fuel pressure measurement with EFI

PostPost by: bob_rich » Sun Dec 04, 2011 12:49 pm

Hi Folks

Fitting an EFI to the twink. Just a simple question ( I hope) can I read the fuel pressure at the blanked off port on the fuel pressure regulator?? I assume the pressure should be read on the output side of the fuel rail
the attached note explains the question fully

thanks in advance 4 help

Bob, 23 downloads and no answer so far.

Answer is yes! Both inlet ports see the same pressure

From your picture both ports with arrows will be a straight line connection - so the blanked port can be used for a pressure gauge. FWIW, this confirms Gerry's reply.
