If your petcock is an OEM unit, all the gaskets will be the same regardless of what type tank it is. If it were mine, I'd replace the vacuum operated petcock with a high quality manually operated petcock like a Pingle. The reason for this is exactly what you're experiencing right now. The diaphragm in the back of the petcock gets a small hole in it and starts to leak fuel or worse yet, won't open and allow fuel to flow from the tank to the carb. They are notorious for this. I've seen too many riders with a full tank of fuel but not drop in the carb. Spring for a Pingle petcock and the problems are over for a very long time.

Good luck

Yes or a small bypass hose. You may be able to get a loan of a tester at autozone, oreilys, or advance autoparts. You want a radiator pressure tester. Do not exceed the cap rated pressure. When the engine is warm, you can add pressure and look for water seepage.

There are also chemicals to add to detect leaks if the first method is unsuccessful.

Where is the transmission oil serviced

Run the Low Rider's motor for a few minutes to warm the oil up. Shut off the bike.
  • 2 Find your Low Rider's drain plug (on the oil pan). Using the screwdriver, loosen then remove the drain plug, and drain the oil into the drain pan.
  • 3 Remove the Low Rider's dipstick.
  • 4 Let the oil drain completely.
  • 5 Clean the drain plug threads with a clean cloth or paper towel, apply sealant, and replace the oil plug and dipstick.
  • 6 Move the drain pan to beneath the oil filter. Using the oil filter wrench, remove the oil filter.
  • 7 Discard the filter in the pan with the old oil. It is full of oil.
  • 8 With a clean rag or paper towel, clean the area where the gasket meets the motor.
  • 9 With a clean finger, rub a bit of new oil on the gasket of the new oil filter before installing it.
  • 10 Install the new filter, turning until snug, then turn it by hand another 1/2 turn. Take care to not over-tighten, as this will damage the filter gasket or the filter, possibly causing the Low Rider to fail.
  • 11 Open the oil reservoir, using the funnel; fill the tank with the fresh oil and close the reservoir.
  • 12 Run the motor for a few moments to coat the engine with the new oil. Check for leaks. (If you find any, check the filter and drain plug for a tight fit.)
  • 13 If there are no leaks, after the motor has run for a few minutes, turn off the motor and check the oil level. Top it off if necessary.

  • hope this helps

    check the intake gasket if it is leaking make sure the water pump is not leaking, check the heater core coupler sometimes those get brittle and crack.

    Smell gas in car

    Look for fuel leaks in the engine bay or back by the tank where you fill up the the tank. A little bit of gas will go a long way so if you had spilled a little while removing the nozel at the gas station the filler neck will disperse of it, sometimes it gathers on the inside of the fender, and causing for a smell that may not be an issue. On the other hand if you notice the smell under the hood you may have a leaking fuel line, check to see if anyone has replaced the fuel filter recently sometimes the technician does not tighten the lines securely causing a little fuel leak. other times its just a little fuel spray from not releasing the pressure before removing the filter may have sprayed the fuel on the car onto maybe the insulation. One thing to do is look under the car while it is running myabe after filling it up to check for leaks. If your notice a drip while the A/C is running dont be alarmed as this is the condensation dripping off as it is supposed to.
