I bought these 720cc injectors used. I know they were used on a turbo d series before........but they aren't fitting my LS fuel rail or my intake manifold.



the shaft on the fuel rail side is wider.......and the injector itself is longer.

any way to make these fit without extensive mods or should i just sell them again?


thanks in advance.

 

is the picture for comparison? or are those supposed to be the same injector?

 

as cheap as injectors are I would just sell them and buy new ones.

 

sorry the black 550s fit in my fuel rail/intake manifold. i was trying to upgrade to 720cc. so yea the pic is for comparison. 550s fit, 720s dont.

 

it looks like your going to need to bore out the fuel rail so the injectors fit. Also for the bottom seals. It looks like you took the stock seals and stretched them to fit the 750's. I would suggest getting the proper seals or boring them out also to fit the injectors properly and it should fit.
