Like a lot of fuel injected engines, mine is a bit of a challenge to start hot (IO 540K). The other day I had occasion to take the top cowl off while the engine was quite hot and even with a purge valve and a considerable period on the electric fuel pump, 3 or 4 of the spider lines were very hot.
Got me to wondering if sleeving them with a suitable insulator would be a good idea. Since the famed TS of TSF is building his RV-7 in my hanger (helped him with his flap enclosure and floor boards this weekend), I asked him if he had a solution. He said he'd look into it and already has a sample or two coming for us to examine.
I can't do much on it until November because I'm leaving the country for a month to do some motorcycle riding in Italy this weekend, but I thought I'd best ask if anyone has ever done anything like this and what the results were. Since I've never seen an engine with fire sleeved spider lines, I'm guessing there may be reasons not to do it, but honestly I don't know.
Any ideas?
