Greetings

I am about to install a 440 with EFI into an 85 Dodge D100. Does anyone have any suggestions on where to mount the fuel pump for the EFI?

Thanks

Most will tell you it should be mounted in the tank. I mounted mine on the frame rail close to the tank, 8 plus years no problems.
Make sure you place the fuel regulator after the injectors, and on the return line to the tank.

Thanks Vertman

I've heard some complain about the noise from them mounted on frame. I don't think I'd care but

At least on frame it's away from heat of engine. Didn't go well for me mounted in engine compartment and I'm sure heat played a factor but quality of pump may have as well. My opinion is if there's a tank available for you application that you can submerse the pump in that's best and worth it but at least a quality pump away from engine is good if you don't mind the noise.

For years I ran an electric pump on all my old Mopars, carbed or EFI (started running electric pumps in the late 70s). I always hung the pump on the frame rail just in front of the rear axle, tilted at a slight angle with the fuel outlet up a bit higher then the inlet, and the line for the inlet dipped down to the pump. That way, the pump always had fuel in it on startup. I could hear the pump run at first start up on the carbed motors until the float bowl was filled, then it was pretty quite. I turned on the key to power the pump before any attempt to start, once the float bowl was full, they always started right up. I ran the cheap fuel pumps ($30 range back then, probably a lot higher now) and put 1000s of miles on them and never had to replace one on any vehicle I put an electric pump on. With the motor running, you had to listen real hard to hear the pump.
