Hi all.,

Can anyone tell me if a electric fuel pump. controlled by a manual switch. will push fuel thru a mechanical fuel pump on a TR 6 "before" the the mechanical pump , OR would it pull fuel thru better "after" the the mechanical pump to aid in quicker firing the engine off.
Seems like excessive cranking of the engine before the engine fires off relying on the mechanical fuel pump on cold starts. Chokes seem to be adjusted properly but seemingly takes more cranking than necessary to fire off.

Once it fires there is a fairly normal warm up process adjusting the choke until the engine warms up but the initial firing off seems excessive with the mechanical pump only.
Also the electric pump would be a good back up in the event of a mechanical pump failure on a road trip.
Any advice on this ?

Why keep a dog, and bark yourself?

When I purchased my car two years ago it has a electric fuel pump and also the mechanical pump, electric is before manual pump, Before I start the car I turn on the electric fuel pump for a few seconds, then turn it off and it starts up fairly quick without a lot of cranking.

There should be enough gas in the carb bowl to start the car
