Accusump Discussion...
Ok, so I am doing a road race car. It definately needs one, 3 quart model, and I am going to go with the 40PSI automatic valve.
My question is.....for the time being, can I use the Oil Temp Sensor cover (stock one) and install just a "feed" line into it? In other words, not plumb it through a cooler block (like the ECS or similar piece)? I know, I am getting one of those too, but right now budget is the issue.
What do you think? I was going to install a check valve in the system so it didn't backflush through the oil pump when I put a cooler on. Is that a common problem with LS-based pumps to worry about?
Thanks in advance, looking for brainpower of the oiling guru's who have been down this road

Do not use an oil temp sensor or oil pressure sensron. use a MANUAL switch.
Also I think you need to re look at your plumbing.
Two reasons: 1 By the time the oil is up to temp and opens the switch, it will dump oil from the sump, which will be much colder into the block. too much of a temp difference
2. the sump oil can be used to pre- lub your block - SBC have piston slap, pre lube reduces piston slap.
When I turn mine on what I do is:
1. turn key to accessory
2. let gages swing and come back to zero
3. flip manual accu-sump switch
4. watch oil pressure gages go UP - as this pre lubs the block
5. 10-15 sec latter start engine.
also with an accu-sump also time to install an oil cooler.
Hot oil goes to the oil cooler up in front of the radiator or EOC
then to sump
then back to block.
Do it right or dont do it at all. Many guys who have raced T1 have done so with out a sump, just add an extra quart and oil cooler.
trans cooler left, oil cooler right you can see the stainless steel lines with red high temp insulation over
an other pic of the lines
PPL put sumps in several places
Mine is under the left fender

You can plumb it straight to the block still. There is an oil galley on the left front of the block. Use Earl's fitting #9919FFJERL. If you go to davidfarmerstuff.com he has a pic of the location. Go to the Road racing section and you will find about 7 threads on this, including location, switches, valves etc.. I have my stuff to do mine, just can't find the time. Spent tonite removing ebcm due to 1214 code. Good Luck.

Thanks for the pics and links, now I see where to plumb it in.
Honestly, I am confused by the comment for a manual switch. The one pictured is an electronic switch, I am guessing its just "on" the entire time? The pressure sensor one works similarly, except that it charges when the oil pressure is above 40 and discharges back into the motor when it is below. Not sure how that would/could be bad. It would also prelube the block and it would be shut off stored full of oil pressure and then discharge prior to cranking the motor. The oil sensor I was in reference to was the stock one in the side cover by the oil filter but I know which ones you are talking about (aftermarket ones).
I will definatley look into the fitting that connects at the front of the block! Apparently GM nuts don't have to worry about washing the oil pump out the wrong way so I can run the cooler and the accusump separately.
Thanks,
Cassidy

manual switch. I have a switch I flip ON in the cockpit. I gues this is wired to the electonic switch.
Why the manual switch? well when I am about to shut the engine off, I rev it slightly to get the oil pressure UP to 45 psi, this helps fill the sump tank, then I switch OFF the sump, let the car idle for a moment then turn the key off.
Switches are where the ash try were.
Accusump left switch - trans cooler right switch

Definitely install the shut off switch in the car. There will be times when you want to turn the key on and not discharge the sump. Some recommend wiring into the fuel pump relay. I don't think you will get much of a prelube that way. Pump only runs for a second or so when you turn the key on.
