Auxiliary fuel tank and gravity vs electronic pump

[chevyman94]

Hey guys I have a diesel 2022 Silverado 3500 High Country the crew with a 8 foot bed. I have my toolbox semi installed for a 60 x 10 x 19 tank at most right now to go under the tonneau cover I have on it and behind the box.

My uncle has a 2014 GMC 3500 crew 8 foot bed with a gravity fed system with a shut off valve.

Which system would you use and why also any recommendations in advance on what electronic fuel pump systems.


I am leaning towards the electronic as I have 5 up-fitter switches in my cab and would like to use them. My uncle likes the kis system

Any recommendations on a pump set up such as a brand?

Nothing complicated or expensive. Here's one https://www.amazon.com/Electric-Transfer-Universal-Pressure-2-5-4psi/dp/B07JPDZC4M

Go read the other thread just started on this in Tech I believe. All different options discussed.
You’re looking for an “excuse” to use switches in your truck?? Lol
Not certain why you’d need to pump the fuel since gravity works.
Keep it simple and best application for your use.

Aren’t you trying to start an argument, or just typical passive aggressive response?

I have several and I prefer a completely isolated system. I have a 4 hour bladder so stopping to spend 6 minutes to transfer fuel is no problem. The greatest advantage for me is it can be completely removed to haul large loads or place in a different truck.
