Moin! It’s about my Blazer k5 Bj1982 with 350 engine. I want to mount additional inserts and I’m interested in how you did it. In any case for the oil pressure. Oil pumping is perhaps not wrong and voltmeters can’t hurt either. Which instruments are good from your point of view? You can get rid of real money, but there’s also a set of 3 instruments for 30 to 50€. Do you know them? Are they also good? And how/where did you have the built-in / connected? ask: 1. Which instruments are a must? 2. Do you have experience with the favorable instruments? 3. Mechanical or electric? 4. How/Where are the feelers best installed? Would I be happy if you had some helpful tips for me.
