my neighbor was in the process of replacing the intake on his 89 k5 blazer with the tpi 5.7ltr engine. this was a crate motor so im not sure how it is listed as far as year model. as he was re-connecting the fuel lines to the intake, he broke one off on the driver side of the intake. he called around but was told he cannot get one from anywhere because they were discontinued. is there anything he can can do? does anyone know where to find one? is it true they are discontinued? is he just S.O.L? thanks for you help in advance
