It's common for some air to appear at the top of a translucent plastic fuel filter. When you squeeze your primer bulb, this should change--squeezing the bulb will force more air into the filter at first, but then less and less will appear each time the gas level 'rebounds'. The carb on your engine does not draw from the very top of the filter; the feed for the fuel line outbound is usually deep inside than it looks.

You have been given a good answer regarding a "visual, or "clear" fuel filter and yes as stated, there is usually some air trapped on the "up" or highest" point of the filter. But once running has been established, there should be no visible air bubbles seen traveling in the fuel in the fuel line. Now once again, there may still exist a bubble in the clear filter. In most cases the fuel lines are nontransparent. But even on Race boats when the engine is running sporadically, I will often install a short piece of clear line in the fuel line to see if the fuel pickup inside the fuel tank has developed a leak. Also the fittings on the fuel tank itself are mostly made of aluminum and these fittings are subject to leaking. Aluminum fittings (of this grade, not SAE or AN type) are not well suited to the vibrations associated with boating, as they are constructed of the cheap grades of aluminum.
not sure how long ago this was posted! 32 is a egr circuit code on fuel injected models. it is a baro circuit code on carburated models. 33 is a high voltage detected with the map sensor!
He Injected red paint into them. But that only created another problem: Red baby syndrome
Assuming its Fuel injected. check the FUEL pump, or the fuel pump relay. there is also a fuel pump fuse under the hood you might check that first. Your problem is most likely a bad fuel pump. If its carburated check the fuel pump or a plugged fuel filer.
It doesn't have a carburetor, it is fuel injected. What seems to be the problem?
about $100-200 if running (Getting parts will be the problem w/ that motor).
It sounds like a transmission problem rather than an engine problem.
Some 250 bikes are not fuel injected. I am storing my cousins 250 ninja and I have the same problem. Come to find out, not fuel injected.
Cause' if the fuel combusted in the fuel line, you'd have a major problem.
The most likely cause is that it is idling to fast. Try adjusting it down. Then set the timing to the proper specifications and readjust the idle speed. Another thing could be a vacuum leak or a float or fuel level problem.
My mechanic says 100:1 I have done this for 40l last season without a problem
if its carburated you can adjust it it that's probably not the problem but try it any way. couple words for you electronic valve in the carb.....
93 Chev Cheyenne is Throttle Body injected and computer controlled. There is no air-fuel mixture screw and no carburater, just the throttle body. If you suspect an air-fuel mixture problem may I suggest that you run a computer diagnostic test. If either the EGR valve or Oxygen sensor are not functioning properly you can have problems that are similar to air-fuel mixture problems of carburated engines. There may also be other situations that cause that problem but you won't know until you run a diagnostic test.
