I guess I was more worried about fuel sitting in the vehicle tank for 6 months.
My tank has a filter and then a redundant water block filter. I've done this for decades and never had even a hint of injector problem. Cheap insurance. It's the only way to fly.
What do you use for a water block?
I recently heard there is a better water block than what I have been using.
I have been using the tank filters with the water trap on the bottom.
I use CIM TEK filters. One is a combo filter and water trap filter. It does not have a drain at the bottom but I understand it stops flowing when it's full. The other is just their regular filter and I run them both in line at the tank. Both are spin on cannister filters. The water trap filter really would be enough but I figured what the heck and installed both.
They were bought at either Shoup Ag Parts or Sloan Ag Parts mail order.
The same brand I use for the most part. I am dealing with Shoups now. They do not always stock what I have.
I used to deal with Meier OIL until they sold out to FS. FS shut down their filter division. FS Sucks.
