Just converted mine today with the Mr. Gasket 42 electric fuel pump 1-4 psi I mounted it under the right side panel. I just disconnected the old one and just left it there. Removed all the old fuel lines and re ran the new ones from the fuel tank under the seat and to the left side under the side cover than back up under the tank to the carb inlet. It was a piece of cake. Works great. Black and Blue is your power and green is your ground. Bike even seems to run better. Total cost with new fuel lines aswel was $ 60 Bought fuel pump from autozone and fuel lines too. The stock fuel system by Honda is not very good or reliable.
Hey thanks so much for posting on RU-vid that was very very helpful. I have spent the last several weeks trying to figure out why my bike wouldn't start and you figured it out in your video. That was extremely helpful ... thanks again Chris
Just found this video . Bike has been down for 3 days. Removed pump and changed to gravity feeding the carbs . Started working. 5 minutes to remove pump and reconnect hoses and I'm back in the wind. Thanks!!
You don't need the pump just go right to the carb . They only added the pump for government regulations that is no longer in place . If you do just buy another pump just remember you can cut the line between the cut off valve and the filter and add a T ,a short piece of line leading to a small plastic shut off valve like you would use on a lawn mower line and another filter and another small piece of line to another T and join that into the line that goes into the carb . This way if the pump ever stops pumping again you can just open the cut off valve and gas from the tank will go to the carb and you can cruise on down the road .Once the valve is on and you see there is no difference in the pump and the gravity fed line at any speed or amount of throttle you give it , you will probable never turn the valve off . I think I paid about 15 dollars for the 2 tees ,piece of gas line that you cut to go between the fuel cut off valve and filter ,small filter ,10 small clamps and shut off valve . Its worth 15 dollars to never get stuck on the side of the road even if you still use the pump . You can do this on any bike that the pitcock is high than the carb .
No The float keeps the right amount of gas in the float chamber . You will never use all the gas in the chamber even at full throttle . This is not a fuel injected system where there is no float or float chamber . All the pump does is sends gas at the same pressure as a gravity fed system would . The float setting is what determines the amount of gas in the chamber at all times . There use to be a EPA regulation for a few years that was trying to make it so the gas would stop flowing to the carb when in a accident . But of course they couldn't do it on a motorcycle that wasn't fuel injected. because of the float chamber . But anyways a carbs float chamber is sized to hold more fuel that it can use even at full throttle forever. You only need a pump if the tank is lower than the carb . In a lot of bikes now a day the tanks are lower than the carb so you have to have a pump but on the bike in the video and the vlx600 the bottom of the tank is above the carb so it can be gravity fed . The guy in the video could have attached the line he has going to the funnel to the gas tank and it would run till the tank was empty .
steve dental this is some good info. I have an 07 shadow spirit 750 and I think my fuel pump is going bad. 65-70mph on the hi-way sputters/hesitate then it slowly died. It wouldn't respond to throttle. After 5-10 minutes on the side of the road it started back up but only good upto 55mph. If I go beyond 55mph it'll sputter and die again.
You can just run the gas line to the carbs with no fuel pump and they will run just fine. The problem is there is little room for a filter in between the tank and the carbs.
hey, demarcoz11, what happened to me was last year on the day of the eclipse, I was running back out of the mountains at the end of the day and my 750 spirit died. I eventually found out that the fuel wasn't making it past the pump, so I rerouted the fuel to bypass the pump with the hoses that were there, and it ran fine. it ran fine for months, in fact, but now, it doesn't like to sustain 70mph for very long once I burn a gallon out of the tank. It's because there's not enough 'head' pressure. when you have that funnel way up like that, that more 'head', you understand what I mean? it'll run without the pump, but it does have the ability to suck fuel faster than gravity can provide. I'm shopping for a new pump now. you either got to go with $100 for oem, or $32 for a 2 year warranty off ebay
