I am running carbs on my 2056 so I performed the simple mod as described by SirAndy in the Tech Articles. One thing I have noticed with my car is that my fuel pump runs continuously with the key switched on. The fuel pump is a rotary one that I bought from the Type4Store.
I didn't like that fact that my pump kept running so I took matters into my own hands. I modified a Bosch CIS fuel pump relay to work with my car. It needs a signal from the negative side of the coil to provide power to the fuel pump. So unless the engine is cranking or running it won't start up the pump. Nice to have the extra safety margin as well. The relays are easy to find in the junk yard. I only paid a couple dollars for 3 of them. Attached image(s) |
