Fuel line Question, Replace hard line in tunnel with soft??? Options

[kfish914]

I know I may get a lashing for asking this but with a budget in mind. Would there be any issues with replacing the hard plastic lines with rubber lines? I know I could use electrician's fish tape to pull it through into place. My worries are the grommet area (where the hose would pass through the body panels) rubbing or kinking the fuel line. I am exchanging the current 1.8 four, for a 2.7 six.
Any thoughts?

Really, i mean by the time you buy enough FI hose to do the job, you could buy steel lines, dinner, a movie or a hooker a female companion for the night.

Really? $98.00 for a pair of SS lines. For High pressure systems add fittings at $48.00 and you get $146.00 to save purchasing an extra 5 feet of fuel line. The cost of 5 feet of extra fuel line going through the tunnel wouldn't get you a hand job with even the cheapest hooker. (IMG:style_emoticons/default/lol-2.gif)

In addition, the flares on the metal lines leave something to be desired for a high pressure system and puts a joint between that flare and rubber both front and rear (X2) and in the hottest part of the car where a failure would blow fuel all over hot headers and engine. That would concern me a lot more than a one piece fuel line running front to rear but runs through the tunnel.

Many cars have hidden rubber fuel line. Look at many cars on the top of the fuel tank. If you work on cars, most leaks show up at the joints, especially at the clamps.

So you have a choices...

1. Replace the lines with a one piece FI line and live with a line through the cab
2. Use metal through the cab and live with twice the connections

It's all about your comfort level......

Probably the best compromise is steel lines with FI fittings silver soldered on the ends so that a mechanical connection can be made but that makes getting them through the chassis difficult.
