Cool I have a new aero 340 in the tank now, so this won’t obviously damage anything? By the relay it’s the one under my seat correct? I have a 91Unplug eithe the fuel pump relay or the inertia switch and run the engine until it no longer will run.
Some older pumps have check valves that aren't as efficient so you wait 10-15 mins the pressure might drop to 0.
You still get some leakage, but much less than if you crack a line without relieving pressure a bit
Thanks for the info, had a friend that changed his and I don’t think he depressurized his or maybe he did but it splashed him real good when he disconnected and got gas in his eyes and ears!! Trying to avoid that situation.No power means the pump doesn't run so you just run the engine on residual pressure. Obviously iywont run long, but it does relieve some of the pressure in the lines.
Unsure how well the check vakve is in the pump. With my 190 walbro, pressure is 0psi less than 15 mins later
It looks like at some point you modded the headlamp circuit to run off a relay rather than directly through the switch. That's a worthwhile modification that I would keep. Best bet is to get your hands on an EVTM for your model year and a multimeter and sort out what's what in that harness.

I see now. I'm wrong about the headlight relay thing. Looks like you tried to do what was said in that article. However, the relay you used looks slightly different than the one they did.Hmm ok I just posted an article I found which they did pretty much the same thing. Just not sure where I went wrong. Maybe I’ll find the link and post it.
I have no idea what I even did here. I tried this many years ago at some point based off an article I saw in 5.0 mag which is about the same as the one I posted out of the mm&ff. I’m almost thinking about maybe rewiring it back to stock with the two wire connector for the fog light switch then popping in an add a circuit kinda like this guy did as well as brew2lDoes someone make a female plug for the relay that would clean up the spade mess?
So you think running the add a circuit like in the video may end up overloading? I tried that setup in the other article but for whatever reason it didn’t work, unless some where else down the wiring to the fogs something is messed up.The only downfall I see with that is if the fog lights and the radio are on it could overload the ( intended 15amp circuit running to the fuse box.
The issue with the old wiring is that there was no relay in the circuit. All newer cars have seperate relays for high, low, and fog. The reason for that was the amount of load a bad bulb can put on the switch circuit wiring. I have 04 cobra fog lights but utilize a relay and a factory fog light switch. Works like a charm. The 15amp circuit the fuse buddy is plugged into was never meant to carry 30amps.
Does someone make a female plug for the relay that would clean up the spade mess?
