Well I guess this is what I get. Haven't started or ran the boat in about 8 weeks. First thing the batt. is dead so I charge it over night. So first thing this mourning I try to get her running. :( No go. Drain the water seperator put it back on and still nothing. But one thing chaces my ear, the fuel pump won't stop pumping so I take the water seperator off again and find theres no fuel in it. :cry: Now keep in mind I was planning on taking the boat this weekend and leaving right after I stuff my belly with Turkey. Not looking good at all.
So heres the question. I fill the water seperator with fuel and bamm fires up and runs like she's never missed a beat. Now the problem. The fuel pump will keep the motor running but once the seperator is empty it shuts off again. If a pump was to go bad would it have enough to keep the motor running and not enough to pull it up from the tank? And lastly where can I get an Aircraft fuel pump on Thanskgiving? :x :( :cry:
I think I'll be buggy hunting this weekend.
 
You might want to check the lines from the fuel tank to the fuel seperator. Do you have anything in between them that could get plugged up? Also you may want to make sure the tank is vented properly, I have seen mud daubers build a nest in vent lines and cause fuel starvation like you are experiencing.

How much fuel pressure do you need? I'm thinking electric autoparts pump.

I would rig a gas can to feed the pump without the filter and see what happens.

Check all the lines and could not find any clogs. It just does not sound right. This will be the second pump in 15 months. The pump is an Electric Carter.
 
Aces,

Gotta echo Larry's post, look for proper venting(mud dobbers probably).
Gotta be that or the suction hose from the tank, or problem with the pick-up in the tank.

Aces,

Have experience with exactly what you describe. My engine and tank had sat idle for several months before I bought them from a fellow in Tarpon Springs. When I swapped the engine and metal works over, the fuel pump could not feed the engine.

After more than a little cussing, I finally found my problem. The fuel had turned to varnish in the tank and that varnish manifested itself in strings that looked for the world like angel's hair.

I removed the tank pick up tube and found this hairy mess in the check valve. My check valve was located where the tube met the tank. I dug it out mostly with a Leatherman and blew through the valve till I finally got it all out. Dumped the tank and never had another problem with it. Now, I treat my fuel tank with StaBil if I am not going to be running the boat for a while.
 
You have to replace the water separator.

A water seperator absorbs water and then will not let fuel through. Replace the element and you'll be good again.

We see this a lot on tractors where I work.
 
Thanks for the replys. Just got back from the woods and did leave the boat back. This week it looks as if I'll start in with the tank and water seperator and then move to the fuel pump. Sure where alot of boats on Lake Kiss this weekend.
 
Just a thought: Congress Auto carries Holley Red fuel pumps in stock. I think a Holley would be a better bet than a Carter.
 
I agree, graywolf .... Holley Red is the only choice. Not too much pressure, and as reliable as an anvil.

No Help finally got around to it and still no fuel coming up. I guess the next step is the pump. What is the Ideal pressure for a 0540 angle valve?
Thanks
 
This morning I just retrieved the last stuff I hauled out ahead Hurricane Rita. On item was the Lycoming overhaul manuel and it was sitting on top of a pile waiting to be put away.

According to the Test Procedure section, carburated engines should have 2 to 6 psi at the entrance of the fuel bowl chamber. Injected engines should have between 18-28 psi.

With that said, I would agree with the others. That Red Holley works great on an angle valve 0-540 and I think it pushes around 7 psi. (That is what on the Kline I run with an angle 540). I believe Jegs sells a marine version and you can get rebuild kits for them as well.

Carters have a great reputation, but I have had bad luck with two of them. Of course that could have been that I had done the wiring. :lol:
