Electrical fuel pump question

I'm looking around to buy an electrical fuel pump, what capacity should I look for, is it the gallons per hour or the psi... At Carquest, I'd pay around 60$CAN for a 5 psi...

Also, what should I wire it to... where under the under can I find a wire with power when the key is turned on ? I know I sound a little basic this morning, it's because I had to many beers last night, and I'm in really bad shape today...

Ha - I looked under my under and I didn't see any wires. [img]/wwwthreads_images/icons/wink.gif[/img]

Sorry, man, just giving you sh|t for being hungover. Man, I hate days like that. [img]/wwwthreads_images/icons/crazy.gif[/img]

5 PSI should be fine. I don't think you have to worry about higher Gallons per minute, or anything like that until you get up into racing motors, so you should be ok with the generic type, I would think.

As I understand it, carbureted systems typically run up to about 6 PSI.

Good luck

Re: Electrical fuel pump question

vapor lock is basically when you've got a fuel line running next to something really hot (like the exhaust). What sometimes happens is the liquid gasoline will actually vaporize, turning into gas. When this occurs, the fuel pump is trying to pump gas (i.e. not liquid), which compresses and the motor can't get enough fuel.
