Just wanted some feedback or personal opinions on what is the better of the two. I have a mechanical pump right now, but wanted to see if there are any advantages and of course any disadvantages to changing over to an electric fuel pump. Then if I were to change, what specs am I looking for in a elec pump?
ALSO: Where's the best place to mount an elec pump? Front/Middle/Rear?
Thanks & Aloha,

If your motor is the stock 305 and everything is working just fine, why would you want to change it...there's no reason to do so.

The motor in my elky is a 350. Has an after market cam, edelbrock 1405 carb(600 cfm w/man choke), long headers, HEI...

If it doesn't run out of fuel when you hold it wide open through the gears - as theelcaminofactory said - why change it?

I'm running pretty much the same set up, except roller cam and cam gears. Hooked to a 350 turbo with shift kit.

I'm using both. Replaced the mechanical pump with a higher output (and chrome plated) and added an electric pump at the tank.

No real difference, I never had a "flat spot" because the factory pump was not feeding fuel, but I just like the sound of the electric pump building up pressure in the fuel line.

If you decide on adding an electric pump, place it as close as you can to the tank. They are designed to push fuel, not pull it.

Stock type mechanical fuel pump will be fine for your application. If you do decide to upgrade. Watch fuel pressure ratings on the pump. If you get much over 5 PSI you may need to add a regulator to the system.

The stock mechanical pump should be fine, but the advantages of having an electrcal pump are not having just a rubber diaphram separating your engine oil and the gasoline supply plus if you only drive your elky occasionally its nice to be able to fill the float bowl in the carb without having to crank the engine forever----much more starter friendly---so the answer is it depends on how you drive your car................Dan

My friend's VW has a short in the electric system. Some little gremlin, well his electric fuel pump goes out sometimes and he dosen't enjoy that one bit. :(

I will keep it really simple they do not make mechanical fuel pumps for cars made in the past twenty years. Reasons why all cars made today have electric fuel pumps, they keep better fuel pressure and can be controled by computers allowing more presise control, also they put them in the tank now wich give it better pressure being closer to the fuel. Old mechanical pumps decrease fuel pressure over the years, you want at least 5psi, but you can go up to 7psi on most stock apps. I would rather have that extra pressure for those all out throttle situation, last thing you want is fuel starvation, another thing is GPH (gallons per hour) this can effect hi performance or super charged engines , but most stock cars dont need a high flow pump mine is a low 97 GPH and has a 6-7 psi no regulator required, any higher psi and you have to by a pressure regulator. If you install a fuel pump get an inline one mount it below your gas tank with rubber washers to reduce noise, use steel braided fuel line if possible, I recommend removing at least the mechanical rod, or the whole unit and use a nice chrome cover plate.
My electric fuel pump I have works great, with built in filter it was 80$ now working for over two years. Worse part of electric fuel pumps is they can buzz chatter when low on fuel, some have different designs for running more quite. More electric parts reduce static friction from moving parts like a mechanical fuel pump, or a mechanical water pump vs electric. It comes down to this there are a lot of electric fuel pumps out there and a big difference between street and race pumps you want a street pump for your application, a race pump is what you dont want.
These can be expensive conversions, and benifits are minimal, but some steps are small with a larger over all goal in mind.
