i checked out the fuel injector replacement hose kit on fast lane... its 20 bux to do 2 injectors. But the price seems steep for two short pieces of hose and 4 clamps. Do i need to use that specific item, or will the proper sized fuel line hose work also? i didnt know if i needed a special kind of hose or not... any info on this would be great, and seeing as i have probably 3000 dollars worth of body work to do, i would like to save as much money as possible when i am able to.

Also, if regular fuel hose will work, what size hose is it, so i can pick some up before i take the car all apart...

I did this last August using four of the kits, which, I do believe, were a bit cheaper then.

As I understand it, the critical factors are: 1) using fuel injection line, not regular old gas line -- a fuel injected system functions at a much greater pressure then does a non-injected system; 2) the type of clamps (not regular hose clamps that cinch down by drawing on the slots in the clamp) are important too because FI clamps actually equalize the pressure around the line.

With this said, I am certain you can cobble together the appropriate parts and probably save 50% or more.

You will most assuredly receive additional info and comments from the techno-folks here.

so is the general concensus that i should just spend the 20 bux per set of injectors to replace them? or is there an alternate way? i know someone knows this...

If you carefully cut the crimped metal off from around the hose, the hose just slips onto a barb really. Is what I did with my friend's car was that then I used FI hose and come clamps from NAPA that look like the MB clamps, not the ones with the slots in them. If you go the route that I explained it will be very cheap to replace the hoses. I learned the trick from an MB tech and the car hasn't roasted yet.

Thanks

You don't need those kits. I bought a 10' section of FI hi pressure 5/16" hose which worked fine and used stock clamps for it. While you are at it you might as well replace all of the hose which connects the fuel rails and lines, there are 5-6 pieces there too. The hose cost about $3 a foot and I still have several feet left so you could probably get away with 5', in fact if you want I can see what I have left and can sell you the rest for what I paid per foot if you like.

For $20, you can buy plenty of high-pressure 5/16" injector hose and new clamps, and do it yourself, and replace all the fuel hose under the hood.

While you're in there, consider redoing the injector seals. Mine were really dried out, brittle, and mis-shapen. Dunno if they really have much impact on the FI performance though.

When I did mine I found a dremmel or equivalent with a cutting disk the best way of getting the old crimped clamps off the injectors once they were out of the car. When you put the replacement hose clamps on don't tighten them all the way up, leave about 1 or 2 mm gap on the clamp thread. You should also replace the injector rubber rings as well while you are at it as they harden over time and can cause a vacumm leak.

Yeah, cuttin off the crimped clamps was a bit of a challenge. I too used a dremel.

I had posted elsewhere that when I did my injector hose replacement I hadn't ordered seals and when I got it apart I realized mine were bad and it was the weekend and no parts stores had any replacements. So, falling back on "necessity is the mother of invention" I realized that if I cut the FI hose into short pieces, about the thickness of the seals that the ID was just right to fit tightly on the end of the injectors and the OD fit snugly in the intake manifold. I figured, at least temporarily this would allow me to get the car back up and running and, in fact, I never replaced them as the car ran fine with no noticeable vacuum leaks. So, I thought I would pass along this tip again.
