What Fuel Pump Are You Carbureted E85 Guys Using???

I ran e85 in my 85 d250 and it seems to love the stuff... I tried some once as ab experiment, figured I'd need my son with his truck and trailer before I got 3 miles from the gas station but I was quite surprised. I put 1/2 tank in then topped it off with 87, ever since that day when I had a lot of windshield time in it id do the same especially if I was over in Indiana where e85 was (at least back then) much cheaper vs the price of reg 87 than it is here in Illinois
I have. 1 12 Dodge 1/2 ton that's actually rated as flex fuel but for the difference in economy it ain't usually cheap enough for e85 here. I do run a tank occasionally in the summer as a"cleaning agent" for the injectors and such
