Mr. Funnel Fuel Filter comes in four different fast-flow models.
Models differ mainly on flow rate. If your need is to transfer five gallons or less of fuel, then the F1 and F3 are for you.
If you are transferring more than 5 gallons, then the F8 and F15 are right for you.
Our F15 is our fastest flow model at up to 15 gallons per minute!
