Which hose???????
 

Does any one who owns a 84ish 300d know what size hose the fuel return lines are. i bought a 4mm ext braided hose but i think this is a little too large. i think that the 3.5 mm available on fastlane would be better but it is only available in latge lengths! can some one take a look at it and give me an idea?
thanks!

It is the smaller hose...It comes by the meter because you should replace all of them, not just one.

Ok i am pretty sure it is the 3.3 mm hose but it is only available in 12M lengths for 50 bucks. is there any way i can get a shortr lenght??

With all due respects to FASTLANE for not making my purchase there (did not know about then until later) I purchased 2 meters from performance products. They sell the fuel injector bypass line by meter for $4.95 (winter catalog 2001)

FYI I no longer use performance because their customer service is awful. I had placed an order for specific tools and it went from in stock to back ordered to WAY back ordered. No one in CS could tell me the true story as each time I called I got a different story.

I now like to deal with Phil from fastlane as he is friendly, knows what he is talking about and workd for us, the customers IMHO.

Part number
 

I just bought some here from fastlane and the part number is D1030-21332 sold by the 290mm section (around 1 foot) for $1.51. Since finding this site Performance Products has become an old memory for me:D

since you brought it up: the hose needed for the injector bypass hose(the really teeny one) is 3.5 mm. i got mine from a VW parts unlimited near my house after buying a 4mm hose from fastlane. the guy said here take what i have what i have left for 5 bucks, it was about 3 meters. my injectors are now bone dry and my mileage has gone Way^
