should Stock Carb Fuel Pump do this?

In my seemingly never-ending quest to rid my wife's bus of fuel odor, I noticed this.
Is this bad? I happen to have another brand new Brosol pump that I can throw on if need be. If so, what all is involved? Is it simply unbolt old and bolt on new? I suppose a pressure check would be in order as well? Thanks for the input.

Ya. They just bolt on with new gaskets. Put a blob of grease up in there where the push rod rides.

Is that gasoline or oil coming out of there?

I'm gonna guess it's oil (or grease gone soft)
It shouldn't be of any concern unless it does smell like gas.
Doesn't look like it's pooling. is it wet? or sticky?
new pump would likely call for a pressure test.

Nobody has mentioned that your fuel pump is working itself apart. That rod should be through the fuel pump with a circlip on both ends. In fact, the oil/gas stain on the pump is in the shape of the circlip that should be there. Once that rod comes out, your Bus stops running and you pray you can find that little rod. Push it back in all the way and secure it now before it leaves you stranded somewhere.

Not this one. There is no circlip on either side and the rod is only the length of the pump housing which would prevent installing a circlip even if you wanted to.

Upon further inspection, the goo appears to be more oil/grease than gas. In the past, I swear it was gassy smelling, but I just went out there two minutes ago to check on the circlip issue and it doesn't seem to smell like gas anymore.
In any case, I think I'll check the pressure of the existing one, swap it out and check it again. I'll look it up, but I seem to recall the pressure Weber carbs like to see is 4 PSI. Can anyone confirm?

Those pumps get packed with grease from underneath. Mine is newly rebuilt and is oozing a bit of grease from the shaft. Nothin to worry about.
