I am guessing but stock fuel pressure should be around 38-39 line off. Jerryl or Boost231 will confirm this. If no response send either one a PM. Thanks- Brad

At idle with the stock regulator I recall mine around 34 them when you put the vac line on it dropped to 28 psi.
At WOT you should not have any vacuum there because the engine is under boost.

As stated by others:
Your FP with a stock regulator should be in the 37-43 lb range, line off, according to GNTTYPE.
Expect to see 37-39 PSI range (typical). :biggrin:

At WOT, (when you get into boost), the FP should be "static+ boost".
So if static FP is 40, and you run 10PSI boost, you should see:
40 + 10=50 PSI

Here is a good page for reference for the future as well.
Hope this helps.
