Electric Oil Pump Kit:

A fantastic little electric scavenge pump that can be optionally used in parallel with the normal mechanical one - it clears any residual oil from mini sump.

During testing, we found that if we left the pump on for a few minutes after shut down it cleared almost all the oil from the engine and put it back in the tank.

Furthermore, we found that turning the engine over by hand, while the pump was on, bottoms the piston which pushes the oil out of the lower cylinders and down the front and rear drains allowing the pump to whisk that oil away.

The net result being less mess on the floor and seemly far less hydraulic lock oil to contend with; though it must be stressed that this pump does not elliminate HL.

To fit: simply attach an oil line from the sump to the pump, then from the pump to the oil tank - no mods required at all. That's it!

Item 1 - Hoses and Connections:

The suction hose from the main oil tank to the pressure pump should be 3/8" ( Pervious 5/8" is way too large now). This was once used when the engine pulled oil from a low mounted tank that oil drained back into, it was effectively a wet sump. The 5/8" was used before we ran the fully scavenged system.

Basically you can use a combination of 3/8 or 5/16 hoses (same as link hoses on rocker boxes). So long as the hoses are of average length either will work fine.

In the last few batch runs of engine production we have replaced some of the threaded fittings for the simpler and less expensive ally nipples. We have used these in low pressure connections only. I recommend that these nipple connections be made with "fuel injection auto type hose clamps" they are very strong as they are not the typically worm style clamp and have a steel band with a small bolt that tightens the clamp. These nipple fittings and clamps can also be used to terminate all the return lines to the main tank except the main oil pressure pump supply which should be a threaded coupling.

The JIC threads are all the same as standard "AN" aviation fittings, threads and seats. In due course I'll change that terminology too.
