Just replaced it. Chasing a stumble while running. Or is my in tank pump not feeding this one enough fuel?

Yes, the tank pump was the one you should have changed.

I've got one of those too! That'll be a job for tomorrow.

The main pump should be virtually silent when the tank pump is operating properly.

Thanks for the replies. I have both pumps and figured it was most likely the in-tank pump, but the main pump was the least hassle to change first. I'll get the in-tank pump done tomorrow. It'll be nice to have the wagon back on the road!
