For oem applications, I like to use this stuff. The nitrile inner liner makes it safe for e85 also. also for fuel injection clamps use oem clamps, I never have good luck with the aftermarket parts store crap. I also like to use pinch clamps for rubber hose applications as they're more secure, but it does require a tool to clamp down. They're also limited in range.
