Andrew just in the past I have used them so the fuel delivery stays at correct pressure you have mentioned an adjustable reg so it's in the realms of the unknown for me, I had a mini turbo which needed 3.5psi constant for fuel, the reg was a standard item none adjustable so issues sometimes occurred where the engine idled fine but under load it would be starved of fuel,,,, the fix was to use a return feed and the delivery fuel lines were not to have a diameter less than 8mm

I had not looked into getting a new manufactured diaphram from MAC or similar. One of the other reasons I opted for electric with a Filter King is they have some ability to "push" the fuel through in a more consistent manor which I am led to believe counters the effect of the modern fuels which are more prone to vapourisation. Anyway, I am fairly confident the system I have rigged will work ok, as long as my pump is providing the necessary volume.

It might be worth looking into it. They are rather cheap. The problems I have had were with a very hot engine being shut off. This I found had the fuel evaporating from the carb bowl after the heat transferred up from the block. With the primer bulb I just gave couple quick squeezes and I was ready to go. I found with the electric pump I kept getting flooding problems.

Good idea Jordan. I have already had a couple of flooding issues, namely that if you leave the ignition on it will overcome the carburettor valve and flood the engine as you say. I could rig a seperate switch for the pump I suppose but not sure its an ideal fix. I need to get it out and run it properly to see how the pump fairs in operation. Yesterdays trip was awful as I had forgotten to tighten one of the main pick up pipe nuts, and hence got starvation. Been raining all day today, so not been able to go for another test drive but maybe tomorrow I will. Will report back thanks guys
