I have a 1997 Buick Park Avenue Ultra that has a gas leak in a plastic fuel line between the metal line in the engine compartment. I would like to find out the pressure that these lines run at so that I may replace them. I am planning to replace the bad section with reinforced high pressure rubber fuel line and hose clamps. However, I need to know how high pressure the rubber line needs to be.

You will find a gas line repair kit at NAPA auto stores for these fuel lines ( Most Auto. parts stores may have these as well ) the repair kits are metal lines that insert into the broken fuel hose , you can not repair these lines with a rubber hose and clamp they will leak .HTH

The kit is a metal line that inserts into the hard plastic line and you clamp . Go look at the kit and read the instructions it will help you choose what you want to do.
The kit is the only safe way to repair these lines that I have seen short of replacing the complete line from GM.

clarifications.....
Thank you for the information from both of you. I have not yet been able to personally see these fix kits, but, the O.E.M. GM design seems to be very poor. The hard plastic line is doomed to harden from the continued exposure to the heat trapped under the engine cover that prettifies the engine. It is supposed to flex with the movement of the motor and once it gets too crispy it leaks. The previous owner of this car said that he had the exact same line replaced about 4 yrs ago. He replaced it with the O.E.M. GM part at that time. it seems to me that using a stainless fuel line to cover the distance between the motor and the firewall while using 60psi reinforced rubber fuel line and double clamps on both sides of a double flared stainless line ends at the joints would be far superior for both longevity and replacement.
I am going to order the O.E.M. part from GM, but if this happens again while I own the car I may try a different route.
