RE: Do I need a pump
Jaka,
The venturi in my engine is .342" ( small ??? 8.68mm ). My tank is as high as is possible. My engine has been lowered. The spraybar is 3/8" below the top of the tank. The tank is as close as possible to the firewall. I tried that screwy three line, special; clunk system and It does not work worth *^%@#&&. The pressure tap on the the exhaust stubb area on the silencer is where K&B put it. I moved it to the muffler body with no luck.
