Do this fit my 2014 Impala LS  2.5 motor ?Ruth M.Dec 16, 2022
Best Answer:Hi Ruth, I'm glad to assist you. No. It is incompatible. It is for a carburated gasoline engine. It will not work with fuel-injected gas engines. We do not carry a direct-fit one for your car.

will this fit 1985 380SE mercedes benz?Maurice K.Jul 06, 2021
Best Answer:Hi Maurice, I'm glad to assist you. No, it won't. This is commonly used on performance-tuned carburated engines. Unfortunately, we don't carry direct-fit fuel pressure regulators for the 1985 380SE. We suggest checking the local parts stores around your area or the Mercedes Benz dealership directly on what they have available to offer you. I hope this helps and happy shopping.
