I just received an estimate of $1,300 for replacement of the fuel lines on my '95 Integra GSR.

Does this seem excessive? They estimated 16 hours of labor... the need to drop the fuel tank, and the need to remove the power steering pump.

Some things I'm wondering about:
1. Is the high pressure fuel line a single pipe all the way from the pump to the fuel filter?

2. Same question for the evap line.

3. A week before I started noticing the smell of leaking gas, I drove over a seemingly low snowbank at the end of my driveway, but heard and felt striking the underside of the vehicle. Could this have resulted in a broken fuel line in the section where the lines rise up into the engine compartment?

Thanks... I appreciate any insight anyone can provide.
