Auxiliary Gas Tank Installation
What is the end result of this? Let's find out:
Stock gas tank = ~18.5 gallons
Auxiliary gas tank = 11.5 gallons
Total capacity = 30 gallons + 5 gallon jerry can.
How far can 35 gallons take you? That all depends.
If you drive efficently you can easily squeeze 20 mpg out of a V6.
That's 700 miles. even at 15 mpg it's over 500 miles of range.
This is the 11.5 gallon auxiliary gas tank, manufactured by NWMP. I purchased it from NWOR during their october sale, i was told that i was getting the last one they had. i was very pleased to have it discounted $150. with shipping it was $416, money well spent. The kit came complete except for the instructions, but i sent an email to NWMP and they sent me the instructions, attached in a zip file. thanks Sharon!
The spare tire raising/lowering mechanism is used to raise the tank into position, makes it an easy one person task.
The filler is tucked into the inside of the wheel well, just outside of the line of fire of of the tire, but i can see this getting very dirty in muddy conditions.
these are the two lines going to the top of the main gas tank. one is from the intake manifold and is the fuel return line, the other is from the charcoal canister and is the evap. emmission line which gets disconnected from the main tank and hooked up to the aux. tank.
this is the main tank filler hose and vent hose in the wheel well, with the access pannel removed.
the vent hose is cut and a "tee" fitting installed with a hose running to the top of the aux tank.
fuel filter and one way flow valve
fitting that replaces drain plug on main tank (skid plate removed)
i chose the 11.5 gallon tank instead of the 20 gallon tank because i still wanted to have a spare tire in this location.
yeah, it hangs down a bit, but it would be alot worse without the lift springs...
Beefing the main gas tank skid plate
While i had the skid plate out i figured i might as well beef it up.
i still had about 7 feet of 2" wide, 1/8" thick steel strap laying around, so i put it to good use.
all welded up, ready for paint.
Of course after i paint it i find that the fitting on the gas tank interferes with the skid plate, so i had to clearence it so it will fit.
basically i just made one cut and beat it with a large hammer. then welded a thick piece of sheet metal on the under side and welded the crap out of the top.
