Fuel Pressure Regulators and setting meters? - Toyota Yaris Forums

Nagoya_TRD. · 05-12-2009, 04:42 PM

I just trying to learn a little more about fuel systems, but i have an idea what the regulator does. What is the point of the "setting meter" other than showing the fuel pressure?

In this case, let's talk about SARD Fuel pressure regulators and their "setting" guage.

Someone explain this part of fuel systems to me. Thank you.

The gauge shows the pressure visually so you can make adjustments quickly, without having to read it from management software, etc.

Will this work only for the Sard FPR or others as well?

Nexus1155 · 05-14-2009, 02:10 PM

im assuming its universal and you can tap it in anywhere....

A gauge is a gauge, as long as the fittings work. We ended up putting my gauge at the end of the fuel rail - no need for a line or a bracket that way.

The gauge shown appears to be the one used to set the fuel pressure on the dyno while tuning and not one you'd have installed constantly (or be able to view constantly since it's in the engine bay).

a standard (electronic) gauge has a sensor attached to a sending unit which then sends the data into the gauge in the cabin.

so yes there is a difference between a standard electronic fuel pressure gauge and the "setting" fuel pressure gauge.

I have a regulator (which sets the pressure) and a liquid-filled gauge off the fuel rail, in the engine bay. I'm assuming it's a mechanical gauge.

yeah the gauge in the first post and link is the same idea as the one on your fuel rail.

simply for setting the fuel pressure, not for monitoring fuel pressure.

well, if you sat on the valve cover and leaned way over, mayyyybeeeee you could watch it

wait, you can't see yours even when the hood is up without sitting on the valve cover?

what's the point if you can't see it?

Here's my set up:

LtNoogie · 05-15-2009, 12:42 AM

Garm, what pressure are you setting your system to at idle? Is your regulator boost compensating?

cali yaris · 05-15-2009, 09:33 AM

No, it's a fixed pressure. It's the injectors job to squirt the correct amount of fuel. We have it at 40 right now, but if the injectors max out we may end up with a higher pressure. Not done tuning yet!
