    One will work fine .
    Most of the milking problem is from being to rich if you are having that problem also.
    But it also will help with moisture and if you are running injection to help with the moisture you can open the butterfly to let some of the heat out.
    haven't tried it with a carb.

    I also run a hat with a vacuum pump some time i will fold up a towel and put it under the butterfly to let some heat out works good.

    I'm running injection on alcohol and a 4 vain vacuum pump. The breather on the separator tank was letting vapors pass thru the breather cap, making a mess around the cap. At first I thought I might have a problem with my engine or injection system. After checking everything, nothing wrong. I even thought about leaning my engine a little to help. I was told to put a dry wrist sweat band around the breather cap after each round. I ended up throwing the moroso separator away and ordering a Star Machine separator and haven't had any problems.

    I AM RUNNING THE ELECTRIC ZO6 PUMP WITH MOROSO'S OIL SEPERATOR, MY FRIEND RUNS TOP SPORTSMAN AND HAS BEEN RUNNING HIS FOR 3 YEARS NOW WITH NO ISUUES BUT HE IS ON GAS AND DOES NOT HAVE THE MOISTURE PROBLEM THAT COMES WITH ALCOHOL, SO I AM GOING TO TRY BOTH COVERS INTO A TEE AND USE A VACUME GUAGE TO MAKE SURE ITS DRAWING ENOUPH AND SEE HOW IT DOES WITH THE MOISTURE PLUS USE THE OUTHER RECOMENDATIONS I GOT ON HERE,,,

    I like running Brad Penn oil also. It doesn't mix as easily with alcohol as other oils, gives your vacuum pump a lil more time to pull the extra fuel and water out of your engine. It also has a higher zinc count than the regular over the counter oil, since they had to take out zinc and phosphorus because they were clogging up catalytic converters on the new vehicles.
