Primary pump failure 200

I recently replaced the primary pump and sender unit on my 1992 245 as the former had failed, or so I thought.

The actual cause turned out to be a break in the black wire somewhere in the sealed part of the feedthrough. The continuity measured fine from connector right up to the feedthrough (stuck a needle through the wire insulation), but inside the tank, right at the solder point, there was no longer continuity.

Normally you see failed pumps, but it doesn't always have to be the case.

Oh, and I probably drove around with just a functioning injector pump doing both jobs without apparent symptoms (other than a slight humming with a near empty fuel tank)... for the better part of 11 years... oops...

Thought I'd share this and was also wondering if this is a common problem, or that I was just unlucky...

Is there a way to assess the health of the old primary pump without destructive "surgery"?
