Default Replacing fuel line?

Just received my new S/S pump-to-carb fuel line from "Classic Tube" . Wondering if there are any road-blocks I'll run into trying to replace old with new. Does anything have to be removed for access?

As I remember, you'll have to figure out a way to keep the gas from getting all over the place. Not just from the carb, but from the tank - it runs downhill and just keeps coming and coming...

Better have a set of flare wrentches to do the job right without tearing up the fittings. See Sears or ask local Napa store
GoodLuck

As others have said...
Definately use Flare Wrenches.
Also use a pair of vice grips with duct tape around the grooves in the jaws as not to damage the flex hose from your hard line to the pump

I have flare wrenches. What is this "flex hose" you speak of? My (stock) fuel line is solid, from pump to carb.

SkunkApe,
I just replaced my bubba rubba line. Pre-route the new line from underneath. It's kinda tough, but you can do it. Use a flare nut wrench to loosen old line at the pump. Mine was over tightened and was a bear. Even the flare nut wrench stripped the nut. I was finally able to lock on to it with a pair of vise grips to get it loose. Just loosen it until it starts leaking, then hand tighten till it stops. Then get the new one ready, quickly take the old one off, put the new one in, and just tighten it until it stops leaking. Now go up top and put that one in. It should be aligned close enough to hand tighten the line fitting to the larger carb fitting. Be careful here...it's easy to strip the threads on the fittings. Make sure they turn easily by hand, then tighten with a flare nut wrench. After getting the top in place, go back to the pump end and tighten. I had a small amount of fuel run down my arm while doing it. I heard that you can pinch the fuel line with something to slow the flow, but if you're quick you can do it with little leakage. Start the car to check for leaks...some folks have trouble with the carb connections leaking and the first reaction is to tighten it more. Be careful...I know from experience. I thought that by taking the larger carb fittling out to start the threads would make it all go together easier. Instead, the pressure on the line forced the threads to strip. Yikes! Carb teardown and ship to Cleveland, OH...painful!
Good luck and let us know how it goes.

Make sure there is an air gap between the fuel line and the engine block. Otherwise your fuel will heat up and percolate in the carb. If this happens you can either insulate the fuel line or get one that bends correctly.

Thanks all for the tips. I'm glad to hear I don't hafta remove anything to get this done.

Mmmm....I love the smell of gasoline after it has run down my arm and saturated my armpit. Smells better than any deodorant...
