Thanks for the reply Roger

i have a gm tbi from a 5.7 L 8cyl (has blk orange marking on the injectors) i am going to put this on a 4.2L inline 6. can i use these larger injectors without suffering in performance or fuel economy, or should i get different injectors?

i'll check on that, thanks

does any one have a part number for the rubber fuel pressure diaphram for an 89 GM TBI. i bought an ac-delco rebuild kit, but it did not come with it, and i have had a hard time finding one.
Thanks
