D-Jet Fuel Pressure Regulator, How high should it go? Options

[GregAmy]

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!

Thank you sir!We're already overdue for a beer visit. I may pass by tomorrow if you're in.

Here's some docs I found when I was going through paperwork. The injectors should be OK at higher pressures. Just not clear where I *should* run them. I clearly do not need the flow rate at higher pressure, but I wonder if reducing the duty cycle improved efficiency. I wonder if I'll even notice a difference at all by bothering to go over 35psi.

I would run them at 43 If possible as that is the lowest pressure you have all the datapoints for. Increasing the pressure may improve the atomization but if your pulsewidths get to small mixture control at idle can become a problem.

But... if those injectors can make a decent spray pattern at 35psi I doubt you would notice much if any difference by going to 43, the only question is how well do they fire at 35?
