Adding Fuel Pressure to EBL
 

Is there some where I can get 5v to use a linear pressure sender?

AEM 30-4401 Fuel Pressure Guage has a 0-5 volt output built in.

You can pick up the +5V reference from the TPS. Although I wouldn't put more then one sensor on that reference supply.

Wouldn't put more than one being the TPS, or one additional being the fuel pressure sender?

Due to the current draw, the ECM can only supply so much power to the reference line.

The Honeywell MLH series with the 5V P/S typically draw 4 ma. Not much at all, so figure we can get away with that. The PX3 series even a little less at 3.5 ma.

Once beyond a single sensor, what we have done is to go to 12V sensors. Lose the ratiometric reading to the ECM supply, but they are still accurate enough.

Thanks RBob!

Do you happen to have any recommendations for 12 volt version? They seem harder to find.

Thanks.

I just added a Honeywell fuel pressure sensor, the one that RBob recommended. I elected to add a fused 5v power supply circuit to allow for adding more sensors down the road. Used this box since I could mount it in the engine compartment.

Seems to be working well about 6 months in now.
