[V8] Fuel injector problem

[ron_01056 at yahoo.com]

I'm going to disagree with u about not needing the adjustable fuel pressure regulator.
Anyway I need it with the bigger fuel rails I have.

I've got a bunch of spares if you need.  If the pintle cap is missing, its a
small plastic cap that goes over the tip of the injector, you're going to
have air/leak issues or spray issues, or both.  Its somewhat important.  Had
one of those fall into the engine on the mazda and it ran like dogshit until
fixed.   More prominent since there are only 4 cyls instead of 8.

For the record, Ford Racing 19# injectors with plastic bodies and a Porsche
944 S2 regulator at 3.8bar work great on a 3.6l.   Don't need the regulator
on a 4.2l car.  The ford injectors are a newer, smoother design that is
superior to the older injectors.   Also, they are awesome blaze orange which
equals  +10hp.
