I finally had my fill of FI and ripped out the entire fuel injection in 30 minutes. I was finally able to clean my engine out nice Installed dual weber carbs. I'm going to hold on to my fuel injection if I ever change my mind or sell.
Question. I installed a new low pressure fuel pump so my lines are empty. When I turn the key, I can't hear it like my FI fuel pump. What is the best way to prime these when they are new? Everything is hooked up except for the throttle cable. Should I disconnect the fuel lines to get the air out of lines. I do not know if these are vacuumed or not is why I am asking. |

What carbs?
Is the pump actually running when you turn the key on? With carbs, when the pump is running it will deliver fuel to the carb float bowls. Any air in the lines will pass through to the float bowls and out of the float valve. Once fuel follows the air then the float bowls will fill with fuel and the float will shut off the flow. A double pump or two on the throttle will result in fuel coming out of the accelerator jets However, if you wired up your fuel pump where it only runs when the coil is producing power (like the FI does, and is a good safety feature) then you'll have to add a manual switch to turn on the pump to do the above. Or, you wire the fuel pump to also run when you're cranking the engine (the like FI does). |
