well ok listen when we used the fuel press gauge at honda we attached it to eh fuel filter ok and set it to 23 PSI at idle, and then when i put my gauge on my rail it says like 13 or something i dunno if the gauge is gettiong the wrong reading where its at or cvhecking it off the fulefilter isnt the rigth way to do it

anyone know where is the right place to check it?

by the way, i am using a super fuel pressure regulator with no stock regulator on the rail

 

best place is after the filter. either on the line to the fuel rail or right on the rail. your fuel pressure sounds way low...

 

thats cuz we are not using a stock fpr, we r using a super fmu, so ii should check it at the rail then?
cuz the pressures r different when i check it at the filter it is 23, and at the rail it is 13

 

In my helms it says rail pressure should be ~31-38psi under vacuum. When I installed my gauge with the stock fuel pressure regulator it was ~33psi after the filter. your pressure should be in that range if you have a sohc.
