Hi, thank you for contacting us. You can use any bottle with a 38-400 thread finish. The most common size used is a 4oz clear bottle. If you can wait, next week we will have this bottle available in our Amazon store.

Is this pump compatible with the bottles Caterpillar dealers use?

Hi Dan, thank you for your question. I'm not familiar with Caterpillar's bottles, my apologies, but you can use any bottle with a 38-400 thread finish. Please check with them if they bottles have this type of thread. If there is anything else we can help you with, please do not hesitate to let us know. Thank you.

Buenas tardes, en la compra incluye el tarro y la manguera?

Gracias por su pregunta. viene solo la bomba, sin tarro ni manguera. Si tiene alguna otra pregunta, no dude en hacérnosla saber. Gracias.

Does this work with Amsoil test kit bottles?

Hi, thank you for contacting us. This pump can work with any bottle as long as the bottle has a 38-400 thread size. If you would be interested in buying some bottles we have them available in our Amazon Store, we have packs with 6, 17 and 35 bottles. If you have any other question, please do not hesitate to contact us. Thank you.
