Facil instalacion, fabricacio y materiales compuestos.VDO fuel pump was the OM version that was in my e46 325i m54 4 sedan 2005. Car started right up, also bought a new battery as well. The one knock is UPS shipping took forever! I would suggest using USPS for deliveries to bmw enthusiasts like myself. We like to fix stuff fast! But overall don’t buy any other cheap version. You will be left stranded on the road!!Item was as advertised. Easy to install. Thanks again.I bought an off brand thinking it would be fine, it had good reviews so why not. Well after two of them didn't read fuel level properly I decided to get and OEM pump. Why didn't I do this the fist time. This one worked perfectly out of the box and fuel level is correct now. It does not come with a new gasket so order one as well. They aren't expensive and gasoline is a serious chemical so don't cheap out and try and rely on a 10+ year old gasket.Went in without issue. I did not order a new gasket as the existing still sealed. Also, no Ned for a special tool to remove the locking ring. Screw driver and a rubber mallet. Dispite what you read, install the rubber gasket first on the tank, then the pump. Much easier this way.works as promisegerman partsfor 2003 bmw 325ciI bought this in Dec and it is suppose to have 1 yr warranty, the hose failed and left me stranded on the interstate. The seller refused to be of assistance and stand behind their product. I suggest you look for part by a quality company that will stand behind their product and where their product will last longer. This should not fail in less than 1 year.Worked and fit just like it should
