fuelvaporhose.jpg Bronco Tank Vapor Hose

It takes slightly more than a foot to connect the steel vapor line on the frame to the rollover valve on the tank of '80-96 Broncos.  If the hose is too short it can break the rollover valve.  The valve for 5.8L trucks costs over $100 new, but it's getting hard-to-find.

This hose is Gates 4219XL, which doesn't seem to be made any more, but other fuel/vapor/emissions hose IS made. Use 3/8"(10mm) fuel/emissions/vapor/PCV hose for the vapor line between the tank & charcoal canister. Do not use coolant, vacuum, ATF, PSF, or silicone hose.
