what type of e pumps are you all running on your rig. i am interested in getting one for my beavertail 20 horse honda engine. i also wondered what pumps the gas, or helps the stock pump, pump the fuel into the carb. this one guy told me that the crank case hose attached to the engine does that task and it needs to be hooked up all the time. just curuious. i am having to pump the bulb to keep my engine running i am sick of it. help me out please.

same exact problem with 24hp honda beavertail. I am waiting to hear what kind of pump these guys recomend. Is your tank up in the front of the boat? If it is, it confirms my suspicion that the distance is putting too much of a head load on the pump; kinda like hooking a 1hp jet pump to a deep well, you aint gonna get no water.

I don't have the part number, but the pump comes from NAPA. I'm not running one yet, but I helped my budy hook up his. Its mounted on the transom right below the motor. We just spliced into the existing fuel lines and wired it to the key switch. Now its just turn the key on, wait a second or two and fire it up.

do you have to put a fuel pressure regulator on it or just get a low gph pump?

Autozone has a mr. gasket low pressure pump. Believe its 1-3.5psi which you wouldn't need a regulator to run. You can get one from anywhere just try to stay under 4-5psi.

The hose you disconnected is what creates the vacuum for the stock pump. Hook it back up and you may be back in business. Why did you disconnect it in the first place? I would try to use the stock pump if possible.

i just put a napa e pump 5.5-9 psi. and it run's fine.

I've heard you can damage the float in the carb by pushing too much pressure. These motors/carbs were designed to run on a low pressure system... I thought 5 was the magic number to stay under, but could be off.

Mr Gasket 1-3 lb would be all you need. They didn't have one when I was in the store so i bought a 3.5-5lb. I wouldn't go above that for the reason CB mentioned.

how long will it take to mess something up if it's to much pressure?

Don't really know and it may not ever. You're right on the borderline, or what I thought was the borderline, and may be okay. But you may also look in to getting a regulator...

I read the fuel pressure thing on here. Try searching and see what you can dig up on it.

thank's cb i think i will get a regulator i dont want to have any problem's.

yeah you can get a regulator and get about what ever psi you want.

1-3lbs is what I have read. Correct me if am wrong...

it really doesnt need much. just enought to give it a little boost then the stock pump should carry the rest.

i know some one will correct me if i am wrong.

You don't have your stock pump hooked up properly, so it is not working. I would try to fix it before adding another piece of electronics to your system. Just something else to fail, and should not be needed. 9/10 times you have another issue in your set up that is causing the problem.

And if you add an e-pump, you might as well bypass the stocker. It is no longer needed, and the e-pump can damage the diaphragm in the stocker.

If you do decide to use an e pump. You don't need a primer bulb. The pump will have no issues priming the line. Hell as long as everthing is hooked up properly and you do not have any air leaks, you do not need a primer bulb if only using the stock pump.

Okay that is a much better explanation!

If your tank is in the rear of the boat, I'm gonna say you are wasting your time and money with an e-pump. Hook the stock pump back up the way it is supposed to be, and make sure your connections are tight throughout the system. The stock pump should not have any issues at all pulling the fuel 5 ft. What size line are you using? Anything over 1/4" is too big...

On the pump, there should be one line that goes to the gas tank (or primer bulb, filter, whatever is in that direction), one going into the carb, and one going in to the crank case. The vacuum doesn't work unless all three are connected.

After you make sure everything is connected properly to the pump, get a small tank and run a line straight from the pump into the tank. Fire the motor and see if she runs. Let us know what happens.

Look at your fuel line too, should be marked what size it is.

Well, for my boat moving the tank to the back of the boat solved my fuel delivery problem. I ran two tanks of fuel through it this weekend without so much as a hick up, got into some really nasty stuff that bogged the motor prety good too, still no issues. Good luck with it!
