What do you do with the quart of gas in the pump when you lift it out? That is the thing I was trying to get ideas to solve. I had the bed off and the bed tilted up, I couldn't drain it by tilting it as I lifted it. There is always too much gas in it to not make a mess even if I am pouring it back into the tank hole. I don't expect to ever have to do it again. I was just wondering how others handled the gas and made the thread so people who have to do it can find some ideas.

Siphon? Either that, or have some cat litter around to soak up the mess.

I had to pull mine twice. First to replace the old one, second time I thought the new one had a bad sender. I never put any thought as to the gas in the pump it self. I thought everyone had a 5 gallon bucket laying around. Anyway if you don’t, grab a 5 gallon bucket from Home Depot and pour the gas in it and then pour it back in the tank where the fuel pump came out of or pour it in your lawn mower tank.

I just did that job. First, I removed the 8 bolts that attached the 8 foot bed to the frame. 2nd, I removed the screws holding the fuel tank filler to the side of the bed. Next, I got one helper to get on the passenger side front of the bed and I was on the driver's front side of the bed. I had a 3rd helper with about a 4-1/2' 2x4. While myself and the other helper raised the front of the bed at an angle up in the air, the third helper placed the 2x4 under the center front of the bed while it was raised into the air. Once the 2x4 was in-place, we lowered the bed onto the 2x4. This allowed plenty of access to remove the fuel pump assembly from the top of the fuel tank. The bed stayed in-place in the rear due to the rear bumper. I used a small electric fuel pump and 5/16" rubber hoses to pump out the old gas from the tank to check for and clean possible debris in the fuel tank before installing the new fuel pump assembly.

Once you place the new fuel pump, be sure the sending unit arm (float) is free to rise and fall and does not rub against the side of the tank. This is a common mistake that causes people to have to go back and rotate that fuel pump. Your fuel gauge will go squirrely on you if that float rubs against the side wall of the tank.

if only I had thought of that HY HF has a small pump that I use to fill my trans on the D50. I figure that might work to empty the pump, but it would probably be a one use thing with gasoline.
FatMike, that is what I had to do. I bought a new one to "fix" the gas gauge. Turns out the one in there was put in wrong, I could have just turned it 90 degrees to put the float arm forward and would have fixed it. Then I broke the overflow valve. When I oput the new one in the same problem existed so I knew it must have been the position of the float arm. I ended up finding one at a JY that had just come in and they gave it to me straight out of the tank and that is the one in there now. I ended up finding a fix for the overflow valve in the FAQ, so I fixed the "new" one and now I have an extra.

I did something similar. I had no help. Once the bed was unbolted and free, I put a 4x4 on my floor jack and positioned it on drivers side, front corner, of the bed and jacked it up. I put a couple big wooden blocks between the bed and the cross member. Then I did the same to the passenger side, rear, jacked it up and put a 4x4 between the bed and the frame. I repeated this process once more, front and back, until the bed was raised high enough to get the fuel pump out. One man operation. Took some time but no heavy lifting. Note, don’t position the jack under the side of the bed, only on the inside the corners. Otherwise the weight will bend the sheet metal on the bed.
