Best way to prime fuel system?
I have an 02 Freedom that I have been re-building. I am ready to start running fuel through the system. What is the best way to prime the system rather than just letting the motor crank over and over? Can I manually engage the fuel pump through the electrical box? What would be the best way to do this? Thanks.

For Carbureted motors, goto walmart or your local sporting good store with a marine supply and buy a primer bulb. buy the one wiht the 1/4 fitting. Install a short peice of fuel line and connect one end to your carb abnd the other from your supply. I just primed a GPr tonight with this and works perfect. I do this everytime my carbs are off. Its the safe way to repack your carbs and have it crank less from dry starting.
check this link out.
I keep one of these in mytool box allthe time. Best little gadget to save time.

Well, I was just reading your thread over again, does it have an electric fuel pump ? Is it EFI ? It should pressure up itself prior to starting.

No, it is not EFI but normal carbureted with a single 40mm Keihin. It does seem to have an electronic fuel pump or "fuel sender" as the manual calls it. It does have a line coming from the bottom of the crank case up to the "fuel pump" on the carburetor too.
Do you think the bulb will still work?

Mix yourself up a little spray bottle of premix. Pull the 2 acorn nuts off and remove flame arrester cover. Spray in carb throat while cranking. Keep it running on the bottle as needed. Should pick right up.
(keep face away just in case)

Now that is a pretty clever idea, except for maybe the "just in case part" LOL.... Thanks.

your fuel sender is the fuel level mechanism , if you dont have a fuel pump than your system is siphon pressurized means you can have any air in the system do what rx is say an make sure there isnt any air in it

It is a comfort to know that I am not the only one who deosn't always sleep...............
Thanks for the info on the "sending unit", I had a feeling at that was for was to pick up the gas and for the fuel guage. It didn't make any sence to have and electric pump and a pump on the carb. It has been a long day. Thanks again guys.

Man, there are a few early risers around here. LOL
I have a primer on my carbs so it's easy and convenient to just inject a little spray into the carbs and pump as neccessary until it runs.
