Evinrude 15 fuel line and tank problem

[imported_Warren]

I have a 15 hrs evinrude Mod E15RCVD Ser# E0658687 I would like to know the year or if its a good motor? Just got it a month ago. Runs great but for some reason I have a really hard time getting gas to the motor. I have gone through 2 brand new tanks now and 2 complete feul lines with primer bulb and still have to pump the bulb and push in the ball at the motor for about 100 pumps before I get sprayed in the face with gas and plug it back in. Then it will run all day, first pull everytime. Sometimes it seems like the primer bulb is just pushing and pulling with no pressure the other day at the lake when I was broke down for 3 hours at the dock I took the bulb apart and put it on backwards, same thing,push and pull Can I put an electric fuel pump on this thing? I take it out to the ocean and don't want to get stranded and die out there.......Thanks in advance for any help......Warren

Hi Warren and welcome to the forum.<br /><br />From the model number you posted E15RCUD, this is a 1986. The 9.9's and 15's are great running engines. <br /><br />Tell me about your gas tank. Is it a OEM tank or generic? Meaning, is it a tank made especially for Johnny/Rudes or is it an after market tank. If it is after market, you may need to vent the tank. Most tanks have a small knob on the fill lid that acts as a vent when open. Is your fuel line OEM? Look at the primer bulb and you will see an arrow. This should point to the motor or what would be the fuel flow path, from tank to engine. OEM fuel lines and tanks self vent. So try looking for a vent or crack the fill cap and see what it does.

Goofed on the year, 1987. Check the site below for year.<br /><br /> http://mitglied.lycos.de/old_omc/evinrude.html

Warren..... Double check that model number as it would appear that you have transposed a letter somewhere. We need the proper number to tell the year. You've listed it as E15RCVD. <br /><br />The fuel primer bulb is designed to pump in one direction only. If there's an arrow on it, the arrow would face towards the engine. If there's no arrow, remove it from the line, hold it vertical and pump it. Pressure should be exerted out the top of it. If not, reverse it and try again. Whichever end exerts pressure would face the engine.<br /><br />With the bulb installed back on the hose and conected to the tank and engine properly, hold the bulb in a vertical position and pump it. It should draw fuel, pump it to the engine and feel solid within a half dozen pumps or so.<br /><br />If the fuel tank has a manual vent, make sure that it is open. If air cannot get in the tank, fuel cannot get out of it.

Re: Evinrude 15 fuel line and tank problem

the origional tank I got with the boat is a metal tank with some inner tank plastic cup inside with a secondary screw in top on it and the reason I replaced it is because the rubber gasket was missing from the filler cap and didn't want the boat to explode due to gas fumes. The 2nd and 3rd tank are from the boat store and they are just standard 6 gallon $25 jobs that I had to purchase a fitting for. As for the primer bulb, its pointing the right way, I even tried to close the screw in vent on the filler cap and shake it up for push pressure. Didn't work and my girlfriend was laughing her ass off as me while I was doin it....Would take it in but don't have the funds right now...By the way the 2 new lines w/bulb were made by atwood.....Any more suggestions?

Re: Evinrude 15 fuel line and tank problem

OK Warren, try this but do be careful.<br /><br />With the hose hooked up to the tank, slip a small screw driver into the end that would connect to the engine to push back the little ball in the fitting. Put the fitting into a container and squeeze the primer bulb and see if the gas flows free. As Joe said, make sure the tank vent is open. If the gas flows free then you may have an obstruction at the engine. <br /><br />Look at the connector at the engine. Does the gas inlet tip have what would appear to be a needle coming out of the center? This is a one way valve. It prevents fuel from flowing back from the engine when the fuel line is disconnected. If there is one, push on the needle and see if it is free and depresses back into the connector. If it is stuck, this could be your problem,,,,providing you have such a connection.<br /><br />And another thing to try.....Pull the hood off the engine and find the fuel pump. It will be on the Starboard side. Where the fuel supply hose connects to the pump will be a big black cap with a large screw in the middle. Loosen the screw and remove the cap. You will find a screen on the inside of the cap. Make sure it's clean. Now with the cap off, squeeze the primer bulb again and see if you get gas that far. This will mean the problem may lay with the pump, I doubt, or in the carb, like a sticking float needle.

Stuck the screwdriver in and pumped the bulb. The gas isn't coming out unless I let the ball go and push it in like bleedin brakes (got sprayed in the face with gasoline again by the way). If I hold it in, it just pushes and pulls. The vent is open, even tried taking the cap off and trying it again. Dam I even took off the fitting at the tank and shoved the bare hose into the filler hole and same results. Its gettin dark so i'll try and take off the fuel pump cap tomorrow....Thanks for the help I wish I had you guys with me at the lake a few days ago.......Warren

Re: Evinrude 15 fuel line and tank problem

Warren, are ya' sure you got a hose for Johnson/Evenrude? Something just ain't click'n here. Do you know anyone that would have an OEM fuel line (One made by OMC/Bombardier) you could borrow just to see if that would make a difference? Keep us posted as to what's going on. I'd really like to know what wrong to!

Re: Evinrude 15 fuel line and tank problem

Dang...it really sounds like the check valves are in the primer bulb backwards. You pump the blub with the screwdriver in and it pushes and pulls. Release the ball at the connector and push it in again and gas flies out. Sounds like your building pressure up in the tank by pumping the bulb. Wish I was there to. Colder 'n all get out here. I'm ready for some sun.

Re: Evinrude 15 fuel line and tank problem

Yea I think so, It says johnson/evinrude OMC on the package. by the way could it be the problem that i'm running 100/1 oil ratio, 1oz per gallon in my tank? Seems a little lean. I may have to wait till next month and bite the bullet and take it in to a shop(when I raise some funds). The taste and smell of gas is making me sick. Had to soak my new shoes in Super Clean to get the smell off of em......Warren

Re: Evinrude 15 fuel line and tank problem

The oil in the gas should not make a difference. By the way, correct mix is 50:1. 16oz of oil to 6gals of gas. The 100:1 is to lean. I know. It's marked on the engine. But 50:1 will let your engine live longer. Get cleaned up, have a Bud and rest for the rest of the night. Sometimes that's all ya' need to see the problem the next day. Talk at ya' later.
