Series 1 oil pressure

[Bucky]

The series 1 107 been sitting a long time and l am trying to varyfy the oil pressure  reading the most accurate is from the the rear of the valve cover where the oil pipe connects.  I can buy a 3/8 BSF M/F tee for the gauge which can do the job from England for  4 pounds. Shipping is 25 pounds lol   Anyone out there that can help .?

I'm not sure exactly what you need, but you might be able to buy locally.

Try going to a British motor cycle repair shop.  They use BSF fittings.   Bert at the Sports Car Center may be able to help too.  780 440 9426
