Recommended Posts

We just figured out one of the injectors in my 1990 SE is toast. I need to replace injector(s). Does anyone know the cross fitment from a parts store?.. Cant tell who the injector supplier is, but it says RP (logo), and part number 72795235364... Pretty sure we are running Delco fuel system. Delco ingnition for sure...

Thanks, Chris

P.S. Getting close! :blush:)

The original 4 primary injectors are Rochester (Crap), they are 370cc/min = 36lb/hr LOW IMPEDANCE peak and hold type injectors.

The secondaries are 2 190cc/min=18lb/hr HIGH IMPEDANCE Saturated type injectors.

I replaced mine with the below injectors and never looked back.

BOSCH E5ZE LOW IMPEDANCE for the 4 primary injectors.

36lb Bosch-Brown Top


Bosch/Ford E5ZE

4/Set $202.50

Low resistance: 2.8 Ohms



and the Secondary injectors are

19lbs/hr Yellow Top*

FordBosch FOTE-D5A

Mustang 5.0

F-Series 5.0, 4.6, 5.8, 5.4L V-8

Explorer, Ranger, Aerostar 4.0

He will break a set to sell you two if you tell him it is for a Lotus, they should be around ~$41 each.
