'89 Esprit Turbo Split Fuel Injector

Recommended Posts

I own a 1989 Esprit Turbo (non-chargecooled). After a long search for an intermittent fuel leak it was discovered that one of the Lotus-fitted fuel injectors was split. The injector has "0078-5235364" written on it. The split extends 70% around the top of the plastic-bodied injector and is nearly horizontal. Strange.

Has anyone else had the issue of a split fuel injector? I imagine more than a few cars have burnt if this problem exists elsewhere. No one I have spoken to seems to be able to provide a reason for a split injector like mine.

Also does anyone reccomend a suitable replacement injector . . . ideally a set of 4 of them?

Many thanks.

Andrew, I've never heard of the injector splitting, but my suspicion is that the car sat for a long period of time or the engine was run hot a few times and the heat was transferred to the plastic body of the injector. I'd suggest a set of injectors from WC! Very good and easy to install. They are also cheaper than the Lotus parts.

I replaced mine with BOSCH 36lb/hr (370cc/min) LOW IMPEDANCE injectors.

I bought mine for ~$46 each from

Bosch/Ford E5ZE

4/Set $249.50


These E5ZE Bosch injectors are brand new and flow-matched to within 0.5%


These are the correct size and type for the primary injectors on all GMP4 DELCO injected Lotus Esprit 89 & 89 SE-95 S4s.
