This weekend I am changing the fuel filters on my 606 engine and was considering filling the spin on with pure DP or a mix. Any comments? Anybody do this? What was the result? I want to avoid cleaning ahead of the filters. Will the engine run on 100% DP in the filter? I figure a fuel filters' worth of fuel is good for 1-2 minutes. From what I have read on this forum, DP works pretty fast on the injectors.
