Help wanted :sad:

Does the maker of your conversion kit not have documentation? All of the Weber conversions I have ever seen are to get rid of the Strombreg or SU carb setups. I've not heard of folks going from EFI. I am sure someone has but I don't recall any members here doing so.

if converting to carb from efi, why worry about the old efi harness? if you want a clean look remove it, if you don't mind unused extra wiring jut move the harness out of the way.

Are you saying you need a signal from the coil to get the EFI to pump fuel? I'm not what the exact schematics are but I know you need a relay from the ignition to turn the pump on (and bypass the EFI which can be completely removed from the truck).

Here's a link from a guy who did it in a Defender. Would you mind posting some more details/pics about this process? I have considered it before and am curious as to what your experience is.

Thanks

I"m pretty sure the coil signal is the only thing that connects the EFI and ignition.

Hello, thank you for help. Now the car passed eu-control, co measured to 1.1 .%, lover than the limit 3.5 % co.? only l need a new front windscreen to pass the control.
I do as follow. No change with the ignition wirings. Threw avay all of the efi loom.Take a new relay + from battery via a fuse to the relay. From relay to the fuel-pump. To manage the relay l take + wiring and minus wiring from the cigarett-lighter in the center consol (on then ignition are at position 2) to the relay. The new fuelpump l mountered beside the engine take fuel via the efi fuelpump in the fueltank.l plumbed off the return to the tank. I cut off the cabel 50 cm from the efi fuelpump,not the wiring from the fuellevel-meter. Need a 4-wd thermostat housing, the neck must bee pointed to the right side to fit in place behind the distributor.

I dumped a defective EFI and fitted an Edelbrock. Used the original in-tank fuel pump. I ran the fuel supply to a 't' joint, fitted a 6mm restriction on the return side, about 10cm long then up to 8mm again. Then through a fuel pressure control to the carb. Runs cleaner than an EFI, according to the EU tester...

Interesting approach going back to a carb. Your CO might be lower but your NOx might not be. But if you pass good for you. Somewhere Scandinavia I figure from the pictures. Sweden maybe? In Norway they frown on you filling up your washer fluid because it could be bad for the environment...

I was wondering, is there still a catalytic converter in there? Carbs don't provide sufficient mixture control for a Cat and if you are running too rich it will glow cherry red and can set things on fire.

Live in Norway. No cats, come later, maybe from 1990 in Norway. So everything ok about that....

Nice. I lived in Norway for 8 years (Asker), I hear it was a great summer this year.

So if you find yourself wanting for more (and with too much money spare) I recommend you take a look at these modern throttle body injector systems such as Holley Sniper EFI. They are reasonably affordable easy to install a bit more user friendly than carbs and a lot of fun to play with.

Obviously you just fitted your carb, but maybe in a years time you are ready for a new challenge.

Enjoy.
