Re: 1984 Chevy S10 motor swap
Pretty moldy thread, but a legit question...
E pumps push fuel, unless it is a British SU diaphragm style E pump.
Since your truck was a carb model, the best place to install the pump is on the frame rail right behind the driver seat area.
You can run a hot lead from any key + hot lead, most will recommend adding an impact (inertia) shut off switch too - available on Ebay, Summit, Jegs etc. This will kill the pump in the event of a motor wreck.
It is also a good idea to add a fuel filter before
BTW, there are several E pumps available. You will need a LOW pressure model for a carburetor application. (about 5 LBS line pressure). They run from $35 to $100, depending on style and manufacture. You don't need a racing pump, they are generally very loud and are overkill for your application.
You can also add a fuel pressure regulator, but that is optional since the low pressure pumps are designed for this application.
Plug the vacuum line, it will be fine.
Hope this helps...
Confucius say: Truck with new engine need good pump...
