Thanks for all the help with the CB550 Tank question I posted awhile back. things here have kinda gotten back to normal ( whatever that is ). I ended up putting a tank from a 1975 CB750K on my CB550. Only had to trim about half an inch from the seat pan, no sweat !. The question is about petcock clearance, The petcock is an aftermarket chrome one from eBay. It is about 3/4 inch from the valve cover, is there going to be an issue over heat ? Seems kinda close to me, but I am far from being an expert !. Opinions ?. Thanks for your time

John

If the gas lin is actually touching a hot part of the engine, I would try to get one of those spring looking things to slide over the hose to keep it from actually touching the metal.

so you want to put metal against the the hot metal so the the heat proof rubber hose is not touching hot metal<img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_big.gif border=0 align=middle><img src=icon_smile_tongue.gif border=0 align=middle>

Squeak, maybe I am wrong, but I couple of my bikes were set up like that.....you know, maybe it was to keep the kinks out,or maybe they were pre high temperature rubber. Heck, I DID think it was a good idea........

the metal clamp will conduct the heat almost as well as having the rubber againts the engine. it was most likely there to prevent rubbing (abrasion)

3/4 Inch seems like enough clearance as long as you are not risking the fuel line actually touching the valve covers.

Fuel lines clear quite well, was just concerned about a hot petcock ( that didnt sound right )

Sounds like your gas tank is the least of your problems.

Damn man... I have seen some folks set themselves up... but you just took the cake on that one.
