The GMC CCKW

I know some on the board have converted to an electric fuel pump on there trucks and probable run in to this problem to much pressure to the carb, is there a in-line regulator that i can get to control the pressure and not cut the flow to a trickle. I have tried NAPA but in my area they have quit selling these.

SnowMan, is the electric pump going to be your only pump, or is it in tandem with the original mechanical, and just for priming?

It's my primary pump the mechanical one is still there but i'm not using it.

I have not had any problems with too much pressure with any of my electric conversions.

I will get the model number of the one I have used 4 times now (4 vehicles). It is not cheap ~$65

I have electric fuel pumps on all my running vehicles. CCKW, 2 Chevy Fire Trucks, and the WC-54.

It is this one (even Amazon carries it for $44).

They make a couple of different models with pressure varying depending upon the model number....I believe this one is 3 PSI. Do a google on "E8016S electric fuel pump"...Tons of information.

You can even use it to overclock your Computers CPU ..... Info can be found on this page....

Thanks Weasel nut , The pump i have now is a impeller It works well just to much pressure i think a regulator is all i need , I wonder why that guy was trying to pump water with a [ fuel pump] ,oh well it never ceases to amaze me.

BTW.

The MOST important filter is BEFORE the pump. Use one of the clear ones so you can see when/if it is getting clogged from crap in the tank/gasoline.

Notice the label on the pump in Bill's pix

I'm a full believer on filters i like to use the clear ones also, one before the pump and one at the carb. Ive never had a problem with trash stopping up the jet's . I guess I'm kind of limited to the pumps i can use my truck is still 6 volts.

Snow Man,

The same company makes a pump just like the one pictured in 6 volts. I own one (the Searchlight and Hobart Welder are still 6 volts). Number is E8011.

Also listed on Amazon for about $45 USD

Guys be careful with the clear plastic filters. Here in Canada some of the insurance companies will not pay out if you have a fire and are using a plastic filter. I do insurance appraisals on antique vehicles and one company this year has requested that I photograph the fuel filter if it is plastic. It would be better to buy a glass sediment bowl and install it if you want to see the fuel in the system. Remember Canadian insurance companies are largely owned bu US companies, so this will be coming to a state near you.

I found this at J.C. Whitney, I will post if it works or not ! I will definitely haft to be painted http://www.jcwhitney.com/autoparts/Prod ... 62/c-10101

I use both the original style mechanical fuel pump and an electric fuel pump hooked to a toggle switch. Being an old pilot, I love back up systems. Vapor lock has always been a major problem with old vehicles and in a parade, at slow speed , on a hot day vapor lock can mean a stalled vehicle. The electric fuel pump is a great standby to solve the problem.

I have the JC Whitney regulator on my 41 CCKW. Set the fuel pressure regulator to 2lbs. pressure.

Another option is to buy the positive displacement diaphragm electrick fuel pumps that have a built in regularor. JC Whitney carries these. Stay away from used one or even NOS ones on Ebay. They might be new but if the rubber diaphragm has dry rotted they won't hold up long. That happened to me with a Delco I got that was brand new, in 1970.

Got the J.C. Whitney regulator the other day ,seem to be made well but it sure is CHROME !! Same here AD have melted down some of the NOS one's myself.
