I did my fuel filters today on my 350SD. Far from the first time. Fuel was on the light, so very low.
As soon as I released the main bolt, it started seeping out. But it never stopped. And to make it worse, somehow it was next to impossible to coax the filter out.
I don’t know how much came out, a gallon? A pint?
And since the install was equally hard, I had to tilt the filter on its side, spilling a lot of diesel purge that I used to prefill the filter.
What’s the issue? This car is new to me. I don’t recall having this issue on any other 616/617/602/603 that I own. The most recent were a 602 and the 603 in my w140. Neither made any mess at all.
I do think proper practice is to have a loop in the rubber hose going to/from the prefilter. This w126 doesn’t have that.
What gives?
Maybe I have too much pressure in my fuel tank??
