A couple of people had asked me about my Accusump installation.
As far as I know, most have used the oil filter adaptor to hook up to the Accusump.
Doing the installation in that manner means that you need to use a half-sized oil filter which is only good for 1,500 miles or so and it also means that you have to use an extra-long oil hose, neither of which I wanted to do.
So, I studied the M96 engine and came up with an alternative solution which I think works even better.
The M96 engine pumps oil through the oil heat exchanger in order to cool it down.
I figured that this point (top of the exchanger) would make a perfect connecting point for the Accusump and is near enough to the rear trunk to use a 24 inch hose.
I punched (can't drill because of the danger of leaving metal flakes in the exchanger) a hole at the top of the exchanger and welded an aluminum pressure fitting
I then connected one end of a steel braided line and secured it to the top of the block with tie wraps
Then I punched a hole into the trunk, just under and to the left of the coolant reservoir and put a rubber grommet to protect the line, passed the other end of the line and installed the fitting.
I then tapped into the wire harness in the trunk to power the electrical oil valve and installed a switch
Finally I installed a dry quick disconnect coupling so that I can unplug the Accusump and use the full trunk space when my wife comes along.
Then it was just mounting the steel clamps to a piece of 1/4 plywood which is also secured to the floorboard.
An here's how it looks in the trunk
This is the 3 qt. size which will give me a continuous supply of oil to the engine for 17 seconds when the pump starts sucking air and the pressure drops below 35 psi.
There's an added advantage that since it's connected with the ignition switch, when the engine is switched off the Accusump retains 3 qts. of oil at pressure.
When I go start it next time I first switch on the ignition allowing the Accusump to pre-oil the engine before it turns over, eliminating a lot of the wear at cold start.
It works very well. I'm very happy with it.
