Dr. Bert. You can imagine my concern when some individuals where stretching their springs to 26-27 mm.

Some of those relief valve springs were only meant to be at about 21.5 mm originally. I could not even estimate the base pressure they were running if their lift pumps were really still good.

Needless to say these individuals decided not to use gauges. I had no desire to see possible damages occur. Especially with so many unknowns. Yet where some of them landed up was quite interesting. It did open a possible future window at some point yet to come.

Of course it was not from a known pounds per sqare inch perspective. Some might have been above twenty five pounds in my opinion.
