sqrlgtr 2,771 #1 Posted 20 hours ago (edited) Wanting to add an electric fuel pump to my 520H and was hoping to get some ideas/suggestions/pics of mounting locations. I done a search on here, but a lot of the pics are gone and not much about mounting locations but more about wiring. Pics don't necessarily have to be 520's only. I have everything to add a rear lift to the 520 so under the seat/fender may be out (looks to be really tight) but I havent had a chance to check it out good yet. This is the pump I will be installing. Thanks for your attention to this matter!!! Edited 20 hours ago by sqrlgtr Share this post Link to post Share on other sites
Bill D 2,801 #2 Posted 20 hours ago (edited) I substituted the NLA Onan pump for this Kawasaki pump. Mounting bracket is from a Kawasaki. If you go the electric pump route, connect the positive wire to the positive terminal on the coil. If the safeties are activated the pump will shut down along with the engine.

Mounting bracket is from a Kawasaki. @Bill D How does the Onan crank with that style pump. The hard to start after setting is only thing I have against the pump I have now it runs good just hard to start after setting for a few days. I put a one-way fuel valve on it at the tank, and it helped a bunch but still cranks over longer than I would like after setting. This is where I had planned on putting it but would like to run that rock shaft I got from you (WHX??) also. 9 hours ago, WHX?? said: Pan stand was out for paint.

sqrlgtr 2,771 #6 Posted 11 hours ago I wonder if anyone has tried to stiff one beside the motion cam control cage? Looks tight but sure would be out of the way. Share this post Link to post Share on other sites
Racinbob 12,928 #7 Posted 9 hours ago (edited) My 2005 Classic has it under the seat. That spot is filled by the filter on a hydro. The 314-H I no longer have. I was a bit hesitant because of the long fuel line run on my 76 Reborn B-80 but it works great. The Dino C-121 Edited 9 hours ago by Racinbob 3 Share this post Link to post Share on other sites

This is where I had planned on putting it but would like to run that rock shaft I got from you also. It still takes a little cranking to get it started, just like the original pump. I just don't trust the Chinese knock off pumps, so I went this route. Sounds like the check valves in your OEM pump are failing. BTW, I think you may have me confused with someone else, I never sold you a rockshaft. 1 Share this post Link to post Share on other sites

Also have replaced original fuse holder with weather proof one as suggested from members here thank you. 2 2 Share this post Link to post Share on other sites
953 nut 65,716 #11 Posted 6 hours ago Most any place where the suction of the pump will be lower than the bottom of the tank and the fuel hose will be protected from mechanical damage is good. The whole idea is to provide a net positive suction head pressure so the pump won't have to work as hard. They are great pumpers but lousy suckers. 1 1 Share this post Link to post Share on other sites
