After searching, researching, and lots of reading:

Fuel smell is coming from the fuel rail after running the engine for a short time.

Step one is to replace fuel injector seals, o-rings, etc. Volvo dealership sells a "kit" for about $4 that has all o-rings, the little plastic cap over sprayer, the connector bumpers, etc.

My question is regarding the short rubber hose running from one of the hard lines to the fuel pressure regulator. It has become very hard and brittle, and is showing stress cracks ( ). Can I simply use a small peice of fuel-safe hose with new clamps to replace this? Or does it need to be the OEM part? My main concern is with the 40-45 PSI of fuel pressure in that area.

I'm trying to eliminate the possiblity of a failed and leaking fuel pressure regulator, as that is a $100 fix. I'm told those typically don't go bad.

Car is a '95 with almost 100k for those that might ask...

If pics are needed, ask.

Well, i'm not exactly sure what piece your talking about... too lazy to look at 1:20 in the morning but... I can assure you that good old NAPA quality fuel hose can easily handle 40-50 psi. And that could very well be your culprit... The only thing you will have to be careful of is the clamps. Dont over tighten anything fragile in the area, but make sure you get a good seal and you should be fine.

Aye, that's what I figured. If you look at your fuel rail, you'll see it. No need to remove the cover. I'll head to NAPA and get some hose and clamps. Online would be stupid since it's about 3" of hose, and most places sell enough footage to go from the fuel tank to the injectors.

I know I keep about 1-2 ft. of fuel hose around just in case. It's always nice to have around for emergencies... But, thats just me.

avoid standard fuel line, make sure it's the tougher (and significantly more expensive) fuel INJECTION line.

standard fuel hose will hold 40 psi no problem, but that's a lot closer to it's limit and it will wear out/fail a lot sooner than the injection line.

You can actually get that super tough fuel injection line at Lowe's for around $1/ft. Much different than standard fuel line.

I'll do a little shopping this weekend, and hopefully have a write-up done for it by Sunday.

So fuel injection line would be the stuff with the cross-threading between the plys of rubber?

Okie doke... here we go:

2 feet of Fuel Injection hose from AutoZone - $9

1 Box of fuel line clamps - $5

The old hose was a PITA to get off; it was brittle and stuck on there like a beast! I replaced with a small length of the new hose, put on new re-useable clamps. Voi-la! Strong smell of fuel is GONE baby, GONE!!

The old hose was really messed up, and am I ever releived to see no signs of leakage from the pressure regulator. I bought more hose to fix it when it dries up and cracks again; happens fast in the Arizona heat.
