I AM THE LARGEST SELLER OF THESE Fluoroelastomer FORD IDI DIESEL O-RINGS ON EBAY!

BEWARE OF THOSE TRYING TO UNDERCUT ME BY A $DOLLAR TRYING TO PASS OFF THEIR INFERIOR BUNA-NITRILE AS GENUINE Fluoroelastomer O-RINGS!

83-94 Ford 6.9 7.3 IDI Diesel Fuel Injector Return Cap O-Rings E6TZ-9229-AA

Fluoroelastomer replacement for the inferior Buna-Nitrile OEM factory o-rings.

Complete Set of 16 + 2 extra.

Highly fuel & chemical resistant 75a Durometer Fluoroelastomer instead of vulnerable Buna-Nitrile like the inferior OEM o-rings

NOTE: These o-rings ship in a plain envelope with an extra cost 1st class stamp. The "tracking" number is simply your order number. This is supplied just to let you know that they have shipped and just to help me keep track of what has shipped and what has not shipped, as I do sell a lot of these. Please understand that your order number is not something you can actually track, OK? Thank you.

NOTE #2, ONE MORE TIME!: The "tracking" number given is NOT trackable. I ship these FREE and I am glad to do that, but if you want tracking I am glad to do that also. However, please understand I cannot afford to do that for free, but I will be glad to provide tracking cost at my cost ($4) if you want that. Most people prefer and appreciate the 40% discount, but I will be glad to add tracking with a $4 payment, my cost. AGAIN, PLEASE let me know if you want tracking and I will be more than happy to add that at my cost! Thank you.

NOTE #3: Ebay's estimated delivery time is NOT correct. The delivery will be 8-11 BUSINESS days after shipment. I never go over 24 hours before I ship, so 8-11 business days is to be expected from your payment date as I have no control at all over the United States Postal Service. Thank you.

Note #4: These can also be used for threaded muzzle o-rings.
