SS Fuel Line Replacement Options

[jks1981]

Hello,
I recently bought my first 914, and within a couple of weeks, gas was pouring out the bottom of it. The previous owner had rubber fuel hose running from the gas tank to the fuel pump in the engine compartment (carbed car). This line had cracked where it exited the firewall under the enginer compartment.

So I am going to replace the tunnel line with stainless, keeping in mind this car is now carbed, does it matter if I use 9.5 or 8mm? Also, where the fuel line exits under the engine compartment, is it best to just connect up some hose to run into the compartment, or is there a better way? It seems the lines are pretty exposed there.

Thanks!
James

There are quality vendors out there who will do well by you. If you are more DIY inclined JEGs and Summit sell SS high pressure hose (in english sizes). You can get silver bearing brazing rod and add whatever fitting you want by pushing the fitting on and the brazing with map gas or acetylene. Of course then it is permanently on the car.

This will open a can of worms but, with a Carb set up you only need to run one line from the Tank to the engine, you don't need the return line with a carb set up. Also you don't need 20-30 lbs of pressure with Carbs, mine works fine with around 3 lbs and you're less likely to blow a hose connection off. I had mine installed at the shop that did my engine rebuild while the engine was out and he ran stainless threw the tunnel and fire wall bushing into the engine compartment, then to ethanol proof hose to the carb. I don't think the diameter of the steel line we make much difference with your set up.
