. I am sure others are of similar thought. It is not that difficult to pop out the dist. and turn oil pump on a Vair but it takes time and then you might move something and have to readjust everything. Now I have heard all my gearhead days that most of the worst wear comes from those few seconds at startup while the bearings are screaming for the oil to get there.

My thought was "on-board oil primers". Yeah, yeah, yeah I hear some of you yelling that there a couple of different kits and ways already out there. But they cost money and quite frankly I enjoy doing it myself. Think of it if you pre-oiled every time you started your engine it might last a million miles. Also a way to cool down Turbos or race engines after runs.

I see two ways to go about it.1. quick connectors so you could move it between vehicles. Handy if you have more than one vehicle that sits. Also a minimal weight penalty for racers. Or 2. permanently mounted. This would most likely mean 12v powered. Although 110v could be used (plug it in and disconnect it).

I know of Accusump I like it. It also provides emergency oil while running if you lose oil pressure. But it requires residual oil pressure. I am told that they can lose pressure over time. Not the perfect solution.

Now I did some research a while ago and went to Shurflo. They make a gazillion different pumps. Talking to one of their techs he suggested a particular pump that was used to provide cooling for differentials in race cars. I bought two (about 70.00 each 10 years ago). They do put out considerable pressure.Of course that is as far as I got.
I have studied the shop manual. I haven't had an engine apart since this idea came. I just got my spare 110 in the garage so I might do an autopsy soon. So my question is where would you plumb this contraption? Considerations: Could you use a remote oil filter adapter or remote oil cooler. That would have other benefits. Also I would plumb in some valves so hot oil wouldn't circulate while driving.

My quick and not so dirty solution would be to drain the oil, you could leave container under engine with drain plug out. Then with pump piped into oil pressure sender pipe you could suck from the drained or fresh oil and pump into the sender pipe. This would require shut off valves and such. Not the best solution either.

 Would that work? I am afraid it might go backward to the oil pickup and waste pressure. Are there one way provisions? My head is hurting. I will turn this over to you guys.Go for it guys!!!!
