I took my fuel rails off with injectors and stuff to replace my blown head gasket, and not even worrying about the little caps on the end of the injectors that go into the cylinder head, i lost a couple!!! $hitty thing bout it is i thought i could just go pick some more up at the store but NOPE!!! tried parts store, dealership, and junkyard has no newer mustangs! Where the hell can i get those without buying new injectors?!?! mad these things are really holding me up!
