Are there any disadvantages for mounting fuel pump in engine bay ?

My pump at the rear is a low pressure unit for the simple reason I have joints - rubber to copper pipe - on the fuel line to engine bay and these joints are in the prop-shaft tunnel. Reason is to have little pressure in pipe to prevent leaks or failure at these joints (double clamped) that may result in me being BBQ..
The low pressure pump deliver to an engine bay fitted swirl tank and from there the high pressure pump, fitted close to swirl tank, with fancy braided hoses and shiny fittings take over to deliver to injectors manifold. The return pipe from the swirl tank to the fuel tank keep pressure out of the system from tank to swirl pot minimizing leak risks. Last edited by Wynand : 28th June 2012 at 09:03 AM.

I'll have one low pressure pump for carbed ZX9R engine... so I plan to use as much as I can of OEM engine/bike loom.
I know it's only one or two more wires, but less complicated is better
