cheap fuel pumps

[andym]

I went to start my bike earlier and it would run for a second or 2 then just die... turns out the fuel pump needs replaced (or repaired).

Turns out it's the same one that's on the VFR, just with a different plug.

I had a look on ebay and found these ones:

The only difference is the plug and a fitting for a pipe on the plastic housing (anyone know what that's for?)

Anyone used these? As the proper ones for the zx9r are around £75-£85... just because the plug is different

OK, not bikes but I have had huge issues with Chinese crap fuel pumps on boats. I now only fit Facet pumps but I'm sure there are other good ones around.

I just grafted the Honda plug from one of my defunct pumps on to the wires of the Facet and zip tied the pump to the frame.

Yes, they're shit.
3 weeks, it was totally noisy clicking and high current draw.
They replaced it and same again.

You get what you pay for usually, I sourced the real deal Honda one cheap from Israel for about 37 quid delivered and that's been in about 2yr now.

The fuel pump arrived yesterday and just fitted it about an hour ago, and the bike still ran like shit and cut out after a second or so.... although the fuel filter is full now.

So I took the tank off again, had a look for the ignition coils to make sure everything was secured (because I didn't want to take the air filter off), couldn't find them*... I could just squeeze my hand under the air filter to check the spark plug caps were secure.... found cap 2 & 3 were about 1cm higher than 1 & 4

All caps secured and bike is running fine again.... strange that it was running fine 1 day then developed this fault the next




* Only after taking the bike a short run and putting it back in the lock up did I remember the coil is part of the spark plug caps

My cheap one lasted 3500 miles, when it broke it was a nightmare, I couldn't work out what was wrong. I thought it was just the heat, possibly the spark plug rating being wrong as the caps were sparking, fuel came out the pump yet the bike kept stuttering and dying however it worked for a while once cooled down but gradually got worse.

The fuel pump was very hot when I finally removed it.

I've ordered another cheap one anyway for £12.50

I'll get a proper one next time, I thought the cheap one I had was bad as it clicked loudly from the start. I managed to get a partial refund on it so didn't cost that much in the end.
