I never would never wire the on/off switch like that.it should be wired underneath the dash. Not sure who your replying to... If it was this reply, maybe you should read what he said. 70HemiGTX I have mine mounted on the inside of the rear frame rails along side the fuel cell. I have filters mounted to the rear frame crossmember between the cell and pumps. As you can see the pumps are lower than the cell, so I have gravity feed. I have the relays inside the trunk and run the main feed off the battery cut-off switch. I have the switches in the dash and plummed through the oil pressure cut-out switch (Holley if I remember correctly). It only takes about a 3 amp fuse for at the switches. Wire it as safely as you possibly can! If you're referring to the switch in the pic it's a battery disconnect which is required at the track if you have a trunk mounted battery. From your replies, You just might be better off paying someone who actually knows what they're doing to work on your car.

Ok i know people who still have that switch by there dash frame to. Then you know people who don't know how to properly wire things on a car. Copying them would be a very bad idea, unless you want to show us how Darwinism really works.

Just mount it near the fuel tank like everyone said already All cars and exhaust systems are different so you will have to figure the best place for your application. I mounted mine on the right rear frame rail but if you have a full exhaust that might not work for you. Gus

Did you Google images of this project? There are hundreds of pictures showing how to mount them.

All wire-cables should be as short as possible when carring a lot of amps, wire that pump to a regular starter relay, mounted in the trunk, then just run a ground wire to the dash switch, no amps, no power loss. I put my pump-pumps-filter behind the fuel cell or tank on RACE cars, If just going to shows, a regular engine fuel pump will be enough, why a noisy electric?

I need a electric pump givin it gas at all times.i tried a regular pump,couldn't get no gas anymore goin to carb.the Pump was new as well. i had to put a air compressor hose down the tank with compressor on to give it gas at all times.l like the sound of a electric pump. Im running a 850 demon mighty carb to.they need alot of gas,so it doesn't starve for fuel. Not being rude but you got big problems somewhere, the NASCAR guys used a mechanical pump and ran 200 mph on 800 hp engines, never had a problem keeping their carb full.

Bolt a plate big enough to hold the fuel pump to the frame rail in a safe location between the rear axle and the tank. You can power the fuel pump through an ignition hot power source, but it won't run the pump until the ignition switch is in the rum position. That is the way I run mine. Powered this way, the pump will run whenever the key is in the run position. If you wreck the car, turn off the ignition switch. If you set the power source up with a relay and ground the relay through the oil pressure switch, the pump won't run until the motor has oil pressure, and it won't run if you loose oil pressure, a pretty good safety feature.
Mount the pump so it is below the fuel line coming out of the tank, then have the electric fuel pump mount mounted so that then inlet (coming from the tank) on the pump is slightly below the level of the outlet. What this will do is assure the inlet is covered with fuel as soon as it is turned on. If there is fuel the pump can pick up, having fuel at the inlet upon powering the pump will allow the pump to pull the fuel into the pump. A pump without defects will last a long time. Gene
