Could be. I have underbody panels which thus far have kept everything clean underneath the car. I'll have to wait for warmer weather to check these though.

I think this is the thread on that:
Newer Model Lift/Fuel Supply Pump Rebuild
Anyone ever replace the valves in the fuel lift pump? - PeachParts Mercedes ShopForum

I'm pretty sure my fuel hoses only clamp on. And yes I have a fuel heater (Ironically I never really noticed the little bugger until today while searching for the source of this leak )

I've thought about rebuilding the lift pump on both my SDL and the Gwagen. Again its something that i'm waiting for warmer weather to work on.
