carb to injection

Post by robinm » 11 Oct 2014 10:14 pm

Hi all, I have a very nice 360GL and am about to buy a GLT as a parts/donor car.
I would like to convert the GL to injection and would like advice on this, is it feasible, what is involved. Any advice welcome.
The main reason I wish to convert is to say goodbye to the diabolical solex 34-34 carb.What a pig of a carb to set up!!

It is quite easy, even better when you have a donor car at hand. The wiring isn't that hard, if I remember 3 or 4 wires that you have to connect. Hardest part is changing the fuel tank, you will need the injection fuel tank! The rest of the parts you just unbolt from the donor and bolt in your enginebay.

If you know how to use some spanners and know how to read a wiring diagram then I think a long weekend is all that is needed.

I think you might need to block off some of the water ports in the head that heat the manifold.

I have a good 360 carb if you want it.

Sorry I have been away. Re changing fuel tank, is that a must do or can I rig up a return line to the existing tank, which I am sure is possible?

Hello,

You want to change the tank and all the petrol lines. the ones that are in the carb car could work though i have ran them for a while. But when you have a parts injection car next to it i would deff swap tank, pump, lines.

Regarding your electronics, swap over the complete engine compartment loom (yes also the one for the lights etc), DONT swap in just the injection loom. it looks all the same but like i stated in my project the fuelcutuff for the carb can give some trouble compaired to the injectionloom. Its fairly easy because all the wiring does slide into the fusebox

Thanks for the advise, looks like a slightly bigger job than I originally anticipated, but then again I do like a challenge!!

Injection pumps need some input pressure, they cannot suck well given the cycling volume needed and either suffer cavitations or collapsing input pipes, not quite sure exactly what the problem is but people have tried it and suffered intermittent fuel pressure.

You could use the carb tank if you use an in-tank lift pump or a full injection in-tank pump like the 940. The 360 injection uses a bottom outlet and return connection to feed the pump.

I don't think it will be that hard but obviously you need all the details. I had also intended to do the same but going a bit further now with a carb to B230FT.

I have only used the B200E engine wiring loom, and there where only a couple of wires to connect to the original wiring harness. Could take a look if it's needed.

I took some pictures, these are the wires that I modified to get the injection going. It is some years ago so I don't remember exactly which wire went where.

The first picture shows two yellow-blue wires that go to the starter motor. I guess in the original wiring harness they both have their own connector.
Image

The second picture shows a thick black wire and a small dark brown wire. If I'm right the thick black one is going to the fuel pump (there should be a fuse somewhere in there). The brown one is ground or switched 12v+ (Not sure about that one, you should look that up in the Haynes manual).
Image

And the third picture shows two 12v+ cables going to the battery.
Image

The rest of the connectors on the wiring loom is plug and pray.
If you have more questions, just ask!

I thought one had to go to the ignition module.

My topic might help, or confuse

That could be the brown wire, switched 12v+. Spliced in with one of the wires on the A-plug on the renix.
