My question is regarding the Yanmar filler cap. For some reason my Yanmar 2GM20F has a large 1 ¼” hose connected to a filler “neck” piece on the top of the engine where the filler cap would normally be. When removing the 1 ¼“ hose from the engine filler “neck” to refill the radiator fluid the “neck” broke off and now I’m unable to connect the 1 ¼” hose to the engine.
I was looking to replace this “filler neck” and after looking online this part does not exist. I’m only able to purchase a normal filler base & cap as expected that would then run a normal overflow pipe to the external subtank. I wouldn’t expect any radiator fluid “overflow” would ever make it to the subtank since the hose is 1 ¼”!!
This is a 1 ¼” x 4' hose that connects to the filler “neck” on the engine and the hose extends outside of the engine compartment into the battery compartment located under the seat in the cockpit. The opposite end of the 1 ¼” hose then connects to an external filler cap that has a short overflow pipe connected to the external subtank located in the underseat compatment.
Is the above a valid overflow setup or should I purchase a normal filler base & cap and run a normal ove rflow pipe over to the subtank located in the underseat compartment? I noticed the overflow pipe should be a the same level and should not be longer than 1 meter which may be why this setup this way.
I hope this make sense and this can be resolved relatively easily. I will attach some pictures to help explain this issue. - Thanks in advance for your help!!
