I noticed that my fuel filter cap is damaged (looks like someone tried to remove it with a large wrench. I plan to replace it and intend to up a fuel pressure monitor on. I noticed that the OEM cap doesn't allow for this and there are a lot of companies that make ones that do. I'm sure some of you are running fuel pressure gauges. What brand have you used and had success with? I've read about some of the bad ones and would prefer the recommendations of the community. I looked at the BPD ones (along with oil cap and oil filler cap, set up to use sensors). Just wondering if anyone is successfully using a less expensive setup.
