Title: Mercedes W202 saddle tank sump solution?
Post by: DWRDeep on May 23, 2025, 09:49:02 PM

Hello all, I haven't found where to introduce myself here & I hope this is the right place to ask this question.
I have used waste veg oil in my cars for many years, filtered at various times via socks or water filters down to 1 micron.
Currently I'm running a lovely 98 Merc C250 TD Sport, & have been advised never to let it go below ½ tank full. It runs beautifully.  I know from whispers that people known as Spock & Chissel(sp?) successfully connected the tank halves with a sump modification, but I haven't found details.
I'm thinking of drilling a hole near the base of the upright tube in each sender unit, inserting tubes to hold the drain valves open, and connecting with a T so that both run to the main fuel feed.
Comments please?

Cheers, Phil

Thanks -sadly, many forums seem to be this way now, probably as people gravitate more & more to social media - I fear that a lot of information is to be lost in this way, I'm not sure ...

Unfortunately Spock and Chissel didn't migrate across from the VOD. The information you require is locked in that forums archive that cant be accessed now. Shame.
