Sorry I got the numbers from Amazon, I looked at the filters for a 420cc powermore and it listed the filter number for the 382cc as well as 2 others.
I ordered a 751-12690 filter and was comparing it to other filters I have and the Motorcraft FL-400S seems to be a match and its twice as long
I will confirm as soon as I get my engine to 1 hour running time. (I installed a hour meter)
