I think, but not sure, that the fuel pump in my '99 SLK230 and '01 SLK32 are interchangeable.
I'm selling my 230
I just bought a Code3 for my SLK32 - not installed yet - maybe a month or so. So I'm thinking more fuel may be helpful. 32Crazy upgraded to an SL55 pump PNa0014704994.

I have to replace the pump in my 230 (before sale), so I was thinking should I buy an SL55 pump and put it on the SLK32 and then put the SLK32 pump on the 230.

Although...SL55 pumps maybe a lot more expensive....that's the price you pay eh..

Can anyone confirm my thinking?
