I am changing me fuel pump cause mine is f**ked but not sure what pump to replace it with. I am in the middle of building a high spec zvh, some people say the standard one is fine for up to 400bhp but others say to use a saff cossie one? What you lot think????

MK5RST

saff cossie and RST pumps are exacly the same, use the standard RST pump

Rallyesport

They are not the same, the cossie flows slighty more at 3 bar. The part numbers are not the same eiter.

MK5RST

slightly more, how much more, the part numbers aint the same but the pumps literaly are

MK5RST

How much more

Bosch 0580 254 941.

Fits S2 and Sierra Cosworth.

The S1 and S2 pumps are different. The S2 pump is physically bigger and won't fit in the cradle.

Rallyesport

S2 is 0580 254 910.

3.25 l/min @ 3bar for 910
3.67 l/min @ 3bar for 941

why not go for a bosch 044 pump , otherwise known as the GRP A pump

Drjones

what car is this for s2 or cossie

MK5RST

we are all assuming its the S2 pump as its an RST Forum

The 044 is neither Cossie or S2. It won't directly fit without an adaptor which can be purchased from A1 Rallye Sport.

However it is totally unnessesary unless you want over 400bhp in which case you will need the 044. The 941 will suffice up to that limit.

The 044 will flow 200l/h at 5 bar or 3.33 recouring per minute at 5 bar.
