Have you bought o-rings, cups? I guess my fuel injectors are leaking, want to change all rubber.

I want to take off my fuel injectors (Ford Ranger 1998 4.0 OHV) and change O-rings, cups and etc. I looked on Amazon Uremco, but here so much versions. Can you advice exactly part number of repair kit.

I ordered same, but doesn’t work( Maybe very old o2 sensor.

Hello everybody. I used cleaner for fuel injectors, changed downstream o2 and up left. Right sensor I can’t unscrew, rips off the nut( (Tried heat it, but still can’t unscrew). Also very little space for screw wrench. Will take off exhaust in spring or summer and unscrew with more space on...

I appreciate

Can I use this?

Ok, thank you. Will try to change.

Air filter is usual. MAF is clean

What is brand of sensors should I buy? Bosch (2pcs upstream and 1 pcs downstream)? If yes, what is part number. Thanks.

Spark plugs is Autolite. Will take off fuel injectors in next week.

I try to drive like a grandma) Is it bad if pressure down when engine turn off?

Hi guys. Today checked my fuel pressure. When engine works is 65 psi. When I turn off, pressure is go down until 20psi during 3 minutes. Engine works good, smooth, but I have 12 mpg. Is it bad pressure? Could be problems with mpg? How can I fix it. Thanks.

Maybe gauge from Harbor Freight is crap)

Hi guys. Finally checked fuel pressure. On idle around 50-65 (was different pressure each time). But when I turn off, pressure down until 20 (during 15 minutes). Is it bad?

Mine engine works smooth. Ok, thank you
