fixing metal fuel lines

bluejeepkid · Jan 10, 2013

Anything wrong with using a section of rubber fuel line to repair a damaged metal fuel line? I would essentially be splicing in a short section of rubber fuel hose into the metal fuel line.

Be sure to use fuel rated hose. Temporary fix IMHO.

Put a half-arsed flare on each end of the metal line to give the hoseclamps something to bite against if the hose tries to slide off, use fuel injection rated hose, and full circle fuel injection rated clamps. Make sure to not flare the tube too much to get the hose over it, if you have to force it it's too much and it'll dig up the inside of the hose.

And make sure it is fuel injector hose, 50 psi rated. Old style fuel hose will not handle the pressure.

What are these?

These: http://www.amazon.com/AAS-Fuel-Injection-Clamps-FI6/dp/B0040CU0HM

Instead of normal hose clamps or spring clamps.

Make sure you get the right size - iirc, those lines are 3/8" OD, so you want 3/8" ID fuel injection hose and fuel injection hoseclamps listed for 3/8" ID fuel injection hose.

Regular hose clamps don't put full inward pressure on every section of the hose under them - they have a loose spot under each side of the screw housing, usually. That's fine for cooling systems and the like but when you get to higher pressures, they can start to leak.

Better fix... Get a short section of metal line and use compression fittings on both ends. Better then rubber line by a long shot. Will hold the pressure with no issue.

Even better fix: Purchase an OEM fuel line from the dealer.

A cobbled together fuel line is dangerous.

Yes, better, but IMHO, still not a permanent fix.

The RIGHT way, and permanent.:thumbup:

No need to mess with it twice.

x2. Do it right with a new line. Fuel lines are no place to "fix".
