Fuel Pump
These simple mechanical pumps rarely fail. Since the pump is right near the carb, it sucks gas from the gas tank - there is no electrical pump inside the tank pumping gas to the carb. A stock mechanical fuel pump puts out ~7psi, but can be regulated to about 4psi for better offraod performance. quoted from http://www.bluebassdesign.com/boonin/carb_faq/

Well, that's a start. At least I know that if I get the regulator and it doesn't help with the stock carb then when I switch to a Weber I will definitely use it.

if your aap had a pinhole in it(what usually happens when it fails) it would run very rich, black smoke, ty mpg.
