SD1 Rover 'Flapper' Efi System

[enigmas]

About 6-7 years ago whilst collecting some parts from a local auto wreckers, I noticed a couple of SD1 Rovers nestling among the piles of slowly decaying car bodies. Between the 2 SD1s and a couple of Jaguars I managed to remove a complete fuel injection system and another set of injectors from the Jags. There's also some very comprehensive files on the net outlining both the operation and trouble shooting of these early systems. As my car will remain primarily LPG fueled I thought this might be an interesting addition if I'm ever in a situation where LPG isn't available. Another upside is that these particular EFI manifolds distribute gaseous fuels very efficiently as the runner lengths are all equal lengths.

Here are some pictures of the components before and after cleaning. I've also modified and repaired the wiring harness for easier fitting/servicing and removal.

I have a Range Rover Fuel injection system laying in my garage for over 10 years. I thought about fitting it to my MGB V8 but the SU currently fitted never give problems and are easy to adjust. Will not fit it to my P5B as it runs on LPG and therefore doesn't give any advantages. These systems can be bought rather cheap in Holland.
About 1,5 year ago, i bought a spare V8 RR engien with a complete injection system for Euro 250,-. As i already had a FI system, i sold it for Euro 90,-

Vince,

I've recently removed the 'flap' meter from my Rangie after abandoning petrol. The injector hoses started leaking about 12 months ago and new hoses didn't solve the problem. Every now and then I'd get a petrol fountain under the bonnet, which wasn't very comforting. I had to pull the fuel pump fuse to stop it. The injection specialist who cleaned and tested the injectors 18 months ago said that the original Lucas hoses had an odd non-standard internal diameter and it was no longer available. He supplied the closest equivalent, but it was very slightly bigger. So I'm now running gas only, which is a bit inconvenient as the LPG tank is small and the gauge woefully inaccurate.

Anyway, you're welcome to the 'flap' meter plus a spare, if it's of any use. I also have a set of spare injectors. I don't need the throttle potentiometer either, and the computer will be coming out eventually too.

Hi Warwick, that's bad news, but I don't understand your specialist's reasoning. The hoses are readily available from this company in the UK (link below), cut to size and with clips, or you can do what I did and go to ENZED and purchase 1.5 metres ($28) of the appropriate hydraulic hose and cut it to length. I also bought a dozen stainless crush rings rather than use screw clips.

As for the injectors, they're easily cleaned and checked if you have a compressor, some suitable hose and a 3 volt power supply (Jaycar). There's also guy on the net (retired electronics engineer...Ramon) who has a dual plenum SD1 and has written and compiled a virtually diagnostic manual in PDF format, which is freely available on the net if you search.

As for the components Warwick, sure, if you're done with them I'd be happy to take them. (PM me)

PS.
If you're absolutely over the efi system Warwick and just want a simple backup to LPG, why not fit a straight forward twin carb manifold system. I'll come up and give you a hand fitting it. They're about as low tech as you can get and you don't have to worry about complex electrical systems. (I'm very good with tuning and sorting CD Zenith Strombergs...(even the water choke systems) SUs are fine, but my preference is for the former with a simple manual choke. If you still remain dual fuel, the choke for petrol is virtually irrelevant.

Hi Vince,
Mine's the first of the EFI Range Rovers and the injectors are Lucas.
I did intend to change it to the early Stromberg set-up for the occasional petrol use. Much simpler than all the EFI clutter under the bonnet when you only need petrol now and then. I have a manifold and Zenith Strombergs in the shed. (I used to have a '76 2-door Rangie)
Sounds like the SD1 set-up is different.
