Fuel injection

[Aston Dbs Viper]

Hi all in the USA.
I'm Phil here in Devon, England and I have a customer that has an Aston Martin Dbs 1968 with a 2005 Srt10 engine and box fitted it had no electrics or fuel delivery system yet but you guys may be able to help.
We will be running the Aston tank so need a different fuel pump. The standard system runs at 55psi has anyone fitted an after market pump? What was it and where can I get one.
Secondly, I can't find the return from the fuel Injection system? Where does it come from?
Many thanks
Phil

The Viper uses a returnless fuel system with the pressure regulator made into the in-tank fuel pump assembly. I would get in contact with Dan at Viper Specialty Performance as I think he has been involved with several transplants in the past.
