    I used a mogas sender from the same year make/model and made it work. as long as it's the right size for the tank, you're good
    ebay has plenty of them pretty cheap, since we have to mod the sender to fit the large tank it wasn't extra work.
    I had to snip a new notch for the tabs to properly clock the sender in the tank

    I think this one works for just about all Bull, Brick, & OBS. "Please return your tray to the upright position and remain in a seated position before looking up price"! IMG_6876.JPG IMG_6877.JPG

    so im thinking im goin to use the sender i have. if i do i plan to have a fitting soldered into the tank for a return line. i also an thinking i will remove the vent tube from the filler and have a 1/2inch fitting soldered into the tank to run as a new vent line with a filter. then i can will tank quickly without it shutting the pump off every half gallon. i plan to use the universal selector valve as i found a diagram on how to wire it in.

    From what I recall, the bull and bricks used a different wiring plug on the FSV. I don't think this one is that universal.

    drill a hole and solder a steel line to fab a return

    I am late to the party, but why not solder the return into the sender, like the stock ones have?

    i placed it about an inch higher on the tank.



    new problem...removed front tank. lines and selector valve. new pumpo is about 2ft from rear tank....on frame rail. i repaced the last on when i did the tank install. even thought it was only 3days old. keeps running dry at the filter on motor...then i have to stop and bleed the system when it dies. after about a mile

    go home and pulled the injectors from my 7.3 ive got as a spare...great shape..bb code. got new line and real fuel injection clamps for the return system. also going to remove the return line going to filter head. all that should stop the air getting in

    injectors are in. new hoses are on. only 1 leak from #4 injector..very small but drove it and now it dosent bubble. so assume it just had to get seated better. was able to drive a few miles, i even drove barefoot so i could feel the motor better. little loppy at idle but smoth under power
