In the refurbishing of the engine bay, I began wondering about the clamps on the fuel lines. The originals, as I recall, were what I call "tension" clamps, sort of "spring loaded" by virue of their shape. I have something similar on my old motorcycle fuel petcock. What they have been replaced with over the years are the typical screwdriver-tightened "hose clamp". The P+A dealer sez the hose clamp is definitely better as they can be "tightened" and don't loose "tension" like the OEM do/did. I don't ever remember the originals getting "weak", as I remember it, they were a nuisance to get off in the first place because they were both so tight, and awkward to access to release the tension they held on the hose.
I'm assuming that the old syle clamps can still be gotten somewhere. I know what's original here, I'm wondering what's better. |

Hate to put pressure on you, but remember it's not original unless you use them. I think they may still be available from the Porsche dealer. Between you & me I would upgrade to a safety/practical installation with fuel lines, (my opinion). Tom Attached thumbnail(s) ![]() |

Tom Tom, I think what Paul is referring to are the clamps used to mount the fuel lines to the injectors. I say this because your pic is that of the clamps that hold the lines in place. The original clamps that sealed the rubber/cloth fuel ine to the injectors was a crimp-on type claamp - not adjustable. On my 914, these were replaced with screw compression clamps when Porsche did the fuel line recall ('74?). They still work prefectly today & are very small. Wish I could show a picture, but it's 28 degrees in my garage (5 degrees outside) & I'm a sissy. Pat |
