No fuel return to tank on V70????

I have a 1998 V70 and cannot find a fuel return from the injector rail to the tank!

There is a device on the injector rail that looks like a pressure regulator and is in the same spot as the regulator on my other car [an 850] but there is no pipe coming from it.

I thought the problem with no return to the tank was a possibility of vapour blocks caused by fuel vapourising? Also, the fuel runs hotter?

Also, how is the pressure regulated if there is no obvious regulator + return?

I would be grateful is someone can explain what is happening on the V70 [non-turbo] fuel system.

Best Regards,

Dave
