My mate who helps me with my buggy thinks that we can't set up the carb due to low fuel intake at the carb, so he thinks that a electric pump may fix the problem with constant fuel pressure, he had it once on a vw bus and fitting an electric pump fixed the problem, (this is a new carb), set it as instructions with little adjustments when you come to a halt it just wont tick over and when it doe's start wont tick over correctly thinking lack of fuel.

...... with a regulator in line.... sounds like the exact problem I had 2 years ago. Usual mechanical pump was giving too much pressure to the carbs. used a decent regulator and that issue was soon sorted.

What Snoopy says - I ran twin carbs for several years with a mechanical pump, only changed to electric as I wanted to declutter the engine (and tinkering is 1/2 the fun)

If you want to reduce pressure then a regulator is needed as Andy says but you suggested you were getting fuel starvation rather than flooding

Hi, fitting an electric pump will only help if your standard pump is knackered.
A standard pump will handle small twins, so no probs to a std carb if its working well.

I've run a 2008cc engine with dual 40 Webers on a standard pump with no issues at all.

When I changed to an alternator I swapped the mechanical pump (they are different to clear the pedestal) and the actuator rod.
Ran fine until you hit a hill then laboured all the way up it, then fine.
Idling was iffy sometimes it would, sometimes not.

Turned out the actuator rod was slightly short so only doing a short stroke on the pump, it was for a different engine.

Havent fitted a new pump or actuator rod and got the wrong one have you?
As many have said mechanical pumps are fine if they are working properly

21 million Beetles can't be wrong.....only worth fitting a leccy pump if a mechanical pump is not practical, as in my case where the updated inlet fanimold is in the way!.....An electric one is far more likely to fail(Imho)......leaving you up shoot creak......(just how many spare parts can we fit in a Buggy).

Agree, mechanical pump for me, unless your carbs' have special needs!  Im told its not uncommon to measure up to 12 psi  from a mechanical pump. As per previous comments: got the right push rod? Pump doesn't have spacers between it and the casing (used to reduce pressure) .

I've been let down too many times in the past by electric pumps on vehicles and machines of all shapes and sizes from Morris Minors to JCBs and CATs. I've got a few of the old rebuildable type original pumps from swapmeets in my shed 'just in case'. Service kits are still available for them.
