Fuel Rail Schrader Valve Q&A Period

Hi, Gang,
While proceeding with fuel pressure testing, I removed the cap from the Schrader valve at the end of the fuel rail.
Fuel flowed out quite readily. Does anyone know part number? Is this the same size as the others in the fuel lines?
Thank you.
Bill

Are you asking about the cap or the "valve core".
I think the valve core is the same as a tire valve core (please verify).

Please let us know what pressure you see when you test. My 2006 S60 2.5T starts at 55 PSI but drops to 43 after about 30 seconds, measured on Torque and with an autopart store loaner fuel pressure gauge. Wondering what others see.

there is both a pressure spec and a drop spec after 30 minutes - I think your pressure is ok, but you are failing the drop test.
