While trying diagnose an odd loss/lack of power at high end that seems to "surge", I noticed that there are bubbles entering my clear fuel filter that's about 6" after the fuel pump. My thought is that somehow bubbles are getting introduced at the fuel pump.

Now, the fuel pump isn't one I've seen before, having multiple aluminum castings, saying "made in canada" around the outer rim, which is screwed together with multiple screws and having a top that is also screwed on. Most likely yet another hack from my caring, but odd previous owner.

So...the question is, bubbles coming through the fuel line, entering the filter, then traveling to the SUs would certainly be a cause for worry?

Meanwhile, a new pump is on the way, just in case that is wrong.
