My opinion is that it is enough to show that the fuel pump is working okay.Ok did the fuel test using the key (starter) instead of the primer lever. I have a gear reduction starter so it spins faster than stock. This is about 6-7 seconds of pumping and yielded say 3 oz of gas. Much more than the primer lever method but is it what it should be? I will wait for answers before doing anything. Bruce
BUT that does not mean that you do not have a supply problem going to the fuel pump. So at higher speeds if you have a restriction in the supply line you would not be getting enough fuel to the pump to maintain higher speeds.
I believe you need to now look at the line from the tank to the pump. It does not take much of a restriction (or in my case a bit of RTV gasket material ) to either plug or impede the fuel flow.
Try opening the fuel line prior to the pump and see how that flow is. Depending on how full the tank is the flow should be a 1 to 3" stream . I would also try some compressed air down that fuel line. Also look into your tank for anything floating on the bottom. This is all best done outside the garage as it gets messy and dangerous with the spilled fuel.
I ended up draining my brand new TR3 fuel tank to find and clear out some small bits that had totally stopped the fuel flow.
