hi guys
yes u do have to cut one of the posts out inside the pump housing.
it's hardened steel so the pump needs to be taken apart completely.
if u don't romove the post the cover won't do very much.

Wait a minute. I just removed the NA top and put the LDA top without any problems. I didn't see a post in the way. Everything fit as far as I know. Before I put the LDA top on, I compared the 2 pumps internals and couldn't see any difference.
So what's everyone talking about it not fitting? Or did I miss something here.....

This is an NA pump.... click to make larger.
There is a post jutting into the pump, near the governor shaft, the green arrow is pointing in the general direction.

So are you guys saying the LDA top will mount on the NA pump, but won't function correctly?

I assume that it is possible. Look at those intricate parts inside the pump... gives you a good idea of what the LDA is doing (it basically acts like a dynamic fuel screw, being able to increase/decrease fuel quantity)
In theory, you could set the fuel screw to maximum, but arrange the lda fuel lever to compensate, and stiffen the lda up. (may require some shims on the inside of the pump)
Imagine that. Bleed off pressure from your LDA for light town driving + fuel economy, or let all the pressure go to the LDA and have uber power!
Forgot to add. In my pic I said to shim the lda lever... how about just bend it???

Giles just did one for me today, 1.9 AAZ umwelt TD without the LDA, retrofitted with a 1.6 pump top.
Can't wait. It's currently a slug with sub-par fuel economy.

GILES? I don't know you but I could really do with your help on this matter, Can I actually retro fit the lda from a 1.6 td pump to a newer 1.6 td pump that does not have it fitted?

Well, I have NA pump apart for putting a LDA on and I'm sure the long post needs to be wacked or the LDA would be nearly useless. It appears that for an NA the post is the full throttle stop and when you put an LDA on the little arm stickin' down becomes the stop, thus, you now have a movable stop.
Note the two posts sticking in, the long one needs to go.

Hammer time!
I may do this some day.
Too bad that post isn't threaded in or something.

Can someone post a pic of the two tops side by side?
Hell, why not post the bottom side by side too...
This thread is a really Nice read...Thanks to everyone!
so the final verdict is "Yes we need to remove that stopper"? Or no?

Does anyone have an idea how to remove this without taking the pump apart?

What i did is take a dye grinder and grind the crimp on the outside of the pump. Then take a propane torch and heat up the aluminium around the pin. From the inside take a punch and hit the pin out towards the outside about half way. Then whan the aluminum cools it will seal back tite around the pin. Mine has been like that for about a year with no leaks.
