928sg Posted September 19, 2019 Report Posted September 19, 2019 (edited) I'm looking for fuel pressure sensor recommendations. I'm using a Wendon A2040 pressure regulator (up to 120 PSI) and it has a 1/8th inch -27npt female port on it for a pressure sensor. I'm looking for a recommendation based on accuracy and reliability in regards to failure rates (leaks) but also something that is relatively easy to source. Obviously I'd like it to also be compatible with the Link ECU's. It's a N/A motor. Also needs to be compatible with E85 & normal pump gas. Let the recommendations loose~!

cj Posted September 20, 2019 Report Posted September 20, 2019 have a look on mouser or digikey for honeywell PX2 or PX3 sensors. They come in various fittings including 1/8-27npt and pressure ranges up to 10bar. One of them is brass body and the other stainless but are otherwise very similar. Try to get the ones with Nitrile o-rings in them. Nitrile handles contact with fuel better. The spec sheet for these tells you which letter of the product code identifies the o-ring type. Dont buy the chinese copies of these from aliexpress/ebay/etc. Even if they are accurate on day 1, they very quickly (a few weeks) become bascially random number generators. The genuine ones are reliable howver, and provide good data sheets that are easy to set up in the link calibrations 928sg 1 Quote

434josh Posted September 20, 2019 Report Posted September 20, 2019 I am using an AEM brass body pressure sensor. It is the STD Bosch calibration. I have one on my regulator and one in the injector rail. https://www.summitracing.com/parts/avm-30-2131-100/ Quote

I'm not planning on running much higher, but I don't want to run on the edge of a sensor's capabilities. I looked at this one that is rated at 100 PSI: https://www.summitracing.com/tx/parts/avm-30-2130-100/overview Quote

There are 15-20 cars local to me running the same one. 928sg 1 Quote

928sg Posted September 23, 2019 Author Report Posted September 23, 2019 Sensor came in and is also more compact than I expected it to be. Quote
