Has anyone used an electric prelube pump or have any advice on where to find one and where to hook it up? The car I’m building will sometimes sit for long periods. I would consider using an accumulator but the engine bay is tight. It might be easier to find room for a pump. I’m using a Aviaid Cobra oil pan and less concerned about needing an accumulator while driving. Just want to be able to prelube.

Why not just spend 10 minutes, and Re & Re the distributor and prime the oil pump manually before starting the engine after sitting a "long period", whatever that actually is. If it`s only a couple of months, I wouldn`t bother even doing that, assuming the engine has some running time on it, before being parked.

Is there a trick to doing that correctly? My engine is on the stand and I need to turn the engine slightly to get the distributor to seat properly. In the car, I’ve heard you may need to bump the starter. How can you make sure the distributor goes back to the same location it came out at?

With the cap removed, mark the distributor body to the intake manifold. Maybe a sharpie or paint marker. Then mark where the rotor is pointing, and mark something inline with it. As you remove the distributor, make note of how much the rotor moves, in reference to the distributor body. When reinstalling you will have the rotor positioned such that as it engages with the cam gear once again, it will rotate to where it belongs. Then you can align the distributor body with your mark on the intake. For me everything is close now, I would most likely re-check with a timing light. Personally, when I leave something sit a long time, I’d possibly turn the engine over by hand, then remove the coil wire and turn the engine with the starter motor, then start it, versus removing the distributor.

long storage pull plugs- oil cyls- spin to lube install plugs- tape ex ports or header- seal engine good--------- when start prelube by pull plugs---spin with starter to see oil psi or under valve cover see oil flow --- i would never bother pulling dist---- seal good-prelube with starter --ready to go- no dist. worry---you have oil pump and starter to prelube john

Another option would be to put a T fitting on your oil filter adapter, with a "dry break" fitting on it. Build or buy a accumulator and put ball valves on it to connect to the dry break.
It wouldn't cost to much and it would be a sure fire way to do it, in just a couple of minutes.

Thanks for all the ideas guys

I have one on my Cobra with the Aviaid pan. It works great. Whenever I start the car after storage or even for the day, I flip the switch and the motor is preluded in like 10 seconds. Simple and effective.
Check out these pumps, Infinity Aerospace GP301-12L or maybe Reverso Pumps

338 Raptor that’s some stable tour got there

338 Raptor, do you pull from the drain and run through some kind of screen or filter? Could it pump into the port on top of the oil filter housing which I think is only 3/8”? And could it have a valve that would let you pump the oil out for oil changes?
