Setting Fuel Pressure question...
K so I was driving my car around today and getting all the annoying **** worked out on it. I got everything taken care of minus re-setting the fuel pressure.
Before with my T25 I had set the fuel pressure with the vacuum on to 44psi (stock fuel pump). That worked out perfect and made it so that I only needed to take out just a bit of fuel on the SAFC for fine tuning. Now onto the Walbro...I have it set at 44psi with the vacuum on and my car runs stupid rich unless i take out a crazy ammount of fuel. Im not liking that since the more extreme you adjust the SAFC the more it plays with your timing which I dont want. My question is:
Are we supposed to set the fuel pressure with the vacuum ON to 44psi or are we suppoed to take the vacuum off and set it? I noticed that when I took teh vauum hose off and capped it the Fuel pressure went up. Anyway let me know for sure. Thanks
