I will be converting to E-85 before to long. I need some suggestions on what pump and injectors to use to compensate for the 30% added fuel consumption and not starve the motor. The motor will be high compression with a stock intake, stage 2 will be an eddy with spray. I have heard I need to replace the stock pump with a alky friendly high volume, but I have also heard the twin Cobra pumps would work, so im not sure which way to go with the fuel pump. As for the injectors, I was thinking id be fine with a set of Accel 48lbs. I dont know if I need to up the fuel pressure with an adjustable reg either. If anyone has some experienced info it would be greatly appreciated. THANKS GUYS!

Anything guys?

anything rubber that is not compatible with e85 will have to be replaced, and i beleive you will need to have it dyno tuned to get the proper fuel trim tables. it will most likely cost more than any fuel savings from e85, if thats what you after. unless you plan on driving it for 200k miles. then it might pay off.

From what I understand all vehicles made from like the late 80's were compatible with ethanol fuels. I plan on having it dyno tuned after the motor is done, I just havent figured out what size pump or injectors I need yet so I dont starve the motor for fuel. I am going ethanol because its cheap and has the octane rating I need and it likes the spray.

Well they say it takes ~30% more fuel like you said. Figure out what kind of power you'll be making then multiple it by 30%.

It's difficult to suggest anything when you don't give any info about your build/power numbers.
