hose question for TBI system

would -6AN hose be big enough for the pressure line of my TBI system? also, would i hurt anything if the return line was the same size as the pressure line?

Re: hose question for TBI system

Yup, you'll be fine. I run -6AN for both feed and return. I also split a -4AN line off the feed line, for the nitrous system, I have no issues, -6AN will flow enough to support 400+ HP.
