Anyone have experience fixing a fuel leak? I left my car sitting in my garage for 5 months without fuel stabilizer, pretty sure it ate through at least one line.

Do I need to replace the entire rail (4 lines), or is there a better method?

 

Bummer. Never heard of fuel eating through hard lines.

 

I find it hard to believe fuel did that. if it did you need to inspect the inside of the fuel tank as well

 

Your lines are very rusty, look to me like the rust got so far in that it developed a pin size hole, I've lost a clutch line and PS line like that in my other cars.

Your best bet is probably source some used line in the classified section, or ping Fritz.

 

i didn't look, but Mazda usually sells these individually, cost is usually fairly reasonable

 

def leaking a lot. The rails are dry except for a foot on each side of the drip, so I'm assuming it's coming from this area. Can I just replace part of the rail?

 

the main fuel line is FD01-45-111 the return is FD01-45-611A. they both retail around $64. Mazda USA has plenty of each.

the 3rd pipe is the fuel vapor pipe, FD01-45-711 its $51

and the 4th pipe is the rear brake pipe, FD01-45-360B its $37.50, but NLA, so there are only the 7 left in the world

 

Thanks! I'm going to order the 2 pipes and just replace them myself (hopefully). I believe the return I want is 611 though, not 611A.

 

Not familiar with this particular part, but in general a letter suffix on a Mazda part number usually indicates an upgrade that is compatible with the basic part.

 

correct, the de-code is 45-611, the part number is FD01-45-611A
