Best way to do it is take out the banjo feed bolt going into your ppump, and put it on a lathe, and have them lathe and tap it to fit a 1/8npt fitting, and then you can take your fuel pressure reading off there. I wouldn't recommend drilling it...I tried that, but it caught, and tore the crap out of the entire banjo bolt. Luckily, I was able to get another one, and just took it to a shop where they ran it on a lathe for me, and then tapped it too.

Unfortunantly, I don't have pics any more....I've since upgraded to an Airdog 150, and eliminated that issue. As far as I know, its the only way to do it to a stock fuel system.
