If you are running a stock fuel pump,no reason for a reg. Not enough pressure from the stock pump. Check out the carter electric. There is a company in CA. that says you can run this with out a reg. puts out pressure perfect for a weber. Will find the site on SUN
 
I've always been happy with the little Facet rectangular pumps (tho I use the low pressure version without a regulator). Unless you've made other modifications to substantially increase power, I think the 4-6 psi Facet would be a good choice.

I agree -used to race a highly modified VW golf 1800 with twin webers,used a facet pump and regulator and never gave me any probs -very reliable
 
The ~FACET~ low pressure electric fuel pump has been very reliable in my race car (and for years before that when it was a street car).

But it *is* noisy! Even wearing a helmet, I can hear it.

If you use the Facet, you may want to mount it on rubber mount to dampen some of the noise.

Then again, I've owned a TR3 and, with the top down, the wind noise will make you deaf anyway.... /bcforum/images/%%GRAEMLIN_URL%%/jester.gif

You can buy this pump from Aircraft Spruce (link above) , but also from your local discount auto parts store (like "Autozone", "Advance Auto Parts", etc). It may not be branded as "Facet", but you will know it by it's rectangular shape. These places sell online too. You can also find it at Summit Racing or even JC Whitney (both online too).

I doubt you will need more that 2 to 3 lbs of pressure for those Webers, so make sure you get a low pressure pump.
There are many types of regulators available. Summit Racing sells a Holly regulator for under $30 that is excellent. The dial-type Purolator regulator is considered poor and, in fact, the factory recalled many of them.
 
I don't understand "mp" in the thread topic as it pertains to electric fuel pumps. Am I missing something here? /bcforum/images/%%GRAEMLIN_URL%%/confused.gif
 
My guess... he was keying in a subject line, got ahead of his browser & all we got were the last two letters (of pump).

...and somewhere in cyberspace there is floating around an "electric fuel pu".

Thanks George,
The coffee is still brewing, so I was not getting that thread title at all. Thanks for making it clearer. /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
 
Ron, you might check the recommended volume for your Webers. Then make sure your choice of pump will actually push enough fuel. No matter what the pressure is, if the volume is not sufficient the engine will starve out.
You can check your current pump by filling the float bowls and disconnecting the fuel line before the carbs. Then hold the line in a container and run the engine until it runs out of fuel. By timing the run and measuring the fuel you can figure the volume, GPH, of the pump.
The volume will need to be sufficient for maximum power and RPM plus an amount for a cushion.
 
Thanks for the responses re my TR3 fuel lpump question (I don't know where the MP for the subject came from either_)
Fortunately you folks were curious enough to take a look at it and give me some good ideas.

/bcforum/images/%%GRAEMLIN_URL%%/iagree.gif But it doesn't take much to quiet it. The one on my Stag is soft-mounted to a plate I made, which is then soft-mounted to the factory plate; and I can just barely hear it with the engine off. I'd say it's quieter than the stock SU pump.
