Boyd Tank Installation

I think another solution would be to replace the pump with one that does not have a connector installed on the wires inside the tank, assuming Aeromotive does a good job of sealing the ends of the wires down inside the pump.

I had a vendor tell me the same thing about 15 years ago with a differential. I went ahead and modified it and fixed the problem. Customer is still running it to this day. Vendor had other complaints and fixed their problem by doing the same thing I did....go figure.

I added a time delay relay to my fuel pump wiring to run it for a few seconds when the key is turned to the run position. This will help to prime the carb bowls. I have noticed that the engine takes a bit longer to start if my truck has been sitting for a few weeks. I'm assuming this is from the fuel evaporating out of the carb.

I made some modifications to the way the time delay relay is wired. This eliminated the need for a diode. I had a diode in there because I installed a mini starter a few months ago that doesn't have an Ignition terminal on the solenoid so I had to attach the yellow wire to the Start terminal along with the purple wire. Without a diode, the 12V from the time delay relay would have back-fed to the starter, which would have activated the solenoid. Now the fuel pump relay activation signal passes through the Normally Open circuit of the time delay relay after the time delay relay finishes priming the pump and closes.

It would be better to have the FV7 safety switch wired between the two relays since right now the time delay relay bypasses the safety switch for five seconds during startup. I'm not too worried about this from a safety standpoint, but it could make it a challenge to debug the system if that safety switch ever trips inadvertently. In that situation the fuel pump would still run for five seconds, but it would not run once the engine started.

Wow, I've never seen this issue before with the Boyd's tanks...Following to see what the outcome is...
Great attention to detail, I am enjoying your work.

I forgot to report that I filled my tank with the restrictor installed, and the fuel dispenser did stop when the fuel level reached the bottom of the restrictor. The tank did not leak.

[pjmoreland]

I reinstalled the roll-over safety valve on the tank vent. I had replaced it with a regular open fitting previously thinking that maybe the valve was trapping pressure in the tank and causing the leak. This doesn't appear to be the case, so I figured it made sense to put it back on.

Nice work! Just ordered a set of stainless line from SS tube I'm also going to use the fuel tank mounting bolts I purchase from you a while back.

I think you'll like it. The stainless version wasn't available when I ordered my lines. I should have waited. All of my brake lines are stainless.
