Auxiliary Gas Tank Install on Land Cruiser

Post by unwiredadventures » Tue Jan 13, 2009 11:43 am

Back in October, I had scheduled a trip into the area north of the Grand Canyon called the Arizona Strip (Parashant National Monument
). This trip would be almost a week long with nearly 400 miles of driving off the pavement and away from any services.

I needed better range than the stock gas tank and jerry cans.

I drove out to Man-A-Fre and picked up this kit: Man-A-Fre LONG RANGE 24 GALLON 80 SERIES AUXILLARY FUEL TANK

I scheduled an afternoon for the install. It took much longer, see below for more:

Original filler neck needed to be cut to be removed. Note: you need to cut this carefully since part of the bottom is used to connect to the new filler. I disconnected it from the stock tank first before using a cutting wheel. First cut must take place while in the vehicle since it's shape prevents complete removal.

Filler removed:

Switch mechanism is hitting the inside of the fender preventing switching. MAF gave me a bad filler neck:

No worries, Spector off road is not too far away (from my home). I picked up two filler necks from Spector Off Road. The one on the left was ready to install but has no unleaded nozzle restrictor. The one on the right has the restrictor but the previous owner did some modification to it, so I need to get it fixed and installed before my next smog check.

Correct filler neck purchased from Spector Off Road on the left. Bad one from MAF on the right:

Photos of the tank installed. Note: It's a Kaymar Rear Bumper:

Aux tank guage. Manual pump switch to pump gas from the aux tank into the primary tank. When you turn on the pump the yellow indicator light is on. It's odd to see your main tank gauge start rising while you drive.

Pull out to fill the auxiliary tank. Push in to fill the primary tank.

The kit comes with a fuel transfer pump that has no easy way of mounting. So I got a different electric fuel transfer pump from NAPA Auto Parts, part P74019 for less than $50 since it included a better mounting solution. I mounted it near the drivers side rear spring using an existing threaded hole.

All in all, I'm extremely satisfied with how the system works. It's wonderful to have nearly 50 gallons of gas on board. It makes for less worrisome travel with the much longer range.

The system worked perfectly on the week long trip on the Arizona Strip.

Here is the LC in Arizona very far away from any gas stations:

Nice! I have a 2 year old 18 gallon foam fuel cell from Fuel Safe i was going to use for my 280zx V8 race car, but i ended up selling the project. Ive been thinking about installing it in my Pathfinder as a secondary tank to refill the primary tank via split fuel filler neck. Do you have plans for taller or thicker springs for a full fuel load?

I found this general purpose tank at Northern Tool. It may be good for a pickup truck or other mounting.

My current springs were designed for a heavy load. Before the tank and rear bumper, the truck had the "stink bug" look. Since the tank, it now sits more level.

However, I think my current springs are a tad too soft. Once I'm done with adding a winch, 2nd battery and skid pate, I may swap out for some heavier duty springs.

Very nice. Officially jealous.

How does this impact passing california smog? I have heard there are issues with not being able to seal the system tight and it fails the pressure test. Not to mention the visual inspection.

It should be fine because its just adding capacity with another sealed unit. Overall, the system is sealed.

It's sealed. No vacuum leaks.
