We have an '81 Trogan with the Chrysler 360's. We just changed to the 1409 carb and made a huge difference. Also installed a pressure gauge to monitor pressure but the lake got too rough to do that. The first run went good for 20 min or so and the engine with new carb started dropping off like it was running out of fuel but would idle ok for docking. I am wondering what specs we need for an electric fuel pump. I'm seeing 2.5-4.5 @ 30GPH pumps for the 360's. Shouldn't the pressure be up at at least 7psi? Is that GPH on the low side ? Does anyone know what I should be looking at?
