ve pump leaves a puddle

[RDowns]

My pump had an intermittant leak from around the throttle shaft. After killing the dowel pin this morning(which was 3/8" out) I picked up my new tps at the dealer(ouch). and noticed a puddle of fuel. Now the pump leaks very good. I can see a spot behind me when I leave a stoplight. Can I fix this myself without pulling the pump?

Yes, the top of the pump can be R&R'ed without removing the pump and the throttle lever seal fixed. However, if its leaking there are several others that are probably close or possibly leaking that require pump removal. Some times the hard way is the "right" way. Not trying to dictate, just sharing info.



Good luck.

I appreciate any advice that I can get. I want to fix this the right way. Friday I ordered a turbo and injectors, Saturday I installed new rotors,brakes and shocks and did the kdp. Today I planned on adding a trans cooler and new deep pan. Hopefully by the end of June I will have it painted with a new grille and bumpers. I have people tell me all the time that I should buy a new truck and that mine is outdated. I like the classic styling and hopefully it will be one of the sharpest 1st gens out there and I will not have to make a monthly payment. Can anybody recomend a good pump shop in the Tidewater, VA area or tell me how I can get this thing fixed soon. I am leaving on a 1200 mile trip in two weeks.

You could perform this task in the comfort of your own garage. Read up on the pump R&R and replace the pump o rings. Pulling the pump top is no secret and is very simple to do. Read up about the gov spring installation. A seal kit is less than 20. 00. May want to install the updated throttle shaft bushing and drop in a new shaft. Install the 3,200 rpm gov spring while your at it. Yada yada yada

My pump I have on now had the same problem. Scott installed a new throttle shaft and bushing and ... ?? it got er dun. Read through the VE info/gov spring sticky on the top of the 1st gen page, will have instructions on installing a gov spring. You remove the throttle shaft while doing that. So as Scott said, might as well install a new gov spring while your there. Get the seal kit and while your in there, replace any seal, bushing, o-ring that you encounter.

I took the top of the pump off and changed the o ring on the throttle shaft I can see the wear marks in the brass material wear the shaft slides in. I couldn't get the truck to restart. I think I didn't index the throttle shaft right. I noticed my tps did not just pop on it is 90 degrees out. Is there supposed to be resistance when turning in the full power screw. I can break the jam nut free and turn it in and out lightly with a 6mm wrench, isn't the tab that the screw pushes in on spring loaded. I hope I didn't pop anything loose when I put the cover back on. That last allen head bolt rear towards the motor was hard to get to. My pump won't rotate to far down and I didn't want to pry on it.

I have never performed the operation on the truck, and for good reason. It awkward and you can't perform the necessary o ring R&R I can imagine it wqould be difficult to rotate the pump down far enough all the while leaning over the fender to perform some delicate work. I simply don't do it.



The tab inside the pump that the fuel screw pushes on is the tennsioning lever. I doubt it's going anywhere. You should fell resistance against it after the screw is in several turns.



You are correct in assuming the shaft must be indexed correctly. There are small hash marks on the control arm that correspond with the slot in the top of the throttle control shaft. Align the slot with the second mark from the top on the left set of lines and align the same slot with the second mark from the botton on the right side set of marks. This would be looking at the pump from the side (where the KSB valve is located)

Ya... . what Scott said... 10:00/2:00 that's the spot.

You may also find that when you are in the process of assembling the various parts like the spring cups/spring/washers etc. the shaft will slip down a bit and make yer life a misery trying to get the throttle shaft to "index" properly... just spin the big allen cap screw on a couple turns and lift it up while doing the indexing part... works good...
