What should be the maximum capability of the stock D-Jet pressure regulator? Mine only goes to 36.
If that's normal, is there another similar-format regulator that can go up to around 45psi? Background: Microsquirt project. Was hoping to use the stock regulator, but now need something that I can easily mount in the same location, if possible. Injectors I'm using are rated at 43.5psi. Discuss! |

Just remembered I still have the paperwork for mine...
No minimum pressure listed, but looks like they should be good for way over 43. Highly suspecting that they have the same pressure range based on this. Original recommendation stands... I would find a way to get the rest of your fuel system up to run them at 43psi (realizing that was your original intention here).  |
