1. Yes, they do work.
2. They're pricey.
3. I can't afford 'em.
4. Have you thought about and oil accumulator?
5. Take a look at Accusump.
6. It's fairly priced, and works well.
7. How about a DIY Preluber?
My question for you. I could do away with the pressure/check so it doesnt automatically cut off and I could just install a switch so when I get to a desired Oil Pressure before starting the engine I could just cut it off. Another question on the 2.5L where the Oil Pressure Sending unit screwed into the block tell me if thats before or after the flow through the OIL FILTER? Since there would be no point in putting unfiltered oil all over the engine before startup correct? Do you know of any eletric pumps that would be good? Size of hydraulic hose?
I'm going to be installing one of the dual kits on my CJ once I get the engine running again. It would seem to me that it would be very easy to just plumb the pump into the return line, then you have 2 quarts of oil to pump into your pre-oiler.
1.) If you use the drain plug as a pickup for that pump it is hanging awful low and could get broke off on the trail and you'd be with no oil fast, but you could pull off the pan and put in a pickup for the pump up high.
2.) I'd put a check vavle on both hoses to be safe.
See thats exactly what I was thinking. But trying to keep costs down it might work just going through there because on the 4.0 it goes straight through into the filter and then to the engine. But I always wanted to add a remote filter so maybe this could be some extra Protection?
