fuel in the diaphram area

[randyswelding]

howdy again is havin fuel come out of that vent tube at the back of the top cover ok.i did notice that i was startin to have fuel in with the afc,i never did before or at least i didnt have enough beer to remember

[gear jammer 91"]

As far as I know there is not supposed to be fuel in the afc. I believe I have heard of people sealling the pump top up so that fuel cannot come out when this happens, but it's not the right way to go about it. I'm not sure what seal has to go bad in side the pump to cause this, it might be an easy fix or it might not.

[PToombs]

It's only an o-ring that seals the pin. I think the top has to come off to replace it, but I can't remember exactly.

The top has to come off. We are doing one on Case500D's truck. Buy a seal kit before you start the repairs.

ok so then ill get that when i do my govener spring.so its just a oring seal that sounds easy enough

[aspoonhour]

It's sort of a pain to get to but I did it on my wife's 1990 CTD Ramcharger. Definately, do it while you are putting the gov spring in. The top is already off. I couldn't explain how to do it, but could probably DO it again. I do remember that you need to remove a lever that is in the way and in order to do that, you need to pop out some little ball bearing seals. That was the only part that worried me. Worked out o.k. Just take your time.



I wish I still had this VE pump. I'd take it a part and get pics for you. Sorry.

His pump might not have the ball bearing type of seals. It might look like a freeze plug. The ones we took out of Case500D's truck did.

okydoky i got the gasket kit and my spring came in taday and i cant get it in until the weekend i got ta use the truck to finish another side job but ill look for this plug thingy and fix that too.since im there how do i remove the afc lever,would that be a good idea since i way in at 10250lbs and tow trailers?

Removing the afc lever would not be a good idea if you plan on towing with your truck, your egt's would climb very fast and get very high. If you want to get an idea what it would be like take a long bolt that is the same diameter and thread pitch as the smoke screw and put in were the smoke screw goes, and run it all the way down. This will have a similar affect as removing your afc lever, but it won't give quite as much power or fuel.

[randyswelding]

ok so im thinkin the afc lever stays in for right now,or until i get another truck for play

[randyswelding]

yap mine has the lil balls(the pump needs to listen to some AC/DC big balls song i think it may help )i got a bosch seal kit but i need to get em out to see it i got the seals or not

[dpuckett]

If you are getting fuel into your AFC well (and, consequently, have fuel coming out the vent tube), you are looking at the wrong part of the pump. The o-ring that seals the AFC guide pin is behind the throttle lever (remove the throttle lever, but leave the shaft), behind the hex key plug. Remove the plug, then carefully remove the pin. You will need a small pick to R&R the o-ring. Get the o-ring back in, and then installation is reverse of removal. This one can be done with the top on the pump- BTDT.
