Well done for finding a TJ system after so long, and for working on a Lotus 30.

 

I have a pdf copy of the system  and its installation called " Publication TJ/1 issue 3" .If that is the Mk1 bok I can send it to you if you PM me.

 

Getting the original pump may be challenging but its belt driven so I guess an alternative woud be avaiable. What the FIA would want for appendix K compliance I dont know.

 

Do you have rthe metering unit among teh parts on your two manifolds and where did tehy come from please ?

What engine is this for? Cosworth?

A Hilborn or similar mechanical pump would do the job. A new one as most old ones are stuffed. Depending on the pressure required. They usually pump about 40 lb. And you can regulate them down. I know people who have regulated them down to 9lb on methanol

With the right electrics [and on petrol] possibly a high volume efi pump would do the job as well

The TJ system is purely mechanical and has low pressure non-sequental injectors. In that respect it is  like the Hilborn systems but it is far more sophisticated as it was designed for production cars.

 

It has two pumps, a low pressure electric one to give basic pressure, and a engine-driven mechanical one to actually inject. The pump and control box have some clever valving to ensue the system is primed for starting and held at constant presure regardless of output. The control cam is throtle cable operated but includes a choke or start device.

 

IIRC There ar some basic mixture problems due to lack of barometric compensation and the  pump output may be geomertic and not linear to revs as I think it is centrifugal.

 

It was used by Lotus on the Ford 289 V-8's and Lotus even installed to dyno cell to run the V-8's on TJ.

 

It never make it onto a production cra and was changed to electronic control but to late  to avid being steam rollered by Bosch.

Dear Andy.
I got a Lotus unit as well.
Got many parts gathered the last decade.
Maybe we can help each-other.
Also got a good book describing the Tecalemit Jackson Petrol Injection system in detail. A little more information than the manuals you got probably. Check the images.
We shall keep contact.
