For those that have 944's and in particular the Pre 85.5's the fuel line from the tank to the pump is in the shape of an elongated S. Or a better description would be a strait piece with two bends on the ends that are about 270 deg bends. The fuel line is 1/2" id. Porsche actually sells this piece (it has a part number on it) But it is $20 plus shipping and I have several feet of 1/2 inch fuel line left over from a previous project.
I was actually thinking of using some copper tubing and inserting it into the line and then bending it. Yes this would put a bit of a restriction into the line but I don't think it would be enough to hurt things. The other option is to just purchased a couple of 90 deg fittings and piece together something. However this would require a bunch of hose clamps and I would probably end up spending more than the $20 for the part. The last option is the bend up a replacement from soft steel or copper line flair the ends and then add two small bit soft hose to connect it to the tank and the pump. I have the bending tools and the flaring kit so this is easy however I am not sure I want a sold line running form the tank to the pump. The pump has quite a significant isolation system of rubber mounts on it and thus I suspect it vibrates quire a bit. I am not sure vibrating a steel line that much is a good thing.
SO. After explaining all this my question is there a way to bend tight radius's in to fuel line and have it keep the bend while not collapsing the line? I could make a jig out of screws/wood to retain the line and then heat it / bake it. I have several 1800 deg thermal plastic hot air welding guns that I can make a nice little oven by building a box out of pieces of foil faced polyisocyanurate insulation and then use the hot air welders to heat the contents of the box. Anyone else have any ideas?
