I edited this.....you answered my question before I could get back.
Confusing!?
A kinked hose...Why didn't you just say that right in the first posting?
I think I fingered this whole thing out by examining my ruined and fully
opened up TB Top Half
and the Chilton Manual diagram on page
4-30.
The Fuel goes from the Fuel Pump thru the Fuel Filter into the TB and
directly to the Fuel Injector. That means "A" is the input port.
YES?
It then passes thru or past the Injector (some gets injected into the TB)
and goes to the bottom half of the FPR and into the chamber and
if the pressure is high enough - lifts the diaphragm and then
can go down the little hole and back to the tank thru Port B.
That big rectangular hole on one side of the FPR chamber bottom half
is just a "pit" for some reason...(?)
What is the purpose of the top half of the FPR - that portion is connected
directly to the intake manifold - a partial vacuum!?
As Mr. Spock (on Star Trek) - my hero - would say..."
Fascinating!
