One question, Can you find a regulator that will actually cut the fuel pressure down to the 3 or 4 lbs max that the carb needs that is of a high enough quality to do the job and how much more will it cost than a stock replacement fuel pump for that engine?

A new fuel pump for the 261 that doesn't have the vacuum pump for the wipers is 20 bucks from Rock Auto and a little over 30 from O'Reillys. https://www.rockauto.com/en/catalog/...fuel+pump,6256

Then is it the pump or the gasket behind it that is leaking? I'm just not seeing the wisdom of swapping to the high pressure pump and then having to buy a pressure regulator to cut the pressure to match what the carb needs. Plus if you go to advertise and sell the 261 before you pull it and are able to take a potential buyer for a ride in the truck the new fuel pump is a selling aid. Throw in that my experience says that being able to show someone how well an engine actually runs down the road is added value.
