Guys,

Planning on using this to feed the carbs on my Corvair engine....



In terms of wiring, what's the best way to go about it? Connect it to the ignition and control it by its own switch or hook it into the oil pressure switch and use that to control it (which is pretty much what Facet suggest doing)? Only question ive got is that unless Im understanding it wrongly, the pump won't start up until you've cranked the engine enough to put the oil pressure light out. I'm thinking thats perhaps not a bad thing, but again, could someone confirm?

Thanks guys.

Correct.........you can wire in a prime button as well.........

In this pic the alternator light is used, but either will do......this is how I wired mine........

not that Im very good at this stuff as you know, but I have the same pump, I have mine wired up to its own switch, or at least Chad did the wiring  :D
The reason I wanted it like this (it was wired up to the ignition when I got the buggy) was so that I could turn the ignition on if I wanted to use something else, radio etc etc, without the pump starting up at the same time, I have a start button as well since I dont have it all on the steering stork.

I'm sure Chad has wired it well but in general,  ;-)up people should not leave the ignition turned on whilst listening to a radio or something because it can burn the coil out if that is turned on at the same time

........I just piggy backed off the idiot light, keeping all wiring up front........but I suppose it depends wether you're fitting the pump near the tank, and of course where your tank infact is....
Pump only works when engine runs, so no worries with ignition, handy when fiddling with electrics too. And when you've stove it into something, and its sat upside down, hopefully stalled.........you wont be pumping fuel everywhere.

run my one in the split oval earth to bodywork and poss to poss on coil, that way its only live when ignition is on, i can hear it run before i fire engine up and it acts as a back up noise to remind me ignition is on, they can be a bit loud and dont tend to last the best given they cost 50 quid ish, ive done 3 pumps in 3 yrs on 2 cars...
id fit close to carb so they have less work to do might prolong life

According to facet it should be as close to the tank as possable because it pushes fuel and need gravity to feed fuel to the pump.

Easy to Install: Two-bolt installation plus the small size makes installation easy. For best results, mount the pump close to the fluid or fuel tank and below the liquid level.

mines about a foot and a half under my tank, so that should work ...I hope   ::)

the facet fitting instruction is aimed at normal cars where the tank is low mounted so fuel needs raising to the motor in a buggy/beetle the tank is high and leaving the 6mm pipe open at the rear will empty the tank faster that the pump will use it for the engine and that is gravity/surface pressure in the tank.
mount a pump in the rear lower than the tank my last facet did 7 years daily use about 6ft away from the tank.
shorter pressurised lines = less chance of a leak/failure
