As with any new project I work out the bugs as I find them. Filling the truck last night I found that the tee I inserted into the vent line for the transfer tank , served to restrict that and slow the filling for the main tank. Not acceptable.
I also found the during a transfer while traveling, the engine would stumble after a little while. I don't know what in the vent system might be contributing to this, but moving the fill line is a must now. That was the second strike.

I picked up a copper 1"x1/2"x1" tee and a brass barbx1/2" sweat fitting. This tee is cut into the fill tube for the main tank. I used some braided stainless line I had lying around this time. It held up well on the last truck too.




I put a splice in the vent line, so it is free and clear as it was stock. This should be a better solution and probably what I should have done to begin with.

The gauge is now set for 18 gallons when full. I think it is all where I want it now.

good work....


You make feel like a slacker
First you'll lose your mind
then any free cash laying around
Awesome mods will bloat your credit limits
Acting like a crack addict, refinancing your home, farm out the kids......
You'll cry yourself to sleep, stuff like, must get new rims.
Lift it skyward or drop it like it's hott.
Important questions like, polished or chrome, will shadow you day and NIGHT.

The cold slowed me down some. Highs around 20F and lows in the single digits tend to slow my enthusiasm for working on vehicles. :uglystupid2:

Finally made it to the low fuel light:


(cruddy cell phone pic)

564.9 miles when the light came on. I filled up at 569.6 miles. The main tank took 27.2 gallons to fill it. That leaves me about 4 gallons. That is a comfortable cushion. I can see 600 miles being possible. The auxiliary tank was indeed empty taking 18.2 gallons to fill. Total fill from the onset of the low fuel lamp illumination was just over 45 gallons.

Mileage on this tank was 12.5 mpg. Lots of winter driving conditions and warm up idling time. A good worst case mileage scenario.

I'd make that 10.5 mpg for worst case, that's still 500 miles. Translated to all highway I'd say 800 miles is possible with 45+ gallons.
