Walbro 450 Installation - the only fuel pump you need

[Rusty]

Finished off the wiring using some TE Faston Positive Lock connectors 341002, these fit in the T pluh off the original pump and are the same as came from the factory. £3-4 for 10 off ebay.

Final part of the puzzle will be a wiring harness off Alex.

If it out performs the 044 it’s most definitely going to be ok for a home fried car.

I've checked the pump I bought ages ago and it's a 255. I'm looking at the 450 but it am just wondering if it would be overkill on my 270hp chipped car..?
Just checking before I placed an order..

I've just ordered a bosch 044 from bosch and all the hardware from tps. I've got a3b so should have the 60mm basket already..

Thanks for the guide...Where has everyone sourced their 450 pumps from?

Just bought a Walbro 450 LPH (274 high pressure version) from Fuel Performance UK

Walbro GST520 will do the trick if want much more horsepower later on to

Lol, the 450 is good for 700hp, I’m pretty happy with 400 already

Here’s the Walbro 450 pump in the RS4 basket. There’s about a 10mm gap all round.
My plan is to use a length of ethanol grade fuel hose to make an O ring which will fit snug round the top of the pump and be held in by the normal top clip. I did the same mod to the bottom of the basket as Rusty to allow the pump to drop right in, except I left the original filter mesh in place.



Original RS4 pump in the basket for comparison

The Walbro isnt noisy at all right?

Supposed to be really quiet, I haven’t powered it up yet.
