Mechanical fuel pump identification

Does anyone know what length pushrod is associated with this pump? I haven’t been able to find much information by searching the part number. 

 

It came with this rod, which I’m assuming is incorrect given the length.

Need to see the part that the rod rides on inside the pump.

Two types of fuel pumps for M10 2002s.  The early style  (left) and the later stamped steel style (right).  It looks like you have the later style (the early styles are NLA).  The later style requires a slightly shorter pushrod (roughly 3 and 1/4 - 1/2 inches). 

 

Note the receiving surface on the pumps and you can see why.   I prefer the earlier styles which I currently have in my 69 2002 but over time the pushrod wears down the receiving surface on the pump.   I keep the newer style as back up in a bag with the shorter rod.

They can be rebuilt using a rebuild kit for an air cooled, carbureted VW Beetle.

The replacement pumps from Italy have a habit of the pad wearing through, gradually lessening the stroke until the pump won't.  The OEM German pumps didn't do that.  I was able to dismantle my worn Italian pump, MIG weld up the pad and grind the surface flat.  Kept it as a spare.

Thank you! All very helpful. Do all the pumps flow the same amount or were there flow differences between the TI and base 2002s given the different carb setups? 

 

 

Here's the base of mine for future reference. Part 72087651

FYI, not sure about the NLA pump.  This one was purchased off Amazilla a couple months ago. Made in Italy. Replaced screws for easier tightening of gasket.

Both the 2002 and the ti share the same pump according to real oem.
