Rubber Fuel Primer Squeeze Bulb, 5/16" Barbs

Rubber Fuel Primer Squeeze Bulb, 5/16" Barbs

The 6667170 Rubber Fuel Primer Squeeze Bulb is a simple, no-nonsense fuel priming helper for getting fuel moving quickly through compatible systems—especially handy when you’d rather not “crank and hope.” Built with an aluminum body and NBR rubber, it’s designed for reliable pumping and includes a one-way valve to help prime fuel lines efficiently. Comes as a 4-pack, because apparently fuel systems enjoy backups.
