No fuel...

[Fullspectrum]

...I have a ?78 35 HP Evinrude and it just recently quit taking in gas. When I prime the pump on the fuel line?it will not suck in any fuel. I replaced the entire fuel line from gas tank to motor and bought a new gas tank and it did not solve the problem. I called my local marine shop and was told that it could be my fuel pump, which will run about $45 or so.

Do you think it is my fuel pump and is that something I can install myself? I did take it apart?it?s only 5 screws and the fuel line?doesn?t seem hard at all if it?s just ?plug and play? type installation.

Let me know, thanks!

Re: No fuel...

You should be able to pump fuel from the tank to the engine and in fact keep the engine running by just gently pumping the priming bulb. If you cannot do that there is a blockage somewhere.

Take the pipe off the inlet to the pump and make sure you can pump fuel though to there. If that's OK refit the pipe and take the other one off the carb inlet and make sure you can pump fuel through to there. If you can't the problem is in the pump. Are you sure you put it back together correctly? Did you put one of the valves back in the wrong way round.

If you can pump fuel through the pump OK but not fill the carb then the problem is in the carb but it will only be the float or the float valve stuck or the float valve blocked.

There is no problem replacing the fuel pump if that is necessary. But identify the problem don't just keep replacing parts without proving that they are faulty

Re: No fuel...

The motor will use whatever fuel that?s available, which is very little, and then shut off due to the lack of fuel.

When I hook the fuel line on and prime the bulb?I do feel very little fuel to none being sucked in. Once I disconnect the line from the fuel tank and prime the bulb?I could hear it sucking in air.

I first thought that the bulb or the two valves on each end on the fuel line went bad, so I replaced the entire line and bulb with a new line system. Hooked it all up, which did not solve the problem.

I figured that the line was still able to "suck," So I decided replaced my 6 gal tank with a new one, which did not work either.

I took my fuel pump apart and washed it out, which my manual suggested and that did not work either.

I called the marine shop and was told that my fuel pump probably went bad. They?ll charge me $45 for the part and $65 an hour for labor.

I'm not willing to spend that much money as of now.

Any other suggestions?

Re: No fuel...

If you think it is the fuel pump why dont you get a rebuild kit instead of the entire pump. The kit is available here on iboats and usually run about 15-20 bucks. I recently rebuilt mine on my 83 rude 75 hp and it was fairly easy.

Re: No fuel...

It might be interesting to raise the gas tank so that the pump does not have to lift the fuel just to see what happens. If it makes the engine go then it does point to the pumpas the trouble.

There are no OEM spares listed for the pump, just the filter but I believe non OEM kits are available to overhaul pumps. Hopefully that includes yours. I have seen the source posted on here but i do not have a note of it . Sorry

Maybe npd4432 will tell us where to get the overhaul kit.

Re: No fuel...

This should be the one for your 35hp

Re: No fuel...

I'm completely lost now...I just bought a new fuel pump for $90 and it's still not working.

Got new fuel line w/new bulb, new fuel pump, new fuel tank, and a full tank as well...still not working!!

What the hell?!

Re: No fuel...

At the risk of repeating myself endlessly, you need to find out what is wrong before you start replacing stuff, FS.

You have replaced the tank, fuel line and fuel pump and you still don't know what is wrong.

I wonder how you reached the conclusion the the primer bulb was not moving fuel. Please explain, and explain what symptoms led you to try that anyway.

It is too late to test the tank vent and pickup, the primer bulb, the connectors on either end of the fuel line and the fuel pump, though a simple test of each could have eliminated it as a suspect and prevented the waste of time and money.

Though you haven't said so, I must assume that your engine won't start or you wouldn't have been messing with it.

Disconnect the hose into the carb and put it in a clear bottle. First pump the primer bulb and see if fuel squirts into the bottle. Then turn the engine over and see if you get spurts of fuel into the bottle. If both work that means all the stuff you replaced works. If not you have made an error in hooking new stuff up.

Now go to the carb. Squirt some fuel premix into it and try to start the engine. If it starts, then quits after a few seconds your carb is gummed up and needs a thorough cleaning, with particular attention to the tiny orifices that open into the carb throat.

Let us know what you find and how it came out. If she still won't start we can go from there.
