Standard pump with high pressure spring.
Who needs a stinking test , I have proven tests over the course of 45 years.
not one flat cam or one toasted bearing.
Granted my tests only accounts for an rpm range of 6500-6800.
I work on stuff where you can only get a STD pump. That can be a challenge.
The modified Ferrari 308 QV twin turbo engine that I have in the shop at the moment, has some oiling issues:rolleyes:
