So here's how it is:

I drive a '99 B2500 std.-cab and live in Eastern Iowa near a corn mill, so there's plenty of Ethanol... plen-ty!

I know there were V-6 Flex-Fuel model rangers built, and the aftermarket current offers an in-line adapter to allow "pump-&-go" use of it on non-flexible models ( Advanced Fuel Dynamics Proflex ) so my question is: What years Ranger came with flex-fuel that have a tank I can swap (16.5-gal.) and what other fuel-exposed components should I consider swapping for this conversion? And any other constructive wisdom out there to share on it? BTW: I know mileage will suffer do to the BTU-content difference, hey... if it's a cheap, widely available high-octane option to qualm knock produced with how this truck lugs it's weight around with a 5-spd, I'll take it!
