Prime?

[Cartsrcool]

Just put some new fuel lines on my 99' 7.3 and not sure how to prime. I tried letting the pump run a few times but only ran for a short while and starten sounding like she was going to blow. Took out the filter nad bowl isn't even half full. What should I do?

Cycle the key on and off to cycle the electric fuel pump, you should be able to hear it when she gets all the air out, may take a dozen or so cycles.

Replace fuel lines? Did you do the in tank and prepump filter mods and replace the factory fuel fittings with rubber hose to eliminate air? One of the best mods I’ve ever done and for less than $40 and a couple hours it’s a great value.

I guess I didn't do it enough, It wont start now and the battery is dead. I took the filter back out and filled the bowl with fuel but she would't start.

Still won't start. Anything else I should try? I also just put on a 4" turbo back exaust on, i didnt need to do anything special there did I?

What exactly did you do to the fuel system?
How much fuel is in the tank?

I replaced the steel supply and return lines that go from the bottom of the motor up to the pump and when I couldn't get the old lines out of the flexible tubing that run along the top of the frame I replaced those also. I changed the filter at the same time. The tank is full.

Hook up your batteries so they'll charge. in case of emergencies, use ether. Not great for your truck, but works every time. And if you only use it once in the lifetime of your truck, it wont hurt anything. Ive actually used it a couple of times when i couldnt get it primed.

Not sure what ya mean?

starting fluid or ether. You can pick ity up at any parts store. Its mainly for gasoline engines. You give a squirt of that down your intake and the engine will fire off and it'll prime itself while it is running. Usually will run rough for a minute or two while the fuel system is catching up. May puff out some white smoke, but completely normal.

Just the same as my old 555 backhoe?
