ac fuel pump repair

hallo

i hope , i ll be clear enought .



on my cj 1968 , i ve a ac fuel pump with vacuum pump for my wipers .

the fuel diaphragram was leaking . so i ve bought a complete kit .

when i ve openned the pump i ve changed everything from the kit except 2 valves .

why = because there was no valves but a kind of brass socket ( red circles ). they are on the " wipers pump side "






on this drawing , we can see those non changed valves . on the yellow circles , we have those valves





nb: i ve changed those with the green circles (valve picture before changing of the wiper sider of the ac pump)








MY TROUBLE :



the fuel pump is ok , engine runnig fine . my hose for my wipers are brand new and new clamps

but my wipers don t move . i ve tried to move the thoses from a nipple to another :same thing no movement .

the depression coming from the intake manifold is perfect .

when i m pumping with my mouth on the hose going to the wipers , i can see them moving when i pull the sink .

when the engine is running and the depression hoses is on a nipple or the other one : no depression a the other nipple

as far i remember my wipers work , very very slowly . and (i m sure of this) , i can hear a depression noise

some one can help me , please



have a nice day

 

with an old pictures




yes : the hose from the intake manifold big sucking

but for the other nipple (when i hookep up like my picture ) = nothing

 

i ve called one of my friend , is sure and remind me that : 2 years we made an offroad trip under the rain and they were working . very slowly but they re working . sometime he had to help with the manual sink



ok , i can try to put valves but the side is ...



if i m oversizing the " old picture " (sorry i don t know the rieght word in english) , they seem to be in the same side , but not sure .

 

i ve changed the valve that i can see .

but at the end i had 2 valves remaing of my desk .


for these 2 valves : the location is filled wilth the brass plugs

 

X2. It seem someone blanked off the vacuum side of the pump.

If the wipers worked at all, it was on the engine vacum form the manifold.

 

i ve cleaned and greased my wiper .

i m agree with all of you, the brass plugs seem stranges .

like my diaphragms were very old , perhaps i had leaks and like that the wiper work

 

what is the rythm of that kind of wiper ?

 

that s correct

the problem is located on the body .

valve or no valve ????

and if valve :what is the right side ?????





never show you my jeep (2 years ago , offroad trip for the d day)

 

exactly

 

i m far of that , very very very far !!!!!

for a complet cylce , the wiper needed for than 6 or 7 seconds
