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!

Hi Norbert, thank you for the Bosch list its very helpful. I can see that that my chart above needs updating, I did not have that Bosch list available back then. I had used other web sources listed in the references, many were injector rebuilder shops.

I developed my chart maybe 15 years(?) ago, based on the references available at the time, which are indicated on the chart. It took quit a bit of time as I recall. Looking those up now, I see many of those sites have gone away. A couple are interesting though. The Weiss chart was a reference for me back then, but it currently lists the 0 280 150 019 injector at 320.6 cc/min, and the Witchunter chart lists it as 406 cc/min at 3 BAR. I wonder why they changed it?

One would think rebuilders would use accurate info.

I did not see an indication of what the test pressure was for the Bosch chart values. Do you know?
