Tired of those generic BLACK fuel lines? Silicon hoses would look nice, but won't stand up to gasoline. SO, the fuel injection hoses on the Z32 have an outside diameter of 5/8". Go on ebay and look up 1 1/4" 2 to 1 shrink tubing. There are several different colors to match your engine/under the hood color scheme. You can get several different continuous lengths so your install will be 1 piece per hose (cut to length). You need about 5' to do all your hoses. Best way to shrink tubing is with a heat gun. Disclaimer: this is just off the cuff. I haven't tried this in a real life application. I don't know if shrink tubing will hold up to under hood temps, but I have applied to the hoses I intend to use on my next engine and it LOOKS good. Why bother? If you have to ask, this is not for you>
