Difference between Wix used oil analysis kits 24078 and 24077?

[apollo18]

Hello,

I was looking at the WIX used oil analysis kits on rockauto and have troubles telling the difference between these two.

Wix 24077 just shows the sampling bottle and its selling for $17.50
Wix 24078 seems like it shows the sampling bottle and some tubing and its selling for $13.46

The 24078 from photo looks like the more robust kit however it is selling for cheaper

I tried to do some google searching and I cannot seem to be able to tell the diff

Anyone have an answer?

Thanks

According to an AI search, the only difference is that 24078 includes tubing. Perhaps the pricing is lower because it's a higher volume product. I can't imaging the tubing costs more than a few pennies.
