Yes, an experiment is warranted, especially if the OP confirms my suspicions. I expect you to get to it as soon as your family Thanksgiving feast is fully digested and you can lay your hands on the requisite pumps for testing. Perhaps with enough lubrication one of your relatives will volunteer their 240 while they're with you -laugh.

In case some of our American cousins reading this aren't aware, up here in the frozen north Canada celebrates Thanksgiving way back on the second Monday of October, making for a normal 3-day long weekend. It gives rise to an interesting benefit for our local turkey producers in maximizing production. Canada apparently exports some 50 million pounds of turkey annually, most all of it to the U.S. market. How much of that is gizzards, I have no idea. After gearing up to fatten Canadians with turkey for our Thanksgiving, they get to keep the production up as they re-focus on the American Thanksgiving market, adding whatever excess is left over from Canada into the supply line. Then they get to turn around yet again and focus production back on Christmas in Canada, where turkey is far more traditional than in the States, again adding any overproduction intended for the U.S. back into the supply line. There's one more flurry of feathered activity at Easter where they're having increasing success replacing the traditional ham here with cheaper by the pound turkey.

And to finish off my holiday banter, there's Black Friday. There was no Black Friday retail blowout in Canada until only the past five or so years. Our retail blowout has always been Boxing Day, the day after Christmas as a federal stat holiday here unlike yours. It's nice to have a paid day to recover and exchange all your unwanted presents. In more recent years that extended to become Boxing Week sales, where you get to pick up all those now discontinued electronics and winter clothing at below wholesale prices that some fool presumably bought at list price the week prior. Then along came the Internet and Cyber Monday. I certainly remember the first Cyber Monday sale with FCPEuro way back when -I probably still have some of those parts in my stock. Of course, with most of our population close to the 49th parallel, we've always been bombarded with American Black Friday TV ads. It took a suprisingly long time for our retailers to figure out they were missing an opportunity, but it's a big deal now with both e-tailers and retailers. I just got back from a minor flurry of Black Friday madness myself, didn't quite make it to the below half-priced motor oil. The ads for pre-Boxing Day sales are now starting to appear even before Cyber Monday is over. It was getting harder and harder for Canadians to distinguish themselves both culturally and economically from Americans, but as long as you've got a guy like Trump running the show, well, let's just say we're not overly worried about maintaining our identity or our sanity -no offense intended to long time GOP loyalists.

Art, my best to you and yours for the Thanksgiving weekend, and as well to all our brickboard followers. Let us all take a moment to be thankful to Jarrod for his renewed efforts to continue and rebuild our little corner of the Volvo world here -all donations will certainly be greatly appreciated.
