I read an article recently which said that the fuel pump is proving to be a failing component on older cars. Did you have a reasonable mileage on the car?
Yes, I am at 56k miles. I should say that I have been running the Autotech internals for about 20k miles without any problem - definitely no or, at least, undetectable fuel smell in the oil during this time. The difference is the rail pressure in the past 2 weeks - it is now consistent and high which it was not before (I had a minor running issue with a previous 'developmental' map I was running which often requested lower than stock rail pressure).
I haven't had confirmation of what has gone wrong but it almost certain that it is the OEM pump seal that has failed rather than the Autotech internals per se. I should also say that I fitted these internals myself - although I was meticulous and have a garage full of the proper gear, I don't claim to be an expert. So, in short, I am in no way finger pointing. However, I think it is important to consider that the design of the Autotech internals
might cause an issue
indirectly if the seal was weak. I found this on JKM's website which probably explains it better than I could here:
