May need a new switchover valve or maybe the plastic lines to it are leaking or attached to the wrong nipples.

Here is mine and this is the new style; actually upside down from what came stock on my 1981 300SD. I could not get over 30mph when the old one got clogged up and this solved the problem. The top nipple is open to the air so do not plug it up.
