Fuel injection hose that doesn’t suck

[Chickntrk]

I assume you are talking about pickups? The K5's and 'Burbs were all braided flex line with the GM o-ring connections. As I recall the flex steel lines are teflon lined (never cut one open myself), so should be resistant to ethanol.

I was talking about the pickups, however the same principals apply to all the early TBI stuff across the brands, it’s a low pressure system so if you’re replacing factory stuff steel or stainless steel and rubber hose will do…beyond that it’s just personal preference on how it looks or brand…I like being able to source parts from local stores rather than have to wait for summit or jegs.

They’ve even got the 4L80e cooler lines I need. Nice.

3/8” stainless fuel supply line and 5/16” stainless return. Good enough? Then whatever little parts I need to to adapt to the fuel rails.
