Gulf Coast filters, both the JR that uses a toilet paper roll and the original model that used a roll of Bounty paper towels are excellent filter devices. I used the paper towel version for over 20 years, with maybe an annual (preventative) change in the paper towel roll. We carried 1,500 gallons and filled up maybe every other year. I had a system where I could recirculate each tank through the filter and return to the same (or a different tank for transfer). Once a year I'd recirculate each of the 4 tanks for 24 hour. Fuel was always clean and pink. Can't say enough good thinks for the Gulf Coast Filter. If you have the height, go with the original paper towel one (you need at least 2' above the top of the filter, higher is better when changing the roll of paper towels). If you don't have the height, the GC JR will work fine, you may just have to change the roll of toilet paper a little more frequently depending on how dirty your fuel is, but changing is easy with either one.
