I typed searched for a detail build thread for a GenRight EXT Tank and didn't come up with anything. Decided I would try one and hopefully helps others out, will also show moving back axle 1", but with this tank, axle can be moved back up to 5".
remove the plastic mud flap below the rear quarter panel to get to the filler and vent hoses, then loosen the hose clamps and remove the hoses from both the tank and the filler neck.
remove the filler neck and it should look like this
cut exhaust pipe just before tank skid plate, to allow tank to drop down easily. If anyone has tried dropping the tank without cutting the exhaust, you know what a pain it is.
You will need to re-route the exhaust later due to the shape of the new GenRight EXT tank.
Place jack under center of gas tank and place some pressure on tank.
loosen four bolts at the rear of the gas tank and three bolts on the front of the gas tank. I used a 1/2" socket and 1/2" box end wrench.
remove all seven bolts and begin to lower tank very slowly.
remove the vent lines - there are two, or you can leave them connected and remove at t-connector
disconnect the electrical plug that goes to the sending unit, be careful not to break plastic clip.
use flat head screw driver to remove gas lines from sending unit. you can release gas pressure at the fuel rail like the instructions say,
or you can do what i did, before i ready the instructions, and pull lines, and catch gas into can.
now you are ready to completely lower the tank and remove.
here is the new GenRight EXT tank with Skid...pretty beefy. It is supposed to except the stock sending unit.
The skid is 3/16" steel i believe, and should provide 1" of extra ground clearance over stock.
Now it is at this point, that i have to do some other modifications before i finish the tank install.
1) i need to move the axle back.
2) i am going to do a tailgate drop-down conversion, which will require getting to the tub near the gas tank.
I thought about documenting moving the axle back in this thread, since it relates to the tank, but don't know if it will help many people.
I may just detail that in my build thread.
I did this install in May along with a bunch of other stretch stuff from gen-right. I was able to get 4" out of this particular tank with an 8.8 and SOLID diff cover just as an FYI for others. Very good product though! goodluck
