Fuel Reservoir Check Valve Problem in 1988 Model
My 1988 Ranger has the 2 fuel pumps system with the single-use fuel reservoir
(with no filter) between the pumps. The truck had not been starting or running
well and I traced the problem to the fuel reservoir. The reservoir bowl
o-ring leaks and the reservoir inlet check-valve is bad. The valve has
"jumped" its seat and rattles around loose up inside the reservoir top along
with the spring. I can pull it back down but it's too worn to stay in place.
If I blow air into the inlet nipple the valve sometimes blocks the fuel
inlet passage. I think the same thing happens with incoming fuel. That is,
the valve piece blocks the passage and starves the reservoir bowl and frame pump
of fuel and air gets sucked in through the leaky gasket. The engine runs
really crappy that way.
My question is this: How essential is the reservoir check-valve? If I remove
the broken check-valve from the reservoir and operate it like that, will the
fuel system still work if everything else is right? Isn't there another
check-valve in the tank-pump that serves the same purpose as the reservoir
check-valve? Has anyone tried running without the reservoir check-valve? If
so, what were the results?
New reservoirs are hard to find and expensive. The only one I found
online is $131.00 plus $4.99 shipping. Aftermarket units don't seem to be
available. Possibly I can find one in a junk-yard but there are no
junk-yards nearby. I'd like to just pull the check-valve piece and spring out and replace the bowl o-ring and try it like that. I may do it. But I'd like to hear you
guys' opinions and experience on the matter. Some of you must know this
goofy 2 fuel pump system and how it works way better than me.
I believe the part number for the single-use reservoir unit is:
