Default 940 Turbo rubber fuel line under car

The short section between the hardline from the tank area and the pump inlet; what size hose is that and where can I get it? Every store around here only has 5/16" and 3/8" and this seems much bigger. On my car it has a barbed fitting halfway down with a schrader valve. Anyway after 26 years its soft and leaking and I'd like to replace with something rated for gasoline.

Default fuel line

When I had the same issue I found Goodyear half-inch fuel-rated hose at my auto parts store, worked fine. Rated 35psi which is ok in that location.

If you can get it, go for the highest PSI rated fuel line you can find. I’ve read too many stories of appropriate PSI rating failing. Not something to leave to chance.

I buy the correct fuel hose in bulk, it's a metric sized hose. I'll PM you later. I'll go measure the length from one of my cars as well.

For a genuine Volvo part. Tasca Volvo had a very reasonable price for a meter length section of that hose. It's 12mm ID metric hose. If you have a truck parts supplier near you. They will carry the 1/2" hose that is higher rated and works.

I recently had that same hose fail again on my 88 765. I went to NAPA to get a 12 inch length of 1/2 inch fuel hose. When I removed the leaking hose I found that it had same markings as my new hose. But it was rated for emissions. Yesterday I went back to NAPA and asked for red hose. This is what I got for $4.44 per foot:

Gates Plant Master Xtreme 325 Braid 1/2" [12.5]. It has black Viton inner tube, synthetic braid, and red Viton outer. And no, the 12.5 mm is not a typo. This hose is listed as MULTI-DUTY HOSE part number MSH H-1706

The OE spec hose used on the 9 series, leaving the in tank pump and heading toward the chassis pump, is NOT an inch spec hose. I found the PN by searching TASCAparts.com and ended up buying a meter from a Volvo Dealer in AZ. It is darn close to a 7/16" hose, and I've heard tell of some folks buying a truck sized fuel line to replace it. I know for certain it wasn't 3/8 or 5/16 (which are used in the engine bay on the fuel supply & return hoses connected to the engine). I know the 1 meter length was enough hose to do both of my 92 vehicles.

Looks as though the OE size comes closest to 15/32 inch. I've seen this size as OE on Fords. Good luck finding it locally.
