fuel line question

[25thh0ur]

i have a late model m20 from a 325i swapped into my car and i noted that the fuel line coming from the fuel filter to fuel rail is cracking so i wanted to replace it but I'm stumped on which P/N to order I've came across both of these and want to see which one is correct, thanks in advance.

13 31 1 722 565

or

16 12 1 180 409

If there isn't anything special about it (one of those part numbers has a 90° bend in it that may be required) just buy it by the foot at the parts store. Make sure you get the high pressure fuel injection hose. I bought some and it was $4 a foot and mine was labeled "5/16 inch (7.9mm)". Be careful taking off the old stuff, I squirted myself in the eyes with gas and lost a set of contact lenses.

thanks man, can anyone confirm part number?

When I tap on those part numbers from my iPhone it thinks it's a phone number and tries to call it. So there's that. Glad I could be of help.

Call them and see if they know what part to use.

16 12 1 180 399 is the part number for this piece
13 31 1 722 565 is a long piece of fuel line with a right angle bend at the very end (used several places)
16 12 1 180 409 is just plain straight 8mm ID fuel line usually sold by the meter
