Get a pierburg if you can for the water pump. They’re more OEM than Mehle is for water pumps even though both are OE manufacturers.
Pros: more OEM

Pierberg all aluminium has been good in mine.

Vehicle:

I replaced mine with a pierburg one. after install it was fine till I hit a decent bump, which led to overheating limp mode (i stopped the car as soon as this happened).
Pros: fine after install
Cons: overheating limp mode
The carburetor leaks some fuel into the intake, I'm assuming something is leaking or adjusted wrong and it floods the engine. If it's been sitting for a week or longer it starts instantly, also starts very well soon after driving while it's still warm.
Pros: starts well when warm
Cons: leaks fuel into intake
Vehicle:
Mercedes
I kind'a have some project and I need to use Pierburg CWA50, all I got in my country is this pump from benz (**A0005001986**), is it same model as Pierburg CWA50? Because the head pump is same but the connector is different (facing upwards). I tried to find specs from this model, the result is empty, can't find any clue about flow rate. I do have original code from Pierburg, which is **7.04933.56.0**, but can't find flow rate either.
Part number: A0005001986
when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.
Cons: short lifespan, immediate failure
Mileage: 32187 km
I've had 2 of these die in less than 1 year. Junk!
Cons: died in less than year
Honestly, personally I wouldn't get a Pierburg. Got one, the all aluminum one and it failed right away, first day of driving. It was hard to push in the plug as well. And they are made in China these days, cheaply made it seems.
Cons: failed immediately, difficult plug, cheaply made
