Since my fuel ines are now 16 years old (& about 1500 miles!) I think it's time for replacement. As soon as the garage reaches 50 degrees.
Here's the plan. Every rubber delivery piece, from front to back, is to be replaced. Though many will disagree, my plastic lines have no cracks & will remain intact unless I find a problem. Also, I want to replace all fabric covered hoses with the same. Every inch is to be replaced. And, if at all possible, all fabric covered hoses will be used - it's a CW 914 & I want it kept that way. Badger me all you want, but I'll do it my way if I possibly can. Since the car is now 35 years old, I've even found a couple of beautiful/original/new fuel delivery tubes. I know in 16 years a lot of parts have gone NLA, but I'll do what I can for one last change to factory - figure I'll be pushing 80 when they need to be changed again! After going through my parts manual I'm a little confused - so Now for some questions: 1. When the manual calls for "c7 x 12 x 80" I'm assuming that means 12 mm id & 80mm length - what's c7? 2. Got some clamps from busdepot.com. They are right on. Sorry, this wasn't a question. 3. Who has the better prices on proper lines, per my demands? Doesn't matter all that much because I'll do what it takes. 4. Does anyone have a list of all the items needed to redo the rubber fuel hoses, particularly for a pre-83 car? Don't care about vacuum lines - have a ton of all diam's & colors. Primarily looking to keep fuel leaks at bay. 5. Who can I "donate" 4 gallons of laquered fuel to? 6. Injectors - what does it take to rebuild them. Mine seem to be just fine, but they are 35 years old - lotsa crap has to have gotten to the screens. All positive/negative responses considered. Negative responses will probably be ignored, but post what you like. Pat |

C7 x 12 means the ID is 7mm and the OD is 12mm. This gives a wall thickness of 2.5mm, and is the dimension of the original fabric-covered fuel lines. The newer ones, non-fabric covered, are 7 x 13, giving a wall thickness of 3mm. The 7 x 13 can handle higher fuel pressures, which may or may not be that critical with D-Jet. I think the key was the elimination of the fabric, which could become saturated with moisture (or battery acid below the battery), keeping the rubber damp, and leading to early failure.
The later non-fabric 7x13 IS factory, at least in the engine compartment, as of the recall. Even though no car left the factory with it. The clamps for the 7 x 12 will NOT fit the later lines, but the later 13mm clamps will close down enough to fit the earlier 12mm lines. If you're looking for dead-nuts originality, be sure your bus depot clamps are 12mm. |

Exact degree of plating as my new distributor rails too! Gonna work & look great! |
