Carb not gettin fuel problem

My carb guy gave me some bla bla bla about not being able to save my J-tube vents on the carb. What is the best way to add on some J-tubes to the existing necks he gave back to me? The rear tube is very short to go over can I go inside? Maybe press fit some SS fuel line in the rear tube and press fit some ss fuel line over the front tube. The look glued in.

SHE'S BACK IN ACTION. well i replaced the fuel pump, drilled a hole in the flame arrestor. Put a fitting in there, and ran the back up hose to it. Took it on the the water and wakeboarded for 2 hours. Thanks for all the help guys

Out of curiosity, what is the purpose of that tube running to the flame arrestor?

If I replace my flame arrestor, does it need a special fitting to have that line plumbed in? My boat is 2 hrs away, so I cant take a look at at how the line is run.

I believe that is where the clear tube goes to the flame arrestor. the other two are the inlet and out let of the fuel pump.

I replaced the fuel pump on my '84 Commander 351W a couple of months ago. Like Yak3, Iby all my parts from Skidim.com. I've always have a good experience with them. Here's the link to the pump I bought:

i talked to the guys down there and they weren't to sure what I needed, so thats why I asked on here. I also have the guy at midwest correct craft talkin to his mechanics and is gonna give me a call on monday with what he finds out. But i just wanted to see if anyone here has gone through the same deal as me

ok well i have decided on a new fuel pump, but no one seems to be able to tell me what I need to get to make sure the fuel pump will work with my boat. If anyone out there that has a commander 302 and has replaced there fuel pump recently could tell me what and where they got it, i would appreciate it. thanks

well i put a pressure gauge on it and got nothing. I am curious as to if there is any difference between a normal fuel pump and a marinized one? i wouldn't see why there would be. If anyone could let me know I would appreciate it. thanks

My vote is that the problem is with the fuel pump or the filter screen on the carb intake. It could also be a stuck float valve in the carb.

Just because you have fuel in your fuel filter or water seprerator does not indicate a good fuel pump.

I would recommend this in this order:

Remove the fuel inlet hose to the carb, remove the large nut on the carb where the fuel hose connects to the carb and remove and inspect the thin filter screen. You will see what I mean when you remove the large nut. I think it is about 13/16" or 7/8" in size.

Replace the fuel pump. They are not expensive and it doesn't hurt to throw a new pump on anyway.

If the engine still does not get fuel and you have fuel at the water seperator rebuild the carb.

You can get a fuel pressure gauge, install it and test fuel pump pressure but I think the cost of a new fuel pump is not that much more expensive (I think) so why not just throw on a new pump?

Keep us posted. Someone on this site will point to the problem and the fix.

double check the hose connections on the seperater and make sure they are tight and that they are going in the right direction. There should be a couple of arrows on the casting indicating the flow direction.

I also wanted to mention as well that there is nothing in the sediment bowl, its just old and discolored and the picture makes it look like there might be something it in.

Man I haven't seen a sediment bowl since I was on the farm as a kid. Our International tractor had one that would catch dirt and water from the tank. Depending on how it's installed it could be used to filter or indicate pump failure. If it's installed as Yak3 describes then it would take the place of the clear hose on the newer style pumps. At any rate, something isn't right in that picture!

By looking at that picture it appears that your sediment bowl is not full, or is that water on the bottom? That bowl should be full to the top at all times. Loosen the thumb wheel, dump and clean the bowl and reinstall. Don't tighten with pliars or you'll break the glass bowl. Crank the engine and the bowl should fill quickly with fuel giving you an idea if your fuel pump is any good.

ok so that is the fuel pump. My initial thought was that it was the fuel pump, the only reason i 2nd guessed myself is that I thought if would of been before the "filter" Yeah I will fire it up and see if I get fuel, but like i said, when i poured gas down the carb and started it, she fired right up, so the carb shouln't be the problem. thanks for the help

Well I am only 22 so all of my fuel knowledge lies in Fuel Injection some maybe some of you wiser guys could give me a hand with my 78 ski tique. My brother in law fired it up the other day and it ran for like 30 seconds than quit. Then never started again. First thing I thought was fuel filter, so I pulled that, and the it was full of fuel, so it doesn't seem to be that or the fuel pump. Also does anyone know if these engines have electric fuel pumps? I don't hear the pump turn on with the ignition but I also noticed the fuel hose runs directly from the tank to the filter. After the filter it travels up to the part that I am thinkin might be a water/fuel seperator, but am not sure. here is a few pictures I have taken. If anybody can give me any help I would really appreciate it. BTW, i did put some fuel directly down the carb and it fired, so I know the problem lies between the filter and the carb.
