Auxilliary Fuel Tank installed 30 gallon

[steakman]

As a guy that drives quite a bit and goes into areas where diesel is $1.00 or more a gallon more than where I live, getting an extra capability for fuel was a hi priority.

I put this tank in about a month ago. Aluminum Tig welded 3/16" plate with 1 baffle. The fill tube is a 1/2 coupling @ 2" NPT and the actual fil tube itself is 2" ABS piping-it was the cheapest, drain and vent fittings are 1/2 couplings @ 1/2" NPT.

Tank sits on 1/2" hi Density foam and is strapped down in 3 places..it doesn't move.





In the second pic, you can see a small bit of harness where I had originally planned a solenoid with an on/off toggle in the cab. I could not find a 1/2" or 3/4" solenoid cheap enough and as such decided to go with just a manual valve. As for the wiring harness, I am planning to add some "in box Lighting" soon to make use of it.

For filling the main tank, I plumbed into the fill tube by cutting into it and inserting a 2" barbed nipple from Northern Tool Ltd. IN retrospect, the "kit" from N Tool was not worth the money and the only thing I used was the 2" nipple - I'm thinking that a guy could just cut some 2" ABS pipe 5" long -rough it up and dbl clamp it into the fill tube. That should work just fine as there is no pressure there whatsoever. By tapping a 1/2" hole to accept a 1/2" X barbed fitting you could easily duplicate the N. Tool Barbed Nipple and save yourself 100 bucks.!

Here is where I installed the 2" N Tool nipple







All of the threaded connections are teflon taped and then pipe doped to ensure no - leakum.

This works like a charm. All I have to do is open the ball valve and let er go...takes about 30 miles of driving at 70 mph and then I pull over again and shut off the valve. Not having to use Jerry Cans - Priceless..!!

interesting....how much did that end up costing all together?

The tank ran me about 500 CAD - fittings and such another 150. The Northern Tool Aux Tank kit was 100 CAD and part of the 150 I noted...not worth it at all.!

Thanx Mike. It's not a huge tank, but it works pretty good for me and stoppin at the side of the road to fill up with Jerry cans just wasn't my idea of cool if ya know what I mean.! LOL

Still those jerry cans saved me over a 100 a month since last October.

Go to Princess Auto, they have a cheap 12 volt solenoid that works with your fuel system. I have been running the same system with the 12 volt solenoid and works great. Run mine with a 300L slip tank. Make sure you wire it to a 12 volt key on only in your fuse box, this will shut off the solenoid when you turn key off. I keep the solenoid in the box to keep it out of the mud & snow. The only problem I have found is if you leave the solenoid on and you fill the main tank to much it will make the fuel guage go to empty, just have to shut it off & run a few km's and it will back to normal.
