Boyd Welding-67-72 Rear Mount Aluminum Tank

[VA72C10]

I'm putting my filler in the driver's rear stake pocket with a pop up flush cap from a motorcycle. Will that 3/8 check valve down on the tank work or will I need to run the vent up to the actual fill neck?

I would contact John Fabris on that one, he did a similar filler like yours. You are talking about a vent for filling, im talking about a vent for draining. If you put a non-vented cap (like the flush filler) then you will have to add a vented check valve so that the engine can "drink" without cause a vacuum lock. More than likely you will need both.

Air has to come out when filling at the pump and air needs to come in when running the engine.. the different locations of these keep them from spilling an liquid during normal driving. Everyone also knows what happens to gas in a non-vented plastic container, it swells and blows

Count me in for a standard. Have a few questions though... I am gonna flush mount a ventless cap in the wood bed, am I going to need a second bung hole for two vents or is the one hole ok. Also I need the filler neck to at least be somewhat centered in a wood plank does anyone know for sure how far off it is on a fleetside?

here's what I'm laying out for a steel bed, with EFI.

I sent this to Dave to review...anybody else see something here let me know.....I basically took msgross' drawing and tweaked it a bit.

My measurements would put this about 1/4" clearance to the bottom of the bed cross sills. So you could move the side flanges down to 4" if you wanted it TIGHT against the bed. I left some room to run wires if needed.

capacity calculates to 19.6 gallons BTW.


Thanks,
Andy

Looks good and the side exit is what I would need. If an inch was taken off the height that would also work for me. I don't mind losing a little capacity for ground clearance....
