Hello everyone. I have a 1988 190D that is leaking fuel due to a constant pressure in the fuel system. I replaced the hose and double clamped it, but it is still leaking around it. If I take the fuel cap off after it is turned off then it releases a lot of pressure, but will still leak. I Drilled a small hole in my fuel cap but it is still doing it. If I simply leave my fuel cap loose then it shoots fuel out around it. Can someone please help! BTW I usually run it on WVO but it is doing it even with regular Diesel.
