I bought a new spider assembly recently and it comes with new brackets and fuel pressure regulator, but the new pressure regulator is different from the original I had on it. The old one has a valve tip or something where the vacuum hose goes on it I believe, and the new one just has a hole in the center with no place to put a vacuum hose....when I bought it, it said it was meant for my vehicle unless they just put on the wrong fuel pressure regulator.... Does anyone know what this pressure regulator really goes to? And if it matters or not by not having that valve tip at the end?

 

its dosen't matter,they might use it for external applications,this was the first one that i have seen inside an intake manifold,don't know what chevy was thinking

 

I just wanted to make sure before putting it in, and it spilling gas everywhere or something lol

New Fuel Pressure Regulator
(Notice this doesn't have that stem on the side..)

 

It is fine, go ahead and install it. That is part of the new updated spider assembly. There is no vac line to put on it anyway since it is inside the intake manifold
