It might be a piece of cake to fit......but how do you reatach it and the sender back to the car. I did the swap allright , incidently the "ugraded" pump in situ is apparrantly a VN pump it's about 2/3 the size of the stocky and just couldn't hack it. I spent about 2 hours trying to fit the pump back in but just couldn't figure it out so they are just sitting in there ( the way they were when I opened the tank up)
Got the 040 pump through my local Aussie Auto for $290 Alderly store, 2 hours from phone order to pick up.
addit: Incidently the 040 fuel outlet contains a one way valve, even if you remove this the inside diameter of the outlet is only about 3.2mm. I assume everyone does as I did and threw the whole thing away replacing it with an outle inside diam 8mm. Maybe this is why SydneyKids quoted output is so much higher than the Bosch site's figures
