***** OPEN CALL TO THE GROUP *****

I wanted to again request help from the group for the Returnless PWM
Fuel Pump Controller project.

I am still searching for mass-produced automotive fuel pressure
sensors.  I have found only one ... ONE!  The Ford FRPS (Fuel Rail
Pressure Sensor) series which has been twice revised to due to blown
diaphragm problems:  :(
MOTORCRAFT F8CF-9F972-BH  Old Sensor
MOTORCRAFT 3R3E-9F972-AA  New Sensor?
MOTORCRAFT 3R3Z-9F972-AA  Newest Sensor?

I'd really, REALLY like to find a Nippondenso/Denso part for the job -
one that doesn't have a problematic history.

Anyone interested in helping me find automotive Fuel Pressure
Sensors?  Hopefully someone in the automotive industry has sources for
this info.  I just need part ID's and a car/truck to pull it out of.
Then I can wrap up the PWM Fuel Pump Controller and publish the test
results and design.

Try oil pressure senders.

Vince,

I thought I would make a contribution.  Here's what I've come up with....

GM Part number: 15239857. Used on GM full size utilities starting in MY07 and on GM full sized trucks starting in MY08.  AC Delco PN: 213-3837.  I found the part on Amazon of all places, http://www.amazon.com/ACDelco-213-3837-New-Pressure-Sensor/dp/B001DXC11E  for about $26 shipped.  At that link there is a list of all vehicles that use it.  The dealer list price is about $38.  The sensor is used on GM's returnless fuel system and has a range of 100-700kPa.  The mating connector is a Delphi GT150 with a GM P/N of 19115173.  I believe you can get connectors from Newark, but I could not find it on their web site.  I don't know what the factory pull down resistor value is, but may be able to find out if you need me to.

Hope this helps.
