I need a replacement petcock for my 1980 GS550ET . I have not been successful in finding a replacement other than from Suzuki ($) . The problem is the petcock mounting location on this fuel tank requires the fuel nipple and vacuum nipple to face forward and most all face to the rear. The petcock is located to the rear of the tank while most other models locate petcock to mid 3rd of the tank. The vacuum nipple can be rotated to the front but the fuel nipple cannot which causes the fuel line to be 'crimped' . The only petcock I have found that will work has the 50mm bold spacing and mine is 44mm. I can mount up the petcock from my '85 GS1150EF , BUT fuel nipple faces the rear. I can't find a rebuild kit for this petcock either, it has the larger diaphragm too . I have thought about trying to mount a 90 degree fuel line fitting but just not very much room under there. The petcock sits almost on top of the factory 32mm CV's . Any insight you can lend is much appreciated.
