Just get a FPR that mounts to the firewall and run the hoses via that. Seriously there really isnt adaptors what you're asking for, either you have one made, make it yourself or figure out other options.

actually there are..... it's generally used to replace the factory regulator, which has a diaphram in it and bolts to the fuel rail.... using an aftermarket fpr with the stock one in place isn't a good idea.... because it won't work.

you can, however, modify the stock fpr to work as an 'adapter'.... pull the stock adapter off and drill a small (smaller than 1/2") hole right in the center.... you want to be able to pull the spring out from the regulator..... doing that allows the diaphram to move freely, and you now need an external regulator to keep the fuel pressure where you want it

There was some Tom's ones on ebay awhile back that were a direct bolt-on in place of factory on the rail, but were pricey. I would follow the above post good idea.
