928sg reacted to Adamw in R8 Coil wiring
For the main power/ground I have used 18AWG tefzel, but as I said above Im only running them at 8A peak. If you are a high boost turbo you may want to go to 16AWG.
If using Tefzel wire, 18AWG is good for about 9A, 16AWG about 12A. Low temp PVC insulated wire would need to be bigger.

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
