I'm trying to replace my fuel filter on my 97 Ouback Legacy and the **##@@ rubber hose seems almost welded to the old inlet and outlet tubes. I want to buy some new fuel hose without first removing the old hose to compare it. (I temporarily have just one car) The local Subaru dealer couldn't give me the diameter b/c his "book" just lists individual hose sections, rather than bulk hose. (And he doesn't have the required section in stock anyway).

I have a Haynes book, but I didn't see the hose diamater listed in it. Can I just buy a length of some generic fuel hose at an auto supply store? I've never had so much trouble over changing a fuel filter.

I had exactly the same problem

Take a piece of hose to any auto parts store and buy ennough to replace both the lines that feed the filter. Also buy new hose clamps.

I also put silicone grease over the filter's nipples to make it easy to change out the next time.

I went out to my 97 OB to take a look, but there is no size marked on the hoses, just a number. I know that my dealer changed them the last time they changed the filter. Looks to be about 1/4", but I'm not great at judging hose size.

Easiest thing is to cut the hoses off, but you can "work" them off if you really want to. Sometimes by twisting, or by slipping something small and pointy under the end to loosen them. (Several times, working around the hose.) Either way, you usually end up damaging the hose.

You only need about 2 feet by the looks of it. You could pick that up in bulk in about about 3 sizes (just to be sure) if you are really desperate. My dealer changed the other hoses too as I recall (fuel rail, fuel return?) the last time. Not sure if they are all the same size.

easiest way to find the size is to take the new fuel filter to the store where you are buying hose. just try them on the new filter until you find your match.

another trick you can try to remove the fuel hose is to use a pair of needle nose pliers that are bent (either 45 or 90 deg). loosely put them around the metal portion of the line, and use them to push the hose off. when you pull on the line, it has a tendancy to act like chinese fingercuffs, grabbing the filter more tightly.

Thanks everyone; I followed Commuter's idea and bought some hose in two different sizes, 1/4 in. and 3/8 in. I know its one of those two.
