Fuel Injectors

I Was Wondering If I Could Put 4 Fuel Injectors In Now And Then Two More In Later. Cause I Recieved Four In The Mail But The Other Two Haven't Arrived Yet. Just Wondering? Thank You In Advance.

you should be ok...i replaced the 1st injector and the others are the originals. its been perfect for about 10 months now.

Thank You, Thats What I Thought
But I Just Wanted To Be Sure.

Are the "new" ones different from the originals?

If you expect the others soon, I'd hold off and do the job once instead of twice. There are small o rings on the fuel feed line and return line. They may need replacing once you remove the injector manifold. Be careful, they may remain in the manifold or regulator. There are small spacers in there too.

I bought a set of Ford #19 injectors on ebay and installed them on my '88. Everything went smoothly until I started the engine. Fuel began spraying out from the fuel feed line because I nicked the o ring when I reconnected the line.
