Injector lines IO 360 A1A

[Shadrach]

Greetings all. 

I was buttoning up my cowl last weekend and noticed that my #2 injector line is of a smaller diameter than the other 4. The engine runs fine and has well balanced F/A ratios. But it makes no sense to me. I called the engine builder to get his thoughts. Has anyone ever sen this?

All of mine are the same size.  I see in the parts manual where a couple of the IO 360B1x's use a different line than the A1A's. Perhaps someone installed the wrong one at some point

they sould be the same diameter as per the engine parts catalog. Do you have the parts catalog ?

 P/N would be LW-12098-0-140 and LW-12098-0-210 (two of each for different lengths).

Since the spider and the injector themselves have the same connector size is kind of hard to have a different tube size than the others.

I talked to my engine guy and he said that depending on when MFG took place it's possible 2 lines that have different OD but the same ID.  Jose, the nuts are the same at the spider, as long as the line is flared to the correct size, it will work.  I'm going to investigate further... With my luck, the current line will be the wrong one, but replacing it with the right one will screw up my F/A spread.

I might have some from an -A3B6d for you.   Send me a photo and I can exhange them from our core motor. There is also an AD on the lines.  Every 100 hours now, plus anytime one is disconnected, they have to be inspected.
