I've a 2 quart Accusump to plumb in. I've looked at plumbing it into the return oil cooler line but that seems to involve a lot of fittings and hassle. As an alternative, plumbing it into the oil gallery at the middle of the block looks increasingly attractive. Any recommendations from those who've done it? Suggestions on fittings to use? Thanks. James

James, The oil gallery is the preferred location as the oil is pushed directly into the main oil gallery when the Accusump discharges. It's been a number of years, but as I recall I just unbolted the gallery cover, drilled and tapped it for an AN 10 fitting and plumbed it directly to the Accusump valve using SS hose. Pretty simple. You can source the appropriate AN fittings and hose from just about any speed shop. I think the Accusump units are excellent and relatively inexpensive insurance for the 907/910/912. Scott

I have been considering the installation of an Accusump or MasterLube as described in the March 2002 issue of the JHPS Magazine. I like the idea of pre-oiling at start-up. You see as my car is not started every day, many times (if it sits for a period of days or weeks) it takes a considerable amount of cranking to get her started. I also experience rather low oil pressure when at an idle after engine warm-up. I was thinking that while driving the car, I could turn on the valve at some of the longer idle stops to get the additional boost in oil pressure. My concern is that by using these sorts of oilers during normal operation of the engine, am I going to introduce too much oil into the engine? Can the valve be left on full time when driving the car? I was thinking about installing a 2 quart system. Anyone have any specific recommendations or thoughts on the matter. While were talking about oil pressure. What is considered the minimum acceptable oil pressure of a fully heated engine while at idle? I just want to know if I should be overly concerned. I was also wondering if anyone has any thoughts on the idea of automatic valve/relay system that would open the valve automatically if the oil pressure would drop below a preset limit? Thanks for any advice, Jay Last edited on 03-07-2008 05:52 pm by Jay |

I use the electric valve on my 2qt Accusump. For start-up I hit the switch, watch pressure come up, hit the starter and dis-engage when the oil pump takes over. Rarely do I ever use the Accusump on the street once the car is started as the engine does flood with excesive oil at idle. Competition is a different animal. When I hit the track and bring the engine up to speed (high oil pressure) I leave the switch on. Of course the trick is to turn it back off before shutting the engine down.

James, If you are just street driving, Scott has the best solution. Judson has also given the correct proceedures and characteristics of operation when running on the track. Do NOT leave the Accusump connected during street driving ! YELODOG has a 3 qt Accusump connected via an adapter at the location of the stock Oil Filter. But, I have a remote oil filter, and the plumbing gets more complicated. If you are interested in a competition configuration, send me an email and I can forward drawings of my setup. See also the extensive discussion of Accusump in this forum "Accusump" last post May 19, 2007. Lots of the issues are covered there. Pete Bahr YELODOG

Accusump or MasterLube Still trying to decide which to go with. The Accusump with it's piston between the air and the oil, or the MasterLube with air over oil and no piston. As there are no moving parts in the MasterLube version, I was about to go with it. Then I began to wonder about there being an issue with the air charge being lost on the MasterLube version if the oil is allowed to entirely excape. Does anyone have a list of some pros and cons of one system over the other? Please help me decide. Thanks, Jay

Jay, I would think that the MasterLube design would preclude loss of air charge, like a bladder or something. Why don't you check with the manufacturer? How long does the bladder last? Is it as good as the ones in the Stromberg carbs? ;-) That being said, I've had Accusump in YELODOG for 10 years with no problems...... Pete
