F225 yamaha runs only if I squeeze bulb???

[cmitchell2]

One of my engines will run only if I squeeze the bulb. It ran fine until I ran one tank dry. I switched tanks and idled to the dock and the next time I used the boat the motor quit. I squeeze the bulb and everything is normal. I had my brother squeeze it so we could run a few miles and fish. Any ideas of what my problem could be? I will be changing all fuel filters and fuel lines on the motor tomorrow but wanted to see if any of you have an ah ha moment and have had this same problem. Thanks

have you thought about fuel pumps going bad

[cmitchell2]

I am looking for all options. I believe I have a pump in my tank but my other engine works fine. I also changed the fuel water separators right before all this happened. Could the one going to this engine be a colporate? I was told there are 4 fuel filters on this engine. I am going to replace them all I guess??

[99yam40]

I have heard of autos having pumps in the tanks but not boats. Buy yourself a manual and check your fuel pumps

[mitch]

It is your low pressure fuel pump not working either blown fuse or pump stuffed when did this occur after storage or during use . Did you prime after changing filter

[cmitchell2]

It happened the first time I used the boat again 2 weeks after I had run the tank dry. The boat is a 282 grady white and I will check but several people have said that I have a fuel pump in the tank. I will check manual today. Does anyone know how many filters are on this motor?

[cmitchell2]

I did prime after changing filter.

I have not heard of any Gradys with pumps in the tank. Go to the Grady web site and ask. Check to see if you have a restriction in the fuel line. Remove the bulb from the fuel hose on the motor side and prime it into a can. It should keep flowing freely and not loose the siphon. If it does back track to the filter and recheck the seal on the filter mount.

pump is in VST tank

sounds like you have some restriction and manually pumping helps

look at the parts section here for your motor to find filters

looks like you dont have low pressure pumps,, ive never worked on a F series

***Update*** My fuel feed pump 5 amp fuse was blown. Problem... Changed fuse then ran engine and fuse blew within 2 minutes. Any ideas?????

[eddie m]

The pump is shorting or there is a short in a wire/relay connected to the pump. Nice to have twins. You can swap parts.

[cmitchell2]

That's a great point. The fuse says that it goes to the fuel feed pump. Is that different from the low pressure fuel pump?

[mitch]

Nope that is your low pressure pump = feed pump it is the one on the out side of the vst They do not like being run dry or with water you might try taking it of and cleaning it with some carby cleaner and feeding some wd 40 into it might have a gut full of foreign matter in it ? that try it again .
A new one is about $ 650 the blue wire is the + but be careful i have run clean diesel through them to clean and lubricate
check no 26 on link be low

Mitch, great name! So you are saying there might be a chance that the pump can be cleaned of junk and may work again. It worked for a couple of minutes which makes me believe that it is not shot and the fuse blew because it was struggling. I will take it off and clean it. Thanks

It will be intresting to see if trash got by your filters. Update please.
