I am thinking about converting my 68 coupe 302 to electric fuel pump.What all do I need for the switch? Or is this a bad move?
I am running a 1 year old 4160 holly 600..Will I need a regulator for this or can I just run a inline electric fuel pump straight to the carb?Hi,
Bad move? Not really, as they tend to assist with reducing any vapor lock tendencies and remove clutter in the engine bay. I would recommend an inertia switch in case of an collision as they shut off power to the pump. Most all electric pumps should be mounted in the back. Mine is mounted on the bulkhead just on the forward side of the tank. (see pics)
Be mindful, you'll may need a regulator, as most carbs don't like more than 5-7 lbs. Some pumps are preset at this rating, others are much higher and need the regulator. If your running an Eddy carb, PM me as I may have some parts you can use as I went from an eddy and Holly to the DCOEs.
As I mentioned, in part, most all street Hollys don't like more than 7 lbs. psi max.I am running a 1 year old 4160 holly 600..Will I need a regulator for this or can I just run a inline electric fuel pump straight to the carb?
Got it.Thanks for the info.As I mentioned, in part, most all street Hollys don't like more than 7 lbs. psi max.
It's the output specs of the pump that needs to be considered. If it's output is greater than 7, yes, you will need a regulator. Otherwise, the excessive pressure will push the float seats open and you begin flooding the engine. Most all if not all popular electric pumps will have their specs very evident.
Hope this is more clear.
Agreed. I put an electric pump on one of my cars years ago, and hated it. Unless you have something that is keepin you from running a mech. pump, I wouldn't recommend it.FOr a street car I would recomend a mechanical pump. The noise is going to be anoying, and the hp gain will be very minimal if any.
Also a mechanical pump is very reliable, electric pump just introduces more things to break down and more fittings that can leak.
Save the electric pumps for race cars that need the few extra gallons of output
