Electric Fuel Pump

Post by Funky Diver »

OK, so somehow I've managed to end up with a Yamaha R1 fuel pump... a NEW one, for silly money.

These things retail at £536 from the dealer, and when speaking to the parts guy at my local Yamaha dealership the reason they are soooooo expensive is that they never fail. Now why have I bought it I hear you cry (or mumble, or not at all).

2 reasons -

1, it provides the fuel at the right pressure (3 psi) consistently (it's a pump and regulator in one) for the carbs I'm going to be running (ZX9R Ninja Carbs)
2, it was cheap as chips compared to a seperate pump and regulator - it cost me £20 posted when I offered a guy an out of ebay deal after he'd listed it twice and it hadn't sold (naughty naughty, lol)

Soooooo, here's my "issue". It normally is bolted into a hole in the bottom of the bike's tank, with a seal and a plate. Now I'm quite prepared to cut said hole, but then I had another thought. A self contained fuel reservoir JUST for the pump / reg, which is topped up from the main tank. Sooooo, my question would be this, is there a pump avaialable that will draw fuel off the main tank and then stop pumping at a certain level? (say with a float switch of some sort mounted in the transfer tank)

So which would you say would be the better option and why? Anyone done anything similar in the past with experience to share?

I'm erring towards the transfer tank idea - as it'll be less affected by cornering and the like, but then for a cleaner install having it mounted in the tank would probably "look" better and not have a small tank of Petrol sitting in the engine bay.

Good Idea :D

View of base / underside

View from Side

The "thing" bottom right, near my little fingers is the outlet pipe - This protudes downwards about 1.25" including hte base of hte pump (so about 1.333" from base of tank to base of pump, if that makes sense?

Height of inserted part (so above the flange to the top) = circa 6"
Diameter (of the hole it would need to be "in") - circa 3.25"

Part number 24 is the pump, 28 is the seal and 25 is the locking ring
