[basketcatch19]

well heres a tough one what size fittings are on the manifold for a tbi fuel inlet and return? it's for a 91 blazer 5.7 350.

IIRC they are oring fittings. Good luck finding some of those. I used the hardline that came with the tbi unit then spliced it into the stock hard line with some rubber line.
