Well I'm about to do the same thing. .093 is a 3/32 you need a long drill bit I found mine @ fastenal I also got 1/16 and 5/64 to go in steps since I didnt know what the OE size is.
Looked down them more times than I can count. Your not gonna gain any flow and your more than likely gonna cause a lopey idle and possibly hurt driveability and maybe power as well. Same goes with larger lines. They don't help power on these VP trucks. All they do is cause lopey idles and poor driveability.More fuel flow. If you have ever looked down a stock connector tube you would understand. I dont even see how fuel got through there!
that would be like saying having injectors with bigger holes in the nozzle wont do anything. a restriction is a restriction, it means less fuel.Now this is really, something drilling out the hole on a threw connector and figuring you will get more flow. you are talking about thousands of pounds of fuel pressure and you are worried about restriction, I would be more worried about after drilling that it will crack. Mercedes used the same set-up on a 906 and they can and do crack them. PLEASE DYNO before and after, I can't see how there is any benefit. PLAY SAFE
