I have excercised the vapor lock demons from my bronco! I have installed an electric Moroso 110gal/hr self regulated fuel pump and rerouted the fuel lines along the outside of the passenger side and up to the carb - cutting out the mechanical pump altogether! The acid test came yesterday in 103 degree heat on I-70 through Denver. Traffic was backed up due to other over heating cars along I-70 as I sat in stop and go traffic for almost an hour! Not once did the bronco act like the gas was carbonated!
