is a cossie fuel pump a straight swap for a s2 item ?

 

think so, have one on mine and don't remember it taking any extra work/bits

 

is it actually any better??

 

was fitted as was running a 5th injector
plus my s2 pump had possibly been on for the 190'000 miles the car has done

don't know much about it to be honest just remember mine being swapped over
only difference i have noticed is it makes a different noise to the old one lol

 

the only other thing i know about mine was the voltage was low to mine when it was checked

needs to be running 13.3volts at the pump minimum

 

Yesh

If your guna be loooking to tune up in the future then it would be daft not to upgrade. Higher flowrate/delivery pressure

As said above though your wiring needs to be in a good state, if its corroding and breaking down the pump won't work to full effect, but thats pretty much the same story for a standard pump aswell
