fiatslug87 Posted July 28, 2011 Share Posted July 28, 2011 I bought a set of injectors from precisionautoinjectors.com and they have blue plastic tips. Are they protective caps that require removal or do I just install as is? I've tried contacting them but they don't reply. Link to comment Share on other sites More sharing options...
jimoshel Posted July 28, 2011 Share Posted July 28, 2011 I think they should be removed. Otherwise how can they squirt gas? Link to comment Share on other sites More sharing options...
fiatslug87 Posted July 28, 2011 Author Share Posted July 28, 2011 The ports are visible (hard to see in the pic) the blue "cap" does not cover them. Link to comment Share on other sites More sharing options...

ratrapp Posted July 28, 2011 Share Posted July 28, 2011 they are called pintle caps.used to you could buy replacement ones(maybe you still can)if they became hard and brittle and cracked or crumbled when removed.they do need to be on there.
