Aux Fuel Tank

[LeveeLiving504]

Would anyone have any objection on mounting this 40 gallon tank on top of the generator?

40 gallons of diesel fuel would weigh around 275-280 lbs. depending on temperature.
Add in the weight of the tank and mounting hardware you are well over 300+ pounds.
That might be a bit too much weight on top is my thought, but I am not the expert on what it can safely hold.

Also what is your plan on removing the top cover when it's time to service something?

I would drain tank and remove.

Do you have an easy way to fill that aux tank? Might not be any fun lifting fuel cans up that high.

Not a concern. I’m cramped for space so putting it on top will give me clearance I need in my alley way.

I object.
Your 2nd picture has the explanation about heavy objects on top of unit. I would set the fuel tank on a moving dolly
( https://www.homedepot.com/p/Milwauk...niture-Dolly-33700/100057209#product-overview) and roll it around to where I wanted it. As others have pointed out it will make maintenance and refills much easier.

I have a cart picked out at Northern tool that has a flat top and will hold 500 pounds. That was my first choice. That option allows me to siphon out my truck if I run into a pinch and also to off load fuel into my truck to cycle it out. This is why I like this forum I had my concerns just wanted to hear from some others.

It appears that I've got a little more room than you do, but this is what my aux tank looks like....very similar to what we're discussing with mounting your tank on a moving dolly:

Do you have any issues with the tank being at ground level and pumping into your day tank? How long is you hose? I would like to put a water separator in-line. Do you think the on board fuel pump will pump through the filter? Mine would be higher than the day tank and would be a bottom pick up tube in the tank. Thanks

One potential issue with mounting a fuel tank higher than the day tank is the chance it could gravity siphon fuel into the day tank even after the unit is shut down. You would lose all the fuel in the aux tank onto the ground and into the housing of the generator.

So you would think a low boy dolly would be a better choice?

Gonna go and pick this up and mount on the bottom deck. I’ll have a roof over the tank and the cart will allow me mounting possibility’s for my water separator.

No issues. Works well for me through the ~25ft fuel lines that come with some generators and the ones I've fabricated. I have another tank that I've installed a water separator on and the pump has no problem with it. It is better to remove fuel from your tank through a dip tube that enters tank from the top. The small space between the end of the dip tube and the bottom of the tank will prevent pick up of most of the debris / rust / dirt from the bottom of tank. If by bottom pick up tube you mean a simple drain you can get a lot of debris plugging up your fuel filters.

Very nice. I have the stock hose, but I’m going to get some made with the proper fitting. Thanks for all the info.
