Aftermarket fuel pump?
07 1100 Silverado

Started up fine as usual, ran a couple mins, then started to sputter and die. Tried to start after that and would try but never catch.
Having run out of gas on my first bike (oops) and had fuel pumps go bad in cars, it really seemed like it.

Per the manual I checked the resistance at the switch - shows an open (not the expected 1-2ohms) and when 12v is applied directly - nothing. Finally I bypassed the pump and went direct to the carbs - started up no problem.


So.... looking around I see many lower priced aftermarket pumps that look ~nearly~ the same and I'm wondering if anyone has used these instead of the OEM $150(!!!) model?

I would have to change the connector end which is simple enough, but what about the vacuum port on the replacement? The original doesn't have that.

OEM:

If you used one like this, did it work for you?

i think fuel pumps were put on carbureted bikes for safety purposes, so if a float hangs up when it's parked and you forget to shutoff the pet cock the entire contents of the tank don't leak out causing a serious safety issue. a low pressure pump probably doesn't deliver any more fuel than gravity would. that being said any low pressure fuel pump would work as long as it you can fit it to the bike. as far as that vent nipple i would put a small piece of hose on it and aim it rearward so rain cant be driven into it.
