If your buggy has the vacume operated fuel pump which is recognised by the 2 hoses going to it. The diaphram inside is spring loaded, when the piston is on its downward travel it creates vacume which sucks down on the diaphram thus allowing fuel to fill its chamber. As the piston starts its upward travel vacume is lost thus allowing the spring to release the diaphram forcing the fuel out of the chambet to the carb. What I need to know is 1) Do you have a nipple out of the fuel tank or the vacume pump with 2 nipples. 2) what is your compression is PSI.
