I am currently running pump premium in my street/strip car. Ever since I had my heads milled I get detonation under full throttle on pump gas. I would like to know if there is a place I can send my 850 demon to be converted. I also would like to know fuel pump requirments and any other info that may help. There are many e85 pumps in my state so that is a plus. I was thinking of running a bigger fuel cell for road trips since I will use more e85 then gas

My current fuel set up is 16 gallon cell.#8 fuel line with return. Edelbrock/essex 160 gph pump and #6 lines from regulater to 850 mighty Demon carb.12:1 compression. Ive also heard about spark plugs needing to be a different heat range?

You can send it to Quick Fuels to have them re-work
it or look in the arkives for the post that was just
moved over there. If your fuel pump can handle 30%
(minimum) more flow it should work, the rest of the
stuff should be fine
