Himalayan Fuel Pump

[Wiggy]

Hi All, just joined hence the total noob title. However i've been riding since the 70's, had my Himmy 3 yrs. Had no problems before now but here we are !!!

My fuel pump has stopped working, is there any way they can be repaired or am I up for a new one?
Draining the fuel out of the tank in preparation to remove the pump there was a considerable amount of crap in the bottom of it so i'm hoping the pump is just jammed with a bit of debris.
I changed the relays to Bosch ones straight away on purchase of the bike so hopefully it isnt the relay but I will be checking that.

If the pump can be opened, cleaned etc is there a cheat sheet for this?

Thanks for any input.

PS, i've also got a 2007 Electra 500, as a resto' project.

They are cheap enough that is probably not worth taking the chance refitting it - a search on this site will tell you where to get the cheapie.

Try briefly reversing the connections to the pump - this will make it run backwards clearing any debris that’s jamming it. Useful if you have a problem on the road, but may not be a permanent fix.
There’s an internal filter inside the pump unit, so it’s unlikely that tank debris is the problem unless it was there from manufacture. Others have had similar issues though, including iirc fibres from the filter jamming the pump.

Here is a fuel pump assembly disassembly and reassembly video. You could try cleaning the filter and doing the above suggestion. If you want to replace the filter or pump, the whole assembly is usually not that much more expensive. The bare replacement pumps, while available from the after market, don't have a check valve to keep fuel from draining out when disconnected like the stock does which can be an unpleasant surprise for some of the frequent maintenance needs. The replacement of the complete assembly is super simple and would likely serve you best as long as you do have power to it.

Incorrect, some may not have the check valve, this one does.

is your bike still under warranty? had mines replaced a couple of years ago while still under warranty.

Looks to be incorrect.

A customer at the vendor pictured in one of those pictures, Himalayan-Tools, reported in their forum the pump he received from them had a few annoyances and one is the issue caused by not having the same check valve as the OEM pump and leaking gas when disconnected for maintenance. There may be some that don't leak, but the one offered by Himalayan-Tools looks to have this same flaw.

I recently replaced my pump with a non-OEM pump for troubleshooting and it had what could look like some sort of a check valve on one end, but similar to what others who have tried these replacements report, it leaked when the fuel line was disconnected. It was about 15 USD delivered from Aliexpress ( Fuel Pump for Honda Beat Vario 125), was great for diagnosis, and is small enough to pack for long trips, but the OEM which was actually still good in my case will be going back in for convenience and some safety peace of mind.

TBH that customer should have returned the said fuel pump but proceeded to modify it to fit.

Didn't look like what the customer did was wrong, was the cause of his issues, or different from what many of of us would do. Also, the cost to ship to India isn't really attractive at least from my location.

Making the best of the situation when finding a 0.3-0.5 mm larger of input nozzle than the original, he simply removed a bit of diameter so it would fit together. The noisy pump and leaking fuel complaints he mentioned is what I experienced as well with my replacement purchased elsewhere and likely common for many non-OEM pumps.

For 20 USD extra, less if Himalayan Tools charged him shipping, current prices show a complete OEM fuel pump assembly could be delivered to the US. Considering drawbacks with non-oem replacements and the modest price that an OEM pump can be had, it can be money well spent to get the OEM when doing a permanent repair especially if the safety of gas leaking when the fuel line is disconnected or pump noise is a concern.

I do like the cheap non-oem fuel pumps, even with their problems, as a spare for travel or for troubleshooting. Mine from Aliexpress was very inexpensive, fit like it should, and recently came in handy for troubleshooting so was helpful to have on hand.
