Fuel pump & filters
Some advice needed.
What fuel pump and filters are recommended for a 2003 R1 BEC.
I saw this on ebay:

Well my plan is to use one of the following which a few others on here have done.
Range Rover pump
Does anyone know if the MGF pump will supply enough fuel for a BEC by the way?? They do look deeper than the Range Rover part or is that just because
it is extended here
??

Fuel pumps get complicated when you're dealing with carb'd CEC vs BECs as bike carbs like lower pressure than car carbs generally (so when
you convert a car to bike carbs you're better off using a bike fuel pump).
With throttle bodies and EFi it's a little easier as the fuel regulator on the bike throttle bodies will divert excess fuel into back to the
tank via the return line. You don't want a massive pump otherwise you'll just be wasting HP to power the fuel pump just so it can push
silly amounts of petrol round (therefore also heating it up).
All things being equal, if you get a EFi pump from a car with the same approx BHP as your BEC you should be fine.....

MGFs had a max power of about 110Bhp IIRC which could imply that the fuel pump won't be able to keep up. They may have over-rated the pump by
quite some margin. However, you don't want your nice BEC engine running out of fuel pressure when it's blasting it's nuts off. A
sustained period of lean running would be bad....
Unless you can find a datasheet on the pump in question the main way of finding out is to connect up the pump to the fuel reg and see how much fuel
comes out of the return line. Obviously collecting petrol into open measuring jugs is rather dangerous- but it's the method suggested in Corky
Bell's book on supercharging.....

Thats what i was thinking of myself - an MGF VVC only has around 135bhp and the ZX10R should give more like 180ish. Will go for the Range Rover efi
one myself then
Editted to say there is a 160bhp "Trophy" version so will try and find out if it uses the same pump

Paul, is there a disadvantage in using the range rover unit, because there is no pre filter to stop any particles going through it.
What is the depth required to fit the range rover unit?

Tom, I've used an Escort RS Turbo pump and an Astra filter. I also have a pre-filter on the tank outlet to catch large debris before the pump.
All have push on pipe fittings.

I havent got one yet myself (got a Pinto Tiger SuperCat to finish before i get on with my BEC) but so long as the tank is flushed out before use then
i cant see a problem with not having a prefilter as its obviously fine in the Range Rover.
This is the original thread that made my mind up to use this pump so
hope its useful anyway.

Fuel pump
Linky
See link
2003 R1 fuel regulator on the rail should lift around 40 psi
Fuel pump Spec from manual is:-
Pump type Electrical ----
Model (manufacturer) 5PW (DENSO) ----
Output pressure 94 kPa (2.94 kg/cm2, 42.6 psi)
We are running the vauxhall pump plus Vauxhall fuel injection filters either side of the pump on a 2006 R1 engine which yamaha manual says is the
same spec fuel pump as the 2003 model.
Pump pressure must be higher than the regulator lift pressure on the rail
Hope this helps
