Electric Fuel Pump Placement

My understanding is that pumps tend to push better then they pull.  So, the closer to the tank, the better.  A good second would be along the frame rail, where siphon helps feed the pump.  Up near the engine is a bad idea. 

 

Also be sure that the pressure is not too high for your carb.  Look in your service manual to see what the mechanical pump would produce - that is what you need from a modern unit, plus maybe a smidge higher for distance traveled.

I plan on placing the pump at the rear with an adjustable regulator at the front. I purchased the pump from classicbuicks.com . Mostly curious where others have placed theirs specifically. Thanks in advance!

Always as close to the tank outlet as possible since vapor lock occurs on the suction side of any pump.  Use 12-14 ga wire.  I have a toggle switch to activate mine as needed, since I am pumping through the mechanical (yours may be different).  If using full time you need this:  http://www.summitracing.com/parts/rfw-cr92/overview/  ...avoids you and your car becoming a 'crispy critter'.

So do you recommend using the original pump over an electric one? Sounds like your car is set up just to fill the line and then run off the mechanical, right?

Right, fill the line and carb if it has been sitting for a few days AND to correct vapor lock or in anticipation of vapor lock.  Not all electric pumps will allow fuel to be pulled through them; if yours does not allow, just loop around the pump with a check valve.  There is not much info on the one you ordered, but if it is like this one (http://www.summitracing.com/parts/atx-e8012s?seid=srese1&gclid=COHu-JWb28UCFQ-SaQodgEUARg), send it back...those Airtex pumps are junk and will fail when you need them the most.  This is the one I use now (http://www.summitracing.com/parts/CRT-P60504) with a loop and check valve.

Damn that looks like the onei got... except I paid almost $80 for it. Well I can attempt to try the old pump but it's been sitting out of the car for more than 30 years. Any kits that are ethanol friendly?
