Question for those with an Auxiliary diesel fuel tank

My bed tank is not plumbed in, it has a hand pump on it with a very good filter. If I had to change the truck filter, I'd pump fuel from the tank through the tank filter.

I use a hand pump on my bed tank because I have to remove it a couple of times a year to get other loads in like I'm doing today. I have a second matching tank that I pump the fuel into.

If I had a bed tank that was plumbed in, I would have a filter on it.
