Jack;
Good news=the pump has not been run dry and failed.
Yes, FPR pressure is 28 PSI in each case.
1971 "PRESSURE REGULATOR..The pressure regulator is placed
on a bracket mounted on the cowl.At one end it is connected
to the fuel pump pressure line [after the injectors]and the other
end to the fuel tank......When the pressure exceeds 2 kp/cm2
⎨ psi.] the valve opens and releases excess fuel into the
return line to the tank."
"On the B 20 B and B20 E the vacuum regulator
lowers the firing below the basic setting during
idling and engine braking.Reducing the firing is part of
exaust emission control and prevents the engine from
emitting excessive noxious exhaust gasses at idling
and engine braking." Green Service Manual 1971
Did you read 1800/Yankee Thread?
I recomended 'Double Tap' prime.
Excessive throttle can flood it,but is good to
send trapped air thru.[IMHO]
Re: Vacume canister no,Tank vent line to activated carbon 'filter' canister.
Were you scrupiously clean working on the FI system?
Did you cut the lines with a mini tubing cutter to avoid filings?
Remember the filters are 'out back' and in tank.
Injectors are low voltage, careful here....
The cutting torch is incompatible with the undercoating anyway.
And the sawsall does such a neat job in the right hands...
Look me up, I got a green book for you from the'73 145.
Send your address,I will send it,send postage when it comes.
Welcome to the wonderful world of D-Jet.
