Has anyone had negative results using Hengst Fuel filters? Approximately a month ago, I changed my filter with one I got from EuroParts. I ordered and rec'd a Hengst which was OEM. Since then, I have been having starting problems where it takes a longer cranking time. The filter that was in the vehicle was a Mercedes filter as it had the star on it. The fuel hose from the tank had a worm gear clamp on it that I replaced with a fuel injection type. I noticed some fuel puddling on top of the Hengst filter so I removed the hoses and cut them back slightly and replaced the clamps again. When I changed the filter, I used new o rings for the water sensor. Today I did the new clamps and cleaned and absorbed the fuel. I am still getting a longer than normal crank time. This vehicle used to start with just a hit of the key. I ran the engine today, shut it off, and restarted in 15 seconds. It started right up. So I am wondering if the fuel filter is the problem and if I need to get a filter from Mercedes. I may have some seepage at the water sensor; will know tomorrow for sure.
