Can’t remember is exact, most issues I saw were cam related or physical damage. Solid as their cars and bikes.

Schrader should be be on the fuel rail by the injectors on the intake befor the return regulator. Think it’s 15 psi maybe 30. Don’t remember if it’s the car or bike based for that year.

You need a special fitting to check fuel pressure, no schrader on that motor. There is a filter on the VST behind three screws, a triangular cover. Will cause fuel starvation if clogged. Also a filter on the high pressure pump in the VST. Try the return filter first. Easy to check. Fuel pressure is around 35 psi.

Make sure you also replace the return filter behind the three screws.
