Bought this mainly because of the built-in fork pockets so I could move it around with the tractor. Those fork pockets are so close together that the unit feels a little unstable when on the forks. Seems that it could have been designed with the pockets a bit further apart. As some others have commented, everything was loose when this unit arrived. Be sure to check that the filter, motor, and all screws are tight before using. Also, you need to be very careful when attaching the hose to the pump. The o ring that is used to seal this connection is easily deformed when tightening and will cause a leak. I think a better-quality swivel connection on both ends of the hose would be an improvement. The hose would wrap up for storage easier then also. I saw some folks used Teflon on the hose connections. I did not and have no leaks.
I didn't see any other comments about the fill/breather cap. As should be expected, it will leak some on your way home from the station through the breather. I pack a few paper towels around it to soak up some of the leakage. My bigger concern was when using the pump. The breather should allow air in as diesel is pumped. The breather on my tank doesn't. As I was pumping fuel, I noticed the sides of the tank sucking in. I had to unscrew the fill cap to allow the tank to breath. You shouldn't have to do this. I am sure that this makes the pump work harder than necessary. I don't think it pumps 10 gallons per minute, but maybe that is because it was trying to implode the tank. You can realistically only get about 100 gallons in the tank. That is okay, but I do not know why they call it a 116-gallon tank. That is just not going to happen. In the end, it does what I need it to do. However, I think if I had to do it over, I would put together a steel storage tank and just strap it to a good pallet so I could move it around.
