I have my DW 72LB injectors for sale, that came with my Whipple stage 2 kit. They are in great shape, and never had any issues with them. They have 7k miles on them. I just recently switched over to e85, and went with ID1050's upon switching. These 72LB injectors only saw "standard" 93 octane...
Just a random fyi for the thread.. Roadheavers has their dual gt350 pumps return fuel systems back in stock. No clue how many he has in. Dropping mine off tomoro for install.
