The manual shows a short piece of hose coming through the floor hole, but I dont see anyone that sells a fuel fine from the rubber hose up to the sender. So do I need to bend my own piece to from sender to hose? Hopefully this makes sense...Thanks! | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Is this for your '27 truck or your '41? | | | | | Joined: Jun 2012 Posts: 76 Shop Shark | | Shop Shark Joined: Jun 2012 Posts: 76 | sorry my question was for a 50 3100 series with cab mounted tank. | | | | | Joined: Sep 2006 Posts: 3,596 'Bolter | | 'Bolter Joined: Sep 2006 Posts: 3,596 | The line comes down from the tank to a shut-off valve it is really more of a nipple than anything just long enough (maybe 4-5") to come out underneath where the valve can be screwed on. Then there is a short rubber hose from that valve to the steel line running along the frame to the fuel pump. The hose is available from vendors but the valve is not reproduced as far as I know.

Is there a rubber grommet that goes in the floor in addition to the rubber sponge that goes around that line thru the floor? | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | There is a rubber grommet for the sender wire and ground ...pic... ...sponge...
