Is there a way to allow customers from two separate VRF to transfer data between them .both vrf are on the same7609 PE router.

yes its possible, doing a regular import export between both the VRF's. (extranet)
Routes from the other VRF would be having a VPN-route-head tag information set for switching between the VRF's in CEF.

Hi,
in case you have a MPLS VPN and thus MP-BGP the config is rather simple, f.e.
ip vrf Customer1
rd 65000:1
route-target import 65000:102
route-target export 65000:102
ip vrf Customer2
rd 65000:2
route-target import 65000:102
route-target export 65000:102
In case you are using VRF-Lite (aka Multi-VRF) you would be able to get the result through packet leaking:
ip vrf Customer1
rd 65000:1
interface Serial1
ip vrf forwarding Customer1
ip address ...
ip vrf Customer2
rd 65000:2
interface Serial2
ip vrf forwarding Customer2
ip address ...
ip route vrf Customer1 10.2.0.0 255.255.0.0 Serial2
ip route vrf Customer2 10.1.0.0 255.255.0.0 Serial1
This will copy the IP packets between the VRFs. You will need to adjust all the numbers and names in the example above to your environment.
Hope this helps! Please rate all posts.

Is that a new feature in the ios? Because in the following link:
http://www.cisco.com/en/US/tech/tk436/tk832/technologies_configuration_example09186a0080231a3e.shtml
They said: "You can not configure two static routes to advertise each prefix between the VRFs, because this method is not supported?packets will not be routed by the router. To achieve route leaking between VRFs, you must use the import functionality of route-target and enable Border Gateway Protocol (BGP) on the router. No BGP neighbor is required."
Best regards
