Electric fuel pump w/ a carb

[bigjbear]

I need to rig up an electric fuel pump and a temp fuel tank to move my GMC around. It is stock with around 200,000 mi on it. The biggest pain is going to be plumbing it into the Quadrajet.

My only question is what PSI and/or GPM do I need to be looking for. IIRC, 7 PSI sounds right. I'm not sure 4 PSI would be enough and I'm pretty sure ten woul be too high.

I think something like this will work.

That pump should work fine. Honestly I'd go look at Autozone or the like for a cheapo pump since it's temporary just to move around. 4psi is low but still enough to idle around, it would probably die (starve) if you gave it any heavy throttle though.

Edit: 7~8 psi is what you'd want for a stock carb'd motor.

How far and how fast?
I drove home almost 45 miles with a outboard motor gas can pumping the bulb every so often.
Put the can on the seat next to me and took off.
Pumped faster when I was passing.

And I have moved junkers in a junkyard by setting a 5 gallon can on the roof and letting it siphon down.

Wouldn't do that on the highway though, without some duct tape to hold it on.........

I like the O/B tank idea, hadn't thought of that one.

I've got to drive it on the road, so I'd rather have a real pump.

Yep, the OB will work, but it takes a lot of pumping.

Fortunately I was 18, so my right hand was well developed and used to lots of repetitive motion........

We moved a few cars around at the junkyard by filling the widsheild squirter tank with gas,and putting the hose into the carb's air bleed nozzle,that leads right to the float bowl chamber..didn't run great but it did run,long enough to get it to the main building!..had to hit the "wash" button when it started to stall out..one friend of mine claime he drove a Ford pickup home 15 miles on back roads using this method when his fuel pump croaked ..

Any electric pump that puts out 4-7 PSI should work fine,but be aware they make two kinds,one for fuel systems with a return line,and ones without one..they must be mounted as close to the gas tank as possible to work the best and live the longest too...

I'm just using a 5 gal can. I need to bypass the whole stock fuel system for now.
