HHR Ed Posted October 5, 2010 Report Share Posted October 5, 2010 shouldnt matter. There will be some minimal vibration on the pump parts, but should affect it unless you are in the mid to high 160dB range. Which I doubt you will be.

STEvil Posted October 5, 2010 Report Share Posted October 5, 2010 If you manage to get air bubbles in the lift pump (by frothing the fuel due to flex) there may be a cavitation issue caused, but other than that you'll be fine. On an interesting note, the engines in the 1958 MGA Twin Cam's had a resonance issue which caused the fuel to burn "lean" at certain RPM's... in short they killed engines easy The article sucks btw, but this bit of it does bring up an interesting thought. http://www.time.com/time/specials/2007/article/0,28804,1658545_1657867_1657786,00.html MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Peterpanels Posted October 5, 2010 Author Report Share Posted October 5, 2010 Thanks for the advice guys, nice article too. Mg make a nice looking car but crap engines. I never thought Acoustic resonance could destroy a motor, very interesting. I have a cast iron block so I'm good there. I was a little worried about all the slushing of fuel and how the car would smell with the system cranked and fuel breather pipes working overtime.
