I just read the artical in the latest issue of TW concerning the electric fuel pump, I have a 51 Champion that is very hard to start after setting for a couple of weeks and this sounds like a good cure. I like the idea of the oil pressure safty switch the best but am trying to prevent using the starter so long to get fuel pumped up. Therefore the Ford enertia swith sounds like it would be the best. Have any of you used both methods and if so which one did you like best?

I have been installing solonid type at the fuel tank, hooking it up with a lighted toggle switch off the acc side of the ign. Turn the pump on, wait 5-10 seconds, start engine and turn the pump off. Also a good back up in case of vapor lock. Jim

I done the same as Jim, on my '53 Champion. A great improvement!

Did you guys use the regualtor? My Champion is still 6 volt and according to TW the 6 volt electric puts out 5 psi and I think that is about right for the machanical pump.

Here is a very good Compact 12Volt Electric Fuel Pump (6 Volt Also available) from a trusted SDC and Forum Member, not me just a friend. :)


NOT a selfless promotion! ;)

Just received this month's TW and it has a very thorough discussion of electric fuel pumps.

You could use the oil pressure switch for safety and add a momentary contact button for priming.

I have electric pumps on all my Studebaker's. Sure makes it a lot easier to start them after not running for some time.

I put a electric pump on my 51. Before I put it on I was getting 7# pressure and after I was getting a little less than 5# pressure. So I took it off. When it sets for a while I just spray a little Carburetor cleaner in and start it.

A Champion should run just fine on 5 P.S.I. didn't it?

But mine is a V8 it started out a 6 but in 1985 it become a V8

5 psi sounds a bit high.
I installed a 7psi Carter pump on the still 6 volt system. Works just fine. I just reversed the wires to turn the pump the other direction..!

I had to install a regulator (was planned anyway..) and I adjusted it to 3psi. It seems to love that pressure. No flooding and no starving at full throttle...which is where it's at most of the time...!

Right now it's just on a full manual switch. I turn the pump on to prime, off for starting, and back on for driving. No mechanical pump.

That's not a big problem. I have a Holley FI pump on the Lark with a simple 3 port Holley regulator(modified to a four port for the supercharger reference line), and I just turn mine to the specifications on the carburetor. The R2 carb called for 7 psi, so I set the fuel pressure for 7 psi.

However, both the Lark and the '55 are fully electric and the pumps are always on when the car is on, there's no mechanical pump at all, just a block off plate where it used to reside. They both do have manual switches to shut them off if necessary.
