I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions
Q: Does this kit require any special tools to install? A: Installation typically requires removing the valve cover and carefully prying out the old membrane; a small pick tool may be helpful but no special equipment is mandatory.
Q: Will a failed membrane cause a check engine light? A: Yes, a torn PCV membrane often triggers lean mixture or system too lean codes (P0171, P0174) and can also cause noticeable oil consumption or smoke from the exhaust.
