what kind of fuel injection system in a gmc sierra 2000 2500 truck. IS it a...

...digital multipoint injection? I want to convert my truck to e-85 and I need to know what to do to convert it. Do I need to replace gas tank, gaslines , fuel pump and is the fuel system compatible for this fuel. I am thinking about buying a flexfuel system for my truck. Please only serious answers

It should be. The General did away with that old antiquated throttle body FI long ago in the 80s. Check with your dealer. There's probably just a minor programming change to deal with the E85. I understand you will lose a little power and economy, so I hope you're not paying as much for the stuff. One poster here said she was saving an unbelievable 80 cents per gallon. I don't know.... 'nuff said?

If it's GAS VORTEC engine it is multipoint injection, inside the intake are the injectors they are assemble all together it looks like a spider with 8 legs depending on how many cylinders the engine has I hope this helps, I have a question for you what is e-85?

in 2000 you could get 5 engines, if your 8th vin digit is T you have a 5.3l vortec with multiport digital fuel injection if its a U its a 6.0l same injection as 5.3l, if its an R its a 5.7l with central sequential fuel injection (the one with the spider looking injectors), there is also a 4.8l and a 8.1l but i don't know the vin codes off hand. look under the hood there should be an emission sticker that will tell you what you need to know.

there is a change kit that upgrades that fuel injection system. if you are having problems it cost around $300 just to make it run good on 89.
