550's into 93 NA Rails

Post by camped69 » Wed May 24, 2017 8:16 pm

I'm sure this has been covered but I cannot find it anywhere.
Can someone confirm how many injector o-rings go on the actual injector in this application. I am showing 2, one at the top and one at the pintle.
Thanks!

thats correct just the two o rings. You have to switch out the little rubber pieces in the injector caps as well if I remember correctly

Are you just wanting to replace the O-rings or are you wanting to change O-rings to make them fit the rails?

You should be able to use the USDM 550 side feed injectors as a direct drop in to the 92-94 non-turbo rails.

Hi Josh. I just wanted confirmation on the number of O-rings needed for the install to work. Injectors came with 2 new O-rings.
