Half a can of brake cleaner into pump before you start, Start the engine and spray rest of through engine. Another suggestion is to pull lines of vacumm pump and let "air out" after a night of racing.

Every couple weeks, I'll pull the vac pump inlet hose off the valve cover during warmup and, with the engine running, shoot brake cleaner into it for about a 5 count.

At idle, I can definitely feel a big difference on the gauge or when tapping the hose fitting to my palm. As long as I do it often enough, it doesn't make a difference on the gauge downtrack.

Just a note of caution about using Brake Cleaner spray. Yes, it is as good as anything for removing oil & grease. But please pay attention to the label.(Yeah, I realize most of us know this, but not everyone does):
Chlorinated brake cleaner is Non-Flammable, while Non-Chlorinated versions are EXTREMELY Flammable.
Both types work well, and I highly recommend that you use the non-flammable "Chlorinated" type if you are spraying it anywhere near a running engine. The risk is small, but the potential results can be devastating.
(BTW, the Non-Chlorinated version makes great starting fluid).

Also remember, NEVER use Chlorinated brake clean on anything you intend to TIG weld.
