Can anyone tell me where to install a electric fuel pump on a 69 Camaro in the rear . I plan on running the exhaust out the rear behind each tire.Any photos would be a big help. This was a last minute decision since I am running a roller cam, and I read the storys about the manual fuel pump fuel rods.Thanks for all the help I sure do not want to mess up this engine.

I have an electric Fuel Pump in my car. I haven't driven the car in 10 months (discussed in another thread) but here is where the fuel pump was relocated to after I had the fuel cell removed & replaced the fuel cell with a sumped gas tank....The car is at the body shop now, but you can mount it along the rear frame rail or right behind the gas tank.
I hope this helps....
P.S. I may have a better pic somewhere else and I will try looking.

I seriously doubt they reccomend mounting that pump transverse. You can mount it to your fuel tank straps with a piece of 1/8" steel with rubber absorbers.

I have redesigned my set up but the theory is the same. I have since changed pumps to a mallory 140 and spaced it out from the mount. I also have the inlet line even with the inlet of the pump. Works flawless.

I'll give you a little advice and it's all from experience. You need to mount the pump inlet lower than the bottom of the tank. Electric fuel pumps need to be gravity fed to work correctly. This is very hard to do with a stock fuel tank sumped or not. The problem you will have is when the fuel level gets low you will lose your prime. If you go to any of the sites of companies that make fuel pumps and read their installation instructions you'll see what I'm saying.
People will tell you it doesn't matter but, it really does make a difference. Electric pumps are designed to push fuel not pull fuel. When you pull fuel from the stock location (out the top of the tank) it can work ok but, you are relying on a syphon to feed the pump fuel and depending on how high (in relation to the fuel) the pump is mounted that will determine how well it will or won't work. In either case once the fuel level gets low you will have fuel supply problems.
Don't forget the use a relay to feed power to the pump. All the people you hear complaining about electric pumps typically don't/didn't follow these basic rules and they have issues and blame it on the pump. When it's the installation that's the problem.
I have run nothing but electric pumps for as long as I can remember and never had an issue with one that was installed correctly. Mounted lower than the fuel supply, filtered inlet, fed by a relay.

Thanks for the advice I have read the same thing you said the inlet end should have a filter and be low as the bottom of the tank.I think I can still mount it the way it is in the photo above.I just don't want it to hang lower than my tank . I am thinking if I get it even with the bottom of the tank? Thanks again for your time and reply.

The rear end housing will protect it. You need to run a 100 micron pre filter then a 10-40 micron down stream before the carb. I put mine before the regulator.

This thread could not have come up at a better time. I'm in the middle of installing a new complete fuel system using an electric fuel pump in my street car. So I have a couple of questions/requests.
Based on Royce's input, I will need to move my pump lower than where it currently resides (pump/input fitting installed even with the bung for the feed line). Your system clearly illustrates what Royce stated.
Can you provide additional pics of your fuel system (filter side would be deal)? I like the idea of using the SS straps with a mild steel plate to hold the pump in place. The fuel tank I'm using is: DSE tank (for carb) with return bung.
Lastly, the radius of the fitting going into the input side of the pump seems tight. I'm assuming that using an 8AN or 10AN fitting such as yours including gravity feed will not be a problem with flow. My system will use a 10AN feed and 8AN return which was similar to what I have on my other Camaro. This all for a GEN6 - BBC application.....
Any additionl input would be welcomed.....
Regards,
Larry
