Hi B767capt, I followed your guide to install fuel pressure gauge 6 months ago. I tested the pressure dropped from 83 to 0 psi just within 2 hrs and I suspect some leak. So I changed all the injectors 2 weeks ago and tested again but I can't get 80 psi stay for 12+ hours. My fuel filter also changed before this new injectors. Will other part/location suspect leak other than these injectors? Any thoughts? Here's my pressure psi reading:
off - 83
1 hr - 43
2 hrs - 21
3 hrs - 13
4 hrs - 8
5 hrs - 5
5.5 hrs - 4
6 hrs - 2
6.25 hrs - 0 psi
Thanks in advance.
