I need to replace the fuel filler neck on my ford ranger the wheel base is 126in all my mechanic and I can find is 112-118 in it’s a 2000 ford ranger xlt v6 flex fuel 3.0L
I was told I need a step side/ flare side but I don’t really know anything about vehicles does anyone know what I should buy?
 
As far as I know, there should be 4 different offerings that should work. the stepside/flare side and Fleetside model of the Ranger should have two different types at the most.

Stepside/ flare side refers to the bedside design. if you have the fender bulges on the outside of the bed and narrow inside, that is the stepside/ flare side bed. it will be 6' long. the filler neck will be shorter, as the gas door is closer to the fuel tank.

Fleet side is a regular pickup bed with the fender bulge inside the bed and the body lines are straight and line up with the cab. there is a 7 foot and 6 foot version, both should have the same length filler neck.

the two variances that you might get per bed type are flex fuel which if you have a 3.0 you probably have the flex fuel, and the non flex fuel if you have the 2.5 four cylinder or the 4.0 six cylinder. that being said, if you do have the 2.5 or 4.0, the flex fuel neck should be fine.. if you have the little green/.yellow/ black corn looking emblem on your tailgate, (and you have the original tailgate) you have flex fuel.

So as long as you have one for a stepside and it at least is flex fuel, you should be ok.

if there are any differences between the three wheelbases (regular cab shortbed, regular cab longbed, and supercab) I am not sure what they would be concerning the fuel neck.

126 in is a ext cab/shortbed i think. I would just order one for a shortbox.

I believe it is a step side/ flare side it is a flex fuel for sure. ( v6 flex 3.0 )the wheel wells are bulged on the outside and has a little step up to get to the bed (also bulges on the inside not sure if that changes anything) KBB vin check says it’s a supercab it’s a 6 foot bed, I don’t use flex fuel in the truck though I use just regular gas so would that change anything either I assume the flex fuel fuel filler neck would have a slight variation in the build where as just a regular would not so if I’m not using flex fuel I regular step side should be fine

I believe the filler neck is the same regardless as to whether the truck is a flex fuel model or not. The difference is in the fuel injectors and control module that feed the engine. The fuel lines and seals are also made of different materials to deal with the high ethanol content. The filler neck, on the other hand, should only be exposed to fuel for short periods of time. I wouldn't be surprised if all of them are made of the same ethanol resistant material in order to minimize the number of parts in the system.
