Was wondering if anyone has been running a Mallory 250 gas electric fuel pump with E85 fuel. Holley that has bought Mallory couldn't tell me if there 250 pump was compatible. Tech gut said he would ask the engineers about it and call me back and never did.

I used a Mallory 140 from 2008-2013 without any problems.

I ran a holley blue pump on my 450 hp Chevy wagon over 15 years witout any issues. Didn't want to push my luck and upgraded to a Holley black this year and I carry the old blue pump now as a spare.

Just send it back to them for a alky conversion then you know you will be good, I did mine and the cost was not bad.

Do they still sell the methanol repair kit?

I had A Comp 250 on Alky and e85 w no problems untill I sold It.
