Quest for originality- Pierburg fuel pump?

[eriknetherlands]

My car has (had 7 years ago) a functional fuel pump. Now disassembling my engine bay for new shock towers, I want to shine and bright all as I pick stuff off the car.

My Pierburg fuel pump looks corroded: it's not too bad, but it simply isn't up to my standard. So I would like to re-zinc it, or replace it.

To re-zinc it I'd have to open up the crimped steel pump house from the aluminium pedestal, seperate the outer housing, get it zinced and crimp it back on.

Now here's my question :
- what happens if you open it up? Does it have a big spring or a 1000 components inside that I never get back in?

Other option is to buy a new one, but Walloth only carries a version that looks post e9 era. It even has a QR code on it. Would be ok only if no other (really no other) option....

Have you tried WD40 and steel wool?

 

[HB Chris]

I think both are period correct.

 

[bavbob]

yes wd40 and 0000steel wool. Follow with 2k clear coat.

 

[HB Chris]

I won’t use steel wool anywhere near my car, I use bronze wool as the fibers don’t rust.

OK, gave it a try. I had to sand it to get the rust spots out. Painted 2K clear over it, downside is that now it's iron colored, not yellow CAD / zinc...
Will do fine, but i'm still on the lookout for NOS / look for a donor with correct yellow passivation layer still intact.

i knew i had one somewhere..... from converting to electric pump.
Seems slightly different , filter top can't be removed.
And there is ( was) grey paint on it.... was this painted oem ?

Chris, I just take a magnet and go over the area to grab all the fibers.

Was originally yellow zinc. It was probably rusty like mine at some point.

I was tempted to tell you to expect Marilyn Monroe popping out from the pump singing "Happy Birthday Mr. Erik" so you would open it...
I recall @deQuincey had sources for NOS (pumps, not Marilyns).

Have you tried Scotchbrite pads? 3 different grades

I use those for scuffing metal before paint but that’s a great idea

Or I will sell you a new Pierburg that I got from @deQuincey. NIB.
And I assume the correct one for the E9. Also comes with 2 gaskets for mount.
The hand written note is from @deQuincey.
I now have a FI system and no longer need this part

@Keshav has connected me to a part that is already on this side of the ocean, so, @steve in reno , thanks for your very kind offer, but it won't be necessary.

Thanks for all your insights.
