Electric fuel pump for twin carbies

im thinking about running an electric fuel pump and regulator on my twin carbie setup but have few questions as i am not very experienced in the field of fuel pumps

1. is it worth it on twin stromberg setup
2. cheap vs expensive is there much difference
3. where would you mount it
4. what sort of PSI would i run

Below is the pump and regulator im thinking about buying but im still not sure maybe someone may have few suggestions for me of what to buy and what to avoid

PROCOMP HIGH PERFORMANCE
ELECTRIC FUEL PUMP + REG

PROCOMP "BLACK"

Compatible with alcohol or methanol fuels

This regulator is adjustable from 4 to 9 psi
It has one 3/8" NPT inlet and two 3/8" NPT outlet ports
Comes complete with mounting bracket.

Cheers
Mark

Hi Mate,

I bought the same setup. Cant give you advice but I am not doing electric any more. If you need a fuel pump and reg they are brand new never touched.

Stick with a standard mechanical fuel pump. It's quieter, easily repaired, flows adequate fuel and far more reliable than anything Procomp will ever make. 140 US gallons of fuel per hour is about 10 litres per minute. Do you really need that much fuel?

So maybe its better to buy high volume mechanical fuel pump

Also if it helps the car will be used for mostly track work and im looking at putting fuel cell in the boot

Maybe you should find out specifically what the better HQ racers use. I'm sure they will know of a top setup that is reliable..

a good hq racer will use about a litre of pulp every minute.

mechanical pumps are more than up to this. some people run electrics but to me its another thing to go wrong. any fuel pump dnf's are usually the result of wiring, connections etc...

watch the chinese mechanical pumps, some put out too much pressure (have seen 9psi!!) and the needle and seat cant seat properly.

Are you running a red/blue/black six? If so, the small block chev mechanical fuel pump is a straight bolt on replacement. I would still use a regulator though and would try not to go any higher than 7psi if you are using either strombergs or su's.

Look for us on Facebook "Detroit Industries"

Hi all

The standard mechanical pump will cope, as your carby needs are not that high.

I run a holley red (no need for reg it is low volume low pressure ) on my HJ 253 only because the mechanical fuel pump is a bit sus and also after the car has been sitting 2 days the fuel line is drained.

I use the electric pump now to prime up the system for about 20 seconds, then pump the pedal and she starts first pop, i then turn of the electric pump.

I will "one day" change the manual pump and run a kit through the carby

The main problem is the noise of holleys, you will always get that rattle rattle click click noise at idle

I believe carters are much quieter

If you can work out your fuel issues, use the electric pump and plumb a return line with a 1 lb restrictor and return fuel to the tank, this was the fuel keeps circulating, stays cooler and wont strain you pump when the engine is not sucking fuel

regards
george

Thank you everyone i think i might leave the manual pump in there for now until i put the racing 186 in next year then i will revisit it and see if it will be needed

Sadly im still not sure where or what class to race it in as i got letter back from cam's today stating that i cant use it in the Nc historic touring car class because its not a manaro which has knocked down my spirits so i guess i will look at other forms of racing and see what the rules and specs are maybe hill climb car or something

How much fuel does a needle and seat/s on a pair of old Strombergs flow?

Make sure you use Fuel Hose Clips and not those in this photo ... http://gallery.oldho...

The indentations left in the Hose (rightmost) can cause the Hose to fail under pressure.

Fuel Hose Clips are smooth and are designed to grip the Hose equally all the way around.

You see the proper Clips here ... http://holdenpaedia....
