dcntma750 Posted March 30, 2020 Share Posted March 30, 2020 HI I HAVE ON A FEW FORUMS AND TO NO AVAIL,,, im trying to get someone with same bike as mine and lift up tank and snap a pic, cause i got 4 hoses not counting the one with nipple on top of carb #4 but in the pic hoses 1&2 are for fuel ,, now my petcock doesnt have a vacuum and fuel line it has 2 fuel lines and im running 2 separate air filters no airbox so where do the other lines #3#4#5?

Captain Chaos Posted March 30, 2020 Share Posted March 30, 2020 Hi and welcome to group therapy. A small introduction in the general section is appreciated. hoses 3 & 4 are breathers, they should be left open, pointing down behind the air filters. 5 looks like a vacuum hose. One end goes to the carb top/intake rubber #4, the other end should be blocked off if it's not connected to the fuel tap. Quote Link to comment
Dezza Posted March 30, 2020 Share Posted March 30, 2020 You have an aftermarket fuel tap (Pingel) , which does not require a vacuum take off. The spigot on the carbs thus has to be blanked. Quote Link to comment
60Greyhound Posted March 30, 2020 Share Posted March 30, 2020 sorry to jump on this... was going to ask the same question. Can I check that 1&2 on the pic go to the bottom fittings and are fuel inlet. 3&4 are the top fittings and are just a breather? I also have what looks like a large breather in the centre of mine, near the throttle cable - should this connect to anything? I believe I have the bst38ss carbs. Quote Link to comment
dcntma750 Posted March 30, 2020 Author Share Posted March 30, 2020 thanks really appreciate the help but it will only run for a short period when choke is on but if i connect both breather hoses to a t and blow in it it runs ? and i just dont feel like riding around with a tube in my mouth,, any ideas?

dcntma750 Posted March 30, 2020 Author Share Posted March 30, 2020 What pulls the gas through? Should be some kind of vacuum no? Since it has no fuel pump Quote Link to comment

Since it has no fuel pump Nothing pulls it through. Pingle are a gravity tap. Like running a diaphragm (vaccuum) tap on prime. Fuel falls under its own weight. Quote Link to comment
