Return lines are a wear item, they don't last forever. I had to replace them on my cars before ULSD came out and I haven't seen any rise in the incidence of them needing to be replaced since.
I think the change to ULSD was much ado about nothing, I didn't notice any change in how my car ran or anything else after the change. Pretty much the same with ethanol, that one is something I'd rather be without but I don't see it as big a problem as some people do. When we first switched I had a little trouble on the snowmobiles but once I quit using Sta-bil and switched to Seafoam for my gas additive the problems I'd been having went away entirely. The only time I have trouble now is if I forget to add Seafoam so I add it to every gallon of gas I buy at the time of purchase. -Curt Date: Wed, 16 Apr 2014 12:51:47 +0000 (UTC) From: roger...@comcast.net To: mercedes@okiebenz.com Subject: [MBZ] ULSD Message-ID: <1038933319.27592994.1397652707103.javamail.r...@comcast.net> Content-Type: text/plain; charset=utf-8 Max, It may also be that you have a newer car and replaced all the o-rings. Since the ULSD came out, I've replaced the fuel return lines on both of my old 617s. Nothing else was a problem, but the return lines just started to seep fuel. Once replaced with newer lines/material, they have been fine since. I periodically add some diesel treatment to my cars which helps remove moisture, clean the injectors, lube the pump. Now I know the oil lubes the pump also, but not internally where the fuel flows. Anyway, maybe ULSD is good and maybe it's just another marketing/take care of my business buddies ploy similar to adding ethanol to gasoline. Just my view anyway, your mileage may differ (and it will if you use gasoline with ethanol). Best Wishes, Roger Roger Hale Dinnerware Classics, Inc.
