It isn't just one pump, and it isn't obviously corrosion causing it. I've seen several HP pumps fail due to holes including ones that spent their entire life inside the fuel tank. (I'm not talking about modified, just regular ordinary repair jobs)
End of the day though, it's your car - I just said I wouldn't do it.

I suspect it's more of a manufacturing defect - you have to remember that as a garage mechanic I get to see lots of failed components (because that's why it is here...) and I like finding out why something has failed in service. I have found more than one fuel pump (in tank) with a blow out through the case leading to enough pressure loss to stop the engine, and I've seen enough failed external pumps to not want one inside the car. I accept that the pumps were not brand new, but nothing stays new, does it?
Besides, even if it is one in a million it does happen and happened to someone on this board - a freshly converted (with all the proper bits) mk5 cortina 24v caught fire outside his house, and destroyed the car in under 5 minutes. Thankfully no-one was hurt, but it's a tough lesson to learn about fuel safety.

Had it as well, external ones with bodys that have coroded from the outside in and in tanks ones that have simply worn through the body, my theory was worn bearings alowing the impellers to wear through the outer case as in one case it was a slit not a pin hole others were pins holes which TBH we never pinned down but assumed as mr scarey that a manufacturing problem (air bubble? ) had caused it even though one of the cars was well in the 250,000 plus region of life ??
Usually the seal just gives up at the crimps and pisses fuel every where, had a brand new one like it on a jag not 3 months ago, fitted it up and it curse word petrol all over the place from the crimped seal, mind you it is a rarety, usually they just refuse to turn but i do tend to get lower end customrs with knackerd cars kept on the road on a shoe string.
