I have a 1.7engine and will be running twin Weber 40idf's.
My car was originally a 2.0i but came minus engine and ancillaries. The only thing I have is the original 3 port pump. I haven't tested it yet but I won't be running a return so can't use the pumpin this instance. What kind of pressure should I be running the carbs at? Research and past experience (albeit not with 40's) would suggest something in the range of 2.5 to 3.5 psi. Anyone with this set up have any input/advice on pump and flow pressure? |

I used the factory wires but the previous owner cut off the plug so I picked up one of those 2 wire Weatherpack connectors for a GM car at the parts store. Makes for a nice water proof connection. Mounted the pump in the factory location I think using the same bolt hole but without an isolator.....nice and quiet. Not much of a photo.
