    Just bought a 359 and have a couple of questions. I was thinking of installing the Leak Defender fuel caps but wanted to make sure the non-vented caps will work properly. I see that the drivers tank has a rubber vent line running down the frame from the top center of the tank but the passenger side simply has a plug where the vent line should be. Does both tanks need to be vented or is just sufficient to allow level equalization.

    Both tanks need a vent to level out properly

    I HATE MY TANKS! THEY ALWAYS NEED FUEL! THEY SHOW EVERY SPEC OF DIRT AND ROAD GRIME! THEY ONLY NEED REFUELLING WHEN IT IS 110 DEGREES OR - 30! THEY ONLY NEED REFILLING WHEN WE ARE THREE DEEP AT THE FUEL ISLAND!

    I feel much better now that I've vented about my tanks!!! Thank you for this opportunity.

    Thanks. Does it matter how long the vent lines are?

    No the length of the hose doesn't matter. If they're Peterbilt tanks it takes a special vent that screws into the tank, they're available aftermarket a lot cheaper. Just do a google search for Peterbilt fuel tank vents and you should be able to find them.
     
    Redrammer99 Thanks this.

    Very few will get the chuckle factor there, but it rated highly for me. :)
