Well did not receive the priority mail with resistors from T Crook today. Did install the new fuel pressure regulator and took some fuel pump data while calibrating the EM2 for the fuel pressure. I had 2 gages that I hooked to the system. One reads 0-400 psi and is a laboratory instrument that I bought surplus. The other is a 0-100 psi steam gauge out of an automobile. When I dead headed a single Walpro pump, it read 105,100,95 on the lab,auto, and EM2(with default values). When returning fuel to the tank and no engine flow it read 38,38, and 53. I then assumed the 38 number was correct and rescaled the EM2 to also read 38.

I was concerned about my return line having a restriction in the tank since I added it after I built the tanks. I wanted it to return the fuel near the outboard end so that I could turn on the pumps if I added fuel without the oil premixed. Then when I run the pumps a few minutes it has a chance to better mix the fuel and oil before I crank.

The return line was disconnected at the firewall and pumped fuel with one pump into a gallon jug and measured a flow rate of 36 gph. I only have one return line to the right main. I figure that I will run this tank the first 1.5 hours, then the left or aux tank for 30 minutes, then back to the right tank. I feel very confident about the accuracy of Van's float gages. I added 5 gal to the right tank and it reads 4.8 and one gal to the port tank and it shows one gal. Turned on a single pump with selector on left tank. The gage hit the empty peg in one minute and the pump cavitated in another 40 seconds. This indicated to me that there is very little added loss in the return line since the pump pumps 36 gph whether it is going in a jug at the firewall or back into the tank.

Have to pull intake manifolds tomorrow because the rotor 1 primary injector started leaking when the system was deadheaded and we had 105 psi. Maybe it would have never leaked, but am glad to fix it on the ground.

Hope the US mail delivers my resistors tomorrow
