But will go back to 60 psi temporarily if you step on the gas. Is that normal? Yes
Is this the CPI Vortec -the regulator is under the intake manifold tuning valve-
The Spider is the little CPI injector with 6 little injector lines and poppets at the end of those lines. Looks like a spider if you imagine hard enough.
There are 2 larger lines that connect to it also, they're the fuel supply and fuel return to the fuel tank lines.
If you take the top off the manifold, you'll find a puddle of gasoline. A puddle on the driver side is cracked fuel supply & return lines. The CPI is OK, buy a nut kit(which is what they call the fuel lines?)!
A puddle on the passenger side means the CPI regulator is bad but another regulator is available.
