Any suggestions as to where I can fine new fuel / vacuum lines for 54 COE 5700?

Hi Danny, 1st off, I separated out your post because you had piggybacked on someone else's thread (please create your own thread, especially when changing topics). Also, that thread was 12 years old! (Kudos for searching though and finding some info from that far back!)

I am assuming you are referring to hard lines, and not just the rubber hose. I think you are going to probably have to get tubing and bend it, unless you are looking for some used stuff. If you are actually looking for used, there is a parts wanted section that you need to post in. (all buying and selling goes on in the swap meet section).

Hy DannyZ, welcome, could you please tell us from where to where you need the lines to go and what function they will be performing?

Finding pre-bent lines for a cabover is probably going to be a lost cause. If you have the originals in somewhat intact condition, even if they're kinked or rusty, the best bet will probably be to use them as a pattern to bend up new lines from straight tubing. If not, just use a bit of logic about things- - - -the lines won't care if they're routed a little differently than original, as long as the fuel and vacuum gets to where it needs to be. Try not to route the fuel line over the top of the valve cover or too close to the exhaust manifold etc. because engine compartment heat in a COE can get pretty intense and contribute to fuel boiling in the lines, commonly called "vapor lock".

The copper/nickel metal lines are much easier to work with (usually no tubing bender needed) and resist corrosion better than steel lines. Don't ask for "Cunifer" a you will pay double just for the name. There isn't man or gun big enough to force me to ever use stainless steel lines again. As Jerry stated: route them away from heat and interference and the routing you choose makes no difference in the function.

Agree with Coilover on the advantages of copper/nickel lines. I would disagree, however, about his comments on the Cunifer brand, which is the original British manufacturer that provides for European cars. I compared the weight of a 25 foot roll of copper/nickel 1/4 inch line purchased from NAPA with the same thing in the Cunifer brand. The NAPA line weighed 40% less than Cunifer, the difference derived from the thickness of the tube wall. Now, I am not saying that the NAPA line is dangerous but any cost savings based on tube wall thickness is not right in my opinion.

How thin does a line have to be to be dangerous when fuel pressure of 3-5 PSI is involved, and/or 1/2 atmosphere of vacuum? Brake line pressure is another matter entirely, but even then, I can't imagine a company making something available for sale that approaches its limits of pressure in normal use. Thar's an open invitation to ambulance chasers to "Sue Me!"

I realize that this is an advertisement but see the bottom of the home page;
fedhillusa.com

Is a thinner gas line more prone to crack? Out of spec for a brake line but does it matter on my COE with hydrovac? A few more dollars gets you the real thing, not a Chinese knock off. As I said, I have no idea whether the thinner product is safe but for me it is an easy choice.
