Product ownership: A year or longer

Purchased from: Butler Performance Inc.

you've got to understand, i was chasing problems that i thought were 'carburetor' problems for more than a year. issues with a leaking gas tank led me to butler performance (thru street outlaws, tks big chief), for a new sending unit since the old one was fried. the larger diameter pick up, then fuel line supplied enough fuel volume and pressure to the carburetor, and after some tuning, my 'carburetor' problem was gone. it might be a little pricey, but it works!
