Today I installed the gas tank. First I jacked up and drained the old tank, then went to removbe it, the nuts that hold the tank straps are 14mm. I recommend having a ratcheting open end box end wrench and a ratchet with extension and a deep well 14mm socket. Screwdrivers to remove the fuel lines, unplug the electricsand lower it down. You will have to pull it off of the filler neck, even though the clamp is loosened. Oh, and take pics of everything so you can refer to them on re-install. Once it was half way down, I was able to remove my singular vent hose. To put the new tank in, the rubber pieces I bought for it did NOT come with a sticky side, so I used some of my 3M VHB double sided tape and got them on. I then cut the plugs off the ports I do have and then just put the tank in the hole carefully getting the vent hose in and then getting one strap up and held on to take the weight off then push/pull the tank to get it in the correct spot and then get the filler neck started. I wasn't able to push the filler neck on...just able to get it started, so I put the other tank strap on, the closest to the end, and as I tightened it down, it pushed the filler neck on to where I needed it! Then it is just a process of tightening clamps. I found that instead of a screwdriver, an 8mm open end wrench worked better for tightening the filler neck clamp. I noticed that the drain plug in the new tank is 18mm, and the original was 19mm by the way. Putting the sensor in was easy enough, but I ended up doing it twice and draining the tank twice, as the ground pin, or the pin with the rubber at the base needs to be on top of the other post. When I filled the tank up, the gauge was reading backwards, so I qucikly drained the fuel, tapped the ring off & flipped the sensor and tightened it back on. Everything worked great from that point and Bob's your uncle . I have attached some pics of the days work. See attached.
