Now that my conversion is over 3 years old, I am going through and re-working some things that I could have done better. The first thing is my fuel pump. I am using an el-cheapo pump that is mounted in the engine compartment down low where the fuel lines come out of the firewall. I was using a Holley Red, but it was so noisy and it died anyway.
The reason for the rework is that the pump sometimes seems to go dry, espescially after driving on the freeway for a while and after sitting, espescially when its hot. I think its a case of fuel starvation and vapor lock. I am planning on moving the pump to the front trunk area, closer to the tank. What else is everyone doing? I also would like to find a quiet pump. My car is a 72, so there was not a pump in the front to begin with, that's why I started with the pump in the rear. The other thing I am getting ready to re do is my cooling system. I just had a 14x27 dual pass two 1.5 inch core radiator fabricated by a local hot rod shop for $275. The owner said this radiator should be able to cool a big-block with 1800CFM. Alot cheaper than those other places. Thanks Mark |

I recently posted information about my V8 conversion: V8 Conversion.
I used a Carter pump located next for the old heater duct. It is also rather noisy. I am going to either isolate it better, or wrap it with an acoustic treatment, or both. I also replaced the plastic fuel line with a 3/8" steel tube - I used brake line tubing for this. I don't seem to have any problems with it and it seems to be able to pump a very large volume when needed. I installed a fuel filter in the forward compartment (in the location of the original fuel pump) and I installed another filter in the engine compartment after the fuel pump. I used mostly 3/8" fuel line to keep friction losses to a minimum. Attached image(s) |
