Accusump assistance please!

I originally, accidentally posted this in the FE forum but have re-posted it here:

After I got my Lister running I hooked up a 3-quart Accumsump. It has the solenoid-operated valve (as opposed to the manual one). Initially I plumbed the line from the Accusump to the engine into a 1/2" NPT hole in the block, just above the oil filter (it is a Rodeck aluminum block). The hole had been filled with a pipe plug, which I took out and installed a 1/2" NPT to -10 AN fitting in.

As the Accusump instructions say to do, I pressurized the Accusump to about 50 psi on the unit's gauge, then bled it down to 7 psi. I then started the engine, let it run a bit, shut it down and checked the oil on the dipstick. It was way down, indicating the Accumsump had filled itself. I topped off the oil and took the car for a drive but noticed no difference in the way the oil pressure gauge in the car fluctuates in hard cornering. Also, when I turned on the ignition and activated the solenoid manually by the switch in the cockpit, there was no activity on the oil pressure gauge, i.e., no indication that the Accusump was pre-oiling the engine. I double-checked all the lines and fittings to make sure there were no leaks.

I suspected that maybe it was not a good idea to use the threaded hole in the block, so I re-plumbed the line into a "sandwich" adaptor I bought from the Accusump people. It has two 1/2" NPT holes in it and goes between the oil filter and block. I plugged one of the holes, installed my 1/2" NPT to -10 AN fitting in the other, and hooked everything back up. Again I ran the engine and again the Accusump does not seem to be doing anything. It does not create any oil pressure when energized before start-up.

I have not checked the switch and solenoid to make sure they are working, but I did check both of them when I hooked everything up the first time, and they were both operating. I know the Accusump was working in some fashion initially, as it sucked about three quarts out of the oil pan when first installed. Any thoughts on what to do at this point?

Thanks,
