I got these parts with other items I bought and not sure of the history or if they are working units. There are two cool fuel systems, one looks to be all there, but has bad fuel lines. The other is in pieces and has good fuel lines. Looks like you could make one good unit and rest for parts. Also included is a fuel filter housing with some sort of electric fuel pump attached. Sorry don't know much about the parts. I'm asking 125.00 obo plus the ride.
