Re: 1999 Volvo s80 fuel line leak before and after the...
This perticular solution requires special fuel line tools to disconect the clips on the line. I would first locate the leak and determine if the entire fuel line is at fault or if it is just a connection. most commonly a piece of the line has deterieated and cracked and can be readily replaced with an OE part from a local parts house. a fuel line disconect for your vehicle can be gotten at the same parts place in most cases. Just ask the counter person what disconect it takes.

The rear seat (the lower part) will pop out easily. Grab under the front edge of the seat and give it a firm tug upwards. It will pop out. Make sure you remove all the spare change before re-assembly. The upper part (the back rest) is a little more involved.
First, check the fuel rail and make sure it is building pressure. Take the cap off the nipple (it looks and works like a tire pressure valve stem). If no pressure, first make sure a clogged fuel filter isn\'t the problem. The fuel pump is accessed under the back seat if you\'re not getting fuel to the filter. If that doesn\'t solve the problem, give me more info as to what you have done and when the problem started.
the first thing is to try another key, you may have a bad chip in that key, this dissables the fuel pump, try that first, next would be to test for power at the pump, if theres power and a good ground at pump then you need a fuelpump, you can get to pump by removing rear seat then remove the cover on the floor and you will see pump and wiring good luck.
The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. Note arrow on filter for correct fuel flow. Good luck and hope this helps and no smoking please LOL

This should be repairable from the top. Pull out the rear seat cushion and remove the two black round access covers to access the fuel pump covers. The seals for these covers tend to leak and if they are leaking, you will see it when the covers are off.
It's very easy. Just take off the back seat behind the driver. There is a cover , remove it and then you have it. Be carefull ther is a big plastic nut and all is under it - regular right hand thread. Change the o-ring before puting it back.
