    I've only done 100 miles in mine so far. It fuels the car fine and mine is starting first time but other people with the 290 lph pump are having problems. Thats why i suggest the 255 lph due to people not having problems. 255lph is fine for a standard M3.

    Fitting is pretty much the same, but you will need to get a mix box of connections to crimp onto the oem wiring.

    Tricky one this. Personally I would just buy an OEM one. But if you do buy something else, you should reuse the oem pipe from your existing fuel pump. I read a thread a while ago that this was the cause of issues of the car hesitating to start first time. Something to do with the pipe holding pressure when you turn the car off.

    :thumbsup:

    It was the lower rated pumps. I went for the 340 rated pump because of my charger but others have also followed that route and no one has a problem with it.

    Use oem pipe and the new sock that comes with the kit. Be gentle with wiring and follow the horse power freaks DIY guide and its pretty simple.

    Just ordered mine as I've started to get a loss of power / miss when cold. Dealer wanted £462 + VAT when I spoke to them this morning but couldn't supply due to a severe backlog on them.
