Any of you racers have an Accusump or like setup when running methanol? Any issues with moisture in the canister or other issues to look for. Is the juice worth the squeeze

My car came with an Accusump because the previous owner was using the incorrect pump pick-up and the oil pressure was down to zero in the shutdown without it. Replacing with a better pickup resolved my problem and I sold the Accusump. If I need to pre-oil prior to initial start (like after oil change) I just crank it. I think if you don’t need one for a specific problem it’s best avoided imho.

I, like many, use methanol and ALL my oil samples came back with zero water in the oil. My valve cover interiors are moisture free when I check the valves also. I do not have a vac pump, only evac that actually works.

Lil Brother has accusump on his turbo alky VW. Has not had any issues

I run an accusump and have for years with methonal with no issues.

Don't see the need for one but if you run one it would have the same exposure as all of the rest of your oil system. It needs to be emptied when oil is changed so I don't see how it does anything for start ups afterwards. If anything if you didn't shut it off it would prevent the engine from getting initial oil.

I run one with Methanol and don't have any issues. Which you won't if your tune up is good.

This past weekend I did however have the top of the electric valve just break off and dump the contents in my pit as soon as I parked my car. Scared the heck out of me when I saw it. Putting a cast brass valve back on it to replace the cast aluminum Moroso valve.
