Hi I'm trying to go su carbs to my 3.5 v8 but I don't know where all the hoses and pipe should go. Does anyone have a diagram or could put up some picture that would help me. Many thanks

Anyone got any pictures of a twin carb set up. It's replacing injections inlet so I need to know how the fuel lines are run.

For some reason it's only showing left side of photo. Try opening image in new tab. You'll need to change to low pressure fuel pump

Paddocks probably.
It's going to be a bit of a downgrade performance wise from efi to su

Efi hasn't worked since I've owned it. Only ran on Lpg. The ecu isn't sending an earth signal to the injectors so I'm just getting rid and going to carb as there easier. I can't get a ecu with the same number as mine.

I admire your reverse engineering, facet type pump will be fine, [ebay] fuel lines just route them safely - good luck

Any small facet pump will run ok and you don't need to have it in the tank - they will suck fairly well. I went back to carbs on the 3.9 some time ago. Put a inline fuel filter before the pump and again before the carb just to be safe. The fuel pipe runs up and across the top of the bulkhead and round to the nearside carb. There is a link pipe between the two carbs that feeds the offside one
