Alcohol & Evac System (collector tubes)

[CDB03STX]

Since this pertains to Drag Racing, thought I should post here...

ZAPSTER could be of some assistance

I'm in the need for some knowledge dealing with a simple EVAC system setup into the collectors on a drag truck. Changed my Uncles truck over to Alcohol and now the need for an EVAC system before the alcohol contaminates the oil. I tried to make something but it didn't work...It actually blowed instead of sucked. I didn't do a whole lot of research before hand.

Some of the racing forums actually say the collector setup is almost useless and most are running vacuum pumps which is very costly.

Does anyone have any clue or suggestions as to where I might find some good info with pics...

Thanks CDB
