1999 E320 fuel tank issue
To add fuel, I have to add very slowly to keep from shutting off. After a few gallons, fuel leaks out under the car near the right rer wheel.

To be helpful there is a "charrcoal cannister" and "shutoff valve" as part of the tank system - think of it as a fuel-fume-recovery system.
If someone has been "overfilling-the-tank" - meaning putting more gas in after the gas pump shuts off - that canister can fill up with fuel - or there can be problems with the shutoff valve itself - or corrosion in the electrical connection going to that valve - or brittle/broken hose connections - etc - usually detected visually or with a "smoke test" (not as scary as it sounds
A older post can give you better visual insight to what these components are..

A used/returnable charcoal canister can be found on eBay - same with "used" lines - or "used "valve".
Good luck !

You have been helpful. Thanks, I have exposed the charcoal canister and valve as well as the tank and filler line. Nothing obvious wrong; no leaking hoses or collapsed tank ( heard that can happen if vent occludred )
