Electric Fuel Pump Regulator By rp (Read 2,763 times)

[rp]

Now that I know I need the electric fuel and know what I'm looking for, a 2-4psi pump is fairly easy to find. NAPA, Pep Boys, ete.
What I can not seem to find is the regulator that should go with it. When I mention I need a dial regulator, know one seems to have it (Unless I haven't looked hard enouth)
Thanks in advance.

What a clown, I'm answering my own post. I just found a site
Summit Racing (.com) Has 2 dial regulators.

Mr Gasket 1-6 psi 27.00 + 9.95 ship

Spector Performance 1-5.5 psi 32.95 free ship

Any suggestions welcome.

First of all welcome to the forum! I just put up the video section and here's a great video on the pump install:

A lot of people who run the fuel pump that he mentioned at 2.5 to 4.0 PSI never need or install a regulator as this amount of pressure will not over run the carb needle. But if I did use one this would be the kind:

Let me suggest another option if you're having fuel delivery issues and it's this;

Easy to install half the time and a lot cheaper, and if it ever goes out one can buy a rebuild kit, good fuel delivery with a lot less hassell.

Again glad you're here!

Have to agree with JR. I have been running an electric fuel pump for a couple of years with no regulator. No problems. I have read that the combination of a low pressure fuel pump and using a regulator to try to maintain a low pressure sometimes results in no pressure until you turn up the regulator into a range that the fuel pump alone would not surpass which makes the regulator redundant.

To follow up. The regulator is sitting on the shelf. I'm assumig the fuel pump is not strong enough the activate the regulator. But it runs the scooter. Was crusing 55-60 for 5-6miles and no slow downs. One more issue checked off the list.

Cruiser, I hope you didn't get hit to hard by the storm.

Thanks, rp. No damage here. Did lose power for about a day. At least it gave me an excuse to get my old generator up and running.

I think your analysis of the regulator is right on. If the carb is in good shape it should handle the output of the low pressure electric fuel pump with no problems.

I'm running an electric fuel pump that is 4-7lbs with no problem. In fact, the speed of my scooter has increased from pushing it to get 60-65 to being able to cruise easily at 65 and getting to 70 easily. Both with no bogging due to loss of fuel like I was experiencing before.
