Electric fuel pump location
I note that many people site the electric fuel pump near the tank. Any reason why this shouldn't be in the engine bay? Fitting a pair of
Dellortos and therefor 'going electric'. Easier to take a power supply from under the bonnet.

most pumps are designed to have a short pull and a long throw. putting them closer to the tank makes it easier for the pump to "pull" the
fuel before "Throwing" it downt he fuel lines into the engine bay.
If your going Carbs remember you may need a fuel pressure regulator.

Mounting close to the tank and low down avoids vapour locks forming in the suction side of the pump.

Yup, they blow better than they suck, it's easier to blow through long runs of pipe than suck so much better to run the high pressure side the
furthest.

You can get low presure sucking pumps that are perfect for webers and are designed to sit in the engine bay. Brand name Huco as sold by webcon. Mine
fills my swirl pot in the engine bay. For carbs you dont need any extra regulators.

I ran a Huco suction pump in my engine bay and any prolonged high rev driving and the engine would die, thought it was a dodgy fuel line so replaced
it all... still happened, when engine cut out the pump would be going flat out trying to fill the float bowls, pinto on 40s and not running rich. prob
solved with a red top on the chassis rail in the bay at the same level as the sender unit and filter king on the wing.
