1987 caprice classic fuel line question

[moif]

I have a fuel leak that`s running from the top of the tank down the front of the tank and along the bottom thus dripping on the ground. I`m wondering if there`s a rubber flex line on top of the tank (can`t see) that may be leaking or is it a metal line from tank to engine. I always keep my tank topped off.

There are rubber hoses that connect the steel lines with the pickup lines on the top of the tank. Plus, there is an O-ring at the top of the pickup assembly that might be leaking.

usually the return line 5/16 inch size is the leaker...the tank should be dropped and the bad section cut out and replaced...use of a gas line hose with double clamps on each end should work...you may need to go the the scrap yard to get other parts, if needed....


metal ines come off the tank top where I believe on your vehicle the gas line rubber hoses are connected ,,,then after 2 feet or so the metal lines take over..to the engine compartment..

I forgot to mention topping off the fuel tank and parking the vehicle is a NO NO...

you will in a very short time damage the fuel evap system....
