Fuel Pump

[Olliew321]

Hi can someone please send me a link to the fuel pump upgrade.

What to do and what you need etc.

And how to do it.

Thanks

It's on my list of stuff to do. No link, but basically it's this:

New relay 30Amp or more, with a fuse. You can get relays with inbuilt fuse.
Put it next to the existing fuses.

Wire this to a good battery supply.

disconnect the wires that run to fuel pump. Use these to switch the relay on.

Run new heavy wire from relay to fuel pump.


The reason for doing it is that the original wires and drive were too small so there's a volt drop at higher currents. This can limit the flow of the pump.

Cosworth 044 bosh would probe be a good pump to use?

Do you want a pump for more engine power or just the wireing upgrade ?

Unless you're aiming for big power increases I'd steer clear of the 044 if I were you.

Thanks for the info.

Was looming at changing to the 044.

What BHP can the standard pump handle?

I took off the main supply from the back of the starter as you then don't need a long lead around or under the engine bay. The new relay is located next to the pump away from water spray and the fuse is directly by the starter connector for ease of access, very short cable runs and nice and neat.

As also done by jetstream to mine

you can upgrade to the M400 one which will go to 450bhp... unless you change your fuel system setup an 044 will struggle to suck fuel from the tank and start thus buzz badly which is why its not recommended.
