Hi all, I am planning to use an electric fuel pump mounted near the tank and the mechanical engine mounted pump. My plan is to use the electric pump only during cold starting after the car has been parked for a few days or the mechanical pump fails to deliver fuel. Will this work with both pumps connected to the same single fuel line? Will fuel flow through both pumps with only the mechanical pump operating without problems? The electric pump is a Carter unit with 2-4 lbs. fuel pressure and an in-line filter. I was not planning to use an external fuel pressure regulator. Has anyone done this? What precautions should be taken? Thanks in advance for sharing any experiences with this setup.

That will work fine. The electric pump will push the fuel thru the mechanical pump. When we install them, we use a spring loaded toggle switch so the owner can't forget to turn it off, if used for priming, and feed it thru the ignition switch for safety, in any case. We recommend filling the carb until the pump stops clicking. Install an inline filter between the tank and the pump inlet to catch any crud in the system.

hi CAR CRAZY I had the same problem for years, the way I repaired this starting problem when sitting for a long time., is to install a new flex line and 2 copper washers I bought for the PARTS CELLAR in MASS. This repaired the problem, you could go this route if you want to save money, the reason for the copper washers is that air leaks in the line after a period of time and lets the gas go back to the tank, BELIEVE IT OR NOT!!! my 37 can sit for 2-3 months, and will start with out pouring fuel in the carb and risking a FIRE,,,!!! but a lot of people think the electric fuel pump is the answer, good sealed fuel lines is the answer,with a good fuel filter in line,and a good fuel pump kit I ask my self what did people do before the electric fuel pump, my 3 cents worth 37RAGTOPMAN remember the leak is not on the pressure side it is in the intake side of fuel pump, side.that's why no fuel leakage out of the line,

Where do you put the 2 brass washers in the flex hose? Bill Large

The fellow I bought my 1950 F1 from set mine up with an electric fuel pump and filter by the tank and a toggle switch to prime the system. Works great. Didn't care much for the toggle switch mounted in the middle of the dash so I put a vintage looking indicator light in the hole and moved the toggle facing down on the bottom edge of the dash. Now I have this bright red light on the dash reminding me the electric pump is on. Jim... 1950 F1 Stake

one copper washer go in the fuel pump then install the flex hose INTO THE FUEL PUMP then one goes in the flex ling and install the fuel line that goes to flex line, [ forgot to mention that these washers are tapered so make a great seat to stop leakage ] YOUR DONE,,!!! This will repair the problem, hey this is worth a try before spending what $50-$100 for a electric pump, remember electric pumps are good but can cause other problems [ copper washers are about $4.00 flex line line $22.00 ap ] remember you need a good mechanial pump to start with. the PARTS CELLAR has very nice pump kits or will rebuild your pump, for various makers of autos, hope this helps,37RAGTOPMAN This message was edited by 37RAGTOPMAN on 4-5-10 @ 6:46 AM

Isn't there also a guy that makes a new fuel line with an anti drain back valve in it? Resistant to modern fuels as well I think. Seems like it was in the $30 range.

I have heard and seen the ad, but you still need to seal the line CONNECTIONS, I would like a few people that bought one give us FEEDBACK on the fuel line,and tell us how good it is, this would be a benefit to many V8 FORD PEOPLE I guess that is another way to repair the fuel leak back problem, I wonder if it will restrict the fuel flow at high speeds, but assume it will not, this is nothing new, all fuel injection cars have such a valve to hold the fuel pressure for easier starting,just that it is much bigger, I remember every spring, the WORK,I had to go though to get the 37 to run dumping gas down the carb,about 4 or 5 time to get the PRIME back and fuel up to the pump and carb, IT WAS NOT FUN,[ AND " DANGEROUS " one wrong move and you will be TROUBLE BIG TIME, ] and I assume not good for the engine either,raw gas maybe getting in the oil etc,PLUS saving the STARTER MOTOR and BATTERY. I can say that it might crank a few times but will start and run with NO MORE problems. But it is best to run you V8 a few times during the winter storage,had mine sit for maybe 2 months and still starts, during the winter [ end of DEC or beginnig of JAN ]in a warm break in the weather will start and run till it gets warm, my 3 cents worth 37RAGTOPMAN the 2 tapered copper washers are worth their wait in GOLD to me,

I use an electric primer pump for convenience. My car sits for long periods of time, and it greatly shortens the amount of cranking. For the record, my fuel system is new from tank to carb. After weeks of sitting, and a heat soak from long drives that evaporates most of the fuel in the carb, which isn't much, considering that the float takes up most of the room in the bowl, the booster does the job. We like the Airtex pump from C&G because it comes with a check valve to prevent drain back. My booster did get me back home when my mechanical pump failed, and when my original fuel line clogged to the point the stock pump couldn't pull enough gas. It sure made the $60 I spent worth it. If you don't want one, don't put it in.
