Simple and functional, that's all it needs be. Good work. -Jason

THIS would be awesome. I've always talked about doing that swap myself, and even spent time in the garage measuring with the two cars next to each other. Someday...

On to the fuel system. I got the fuel tank pulled out of the Chrysler and removed the fuel pump module.



The Chrysler pump module is a 2-piece plastic design where the bottom telescopes in and out of the top, which means it fits the depth of the Fiero tank perfectly. The Chrysler tank is molded plastic and the pump is held into the tank with a large nut that threads onto the tank. It's also about 1 1/2" larger in diameter which means the hole in the tank must be enlarged and a new way to secure the pump designed.



My solution: I had a couple steel rings CNC plasma cut to secure the pump.



Here is how much needs to be trimmed



To get the pump module to fit in the tank, I had to turn the float arm 180deg and install it in this orientation.



The problem was the wiring connector and pump outlet were pointing the wrong way. So by separating the halves of the pump module and turning the top 1 notch over, I was able to get it to point in the right direction.



The rings were drilled and tapped.



I split the lower ring so I could insert it into the tank and held it in place with a flat head bolt.

So here is the Chrysler pump installed in the Fiero tank, bolted in place with the lock ring. I need to make a gasket yet to seal it, and the outlet is too tall and will hit the tunnel, so I will need to build a "dome" into the tunnel to get it to fit.

Very cool...While you have it apart, verify the wiring from the connector to the fuel pump, especially if there is an internal connector. I just had to rework the connector for my Aztek fuel module because the terminals inside the module fret (corrode due to vibration). Simple to fix if you look ahead of time.

There is an internal connector inside the module. But, speaking from experience, there have been no issues with corrosion on those.

The box, you thinking outside it. Nice work on the fuel pump, I was wondering how your were ging to do that. -Jason

Great to see someone thinking outside the box - nice work so far. Looking forward to seeing the finished product.

This is going to be interesting. this motor was what made the prowelr kind of a laughing stock of chrysler. Gorgeous car but lacking in speed due to the weight and setup. i have the same motor in my dads car... real power house per say but the 300M setup is one heavy pig on this motor.. cant wait to see what it does in a lighter setup.

According to 060calculator.com , 250 HP in a 2800lb car should give me a 5.5 second 0-60 time, I'm sure the real world time will be a little higher. What sold me on this swap, power-wise, was a ride in a 3800sc car that was pretty close to stock. I thought it was plenty quick with just enough power to make it a fun ride. Besides, I got size 15 feet, and too much HP underneath them just means more speeding tickets for me.
