I cannot seem to find this info anywhere on the size of the stock pumps?

I am trying to plan an upgrade for potential e85, but I also don’t need a triple 465 setup either.

can anyone fill in that blank on stock size and if lower than 255’s , ideas on how far I can push twin 255’s with corn?

This KB article might help answer your question.
If I read through that correct, either the stock 13/14 or the stock 07-09 pumps are 189LPH each? One section just says GT500, while all the way at the bottom they break them down differently, so I assume the 189LPH is for 07-09.

So if dual pumps together flow about 25% less in the same assembly, dual 255's would basically be equivelant to stock 13/14 pumps then correct?
PS: I already have a KB BAP, so I would be overdriving the new pumps as well

This may all be a wash anyway. I looked up info from Walbro on the GSS342 and they state these are not reccomended for E85. Wonder why Fore even gives the option for non E85 compatible pumps.

I would call Fore and ask them, they are extremely knowledgeable, and some of the pumps are now compatible with e85. They can walk you through a good set up.

They do work, but will wear out faster. I currently use them with gas and E85 i have had to replace pumps once when let E85 stay in the tank over a winter.

thanks for the info. This solidifies my decision to just hold off until I can find a deal with some TI pumps.

I did not want to waste their time as I was looking at a preowned setup and was not looking to buy directly from them. If I was buying new, I would have no problem asking them though.

I totally understand, they are just a wealth of knowledge when it comes to fuel. We have called them a few times to pick their brains. I would recommend them to anyone with fuel related questions.
