Fuel Rail modification

Now the cooling circuit has been installed, progress towards the completed engine installation gateway moves ever closer. Need to refocus energies back on fuel circuit.

Previous posts will have made reference to the fuel system, swirl pot etc the final piece to complete is running fuel lines from the HP pump to the fuel rail and from the swirl pot to the fuel regulator at other end of the fuel rail.   

In regards to the fuel regulator, reading the GBS owners forum, it is suggested the OEM Ford regulator is more than adequate for the build and although the GBS fuel system comes with an adjustable fuel pressure regulator it is not essential to replace the OEM one with the adjustable version (need to return that..!)

So basing my decision on better peoples knowledge I elected to keep the Ford regulator.

One piece which does need replacing is what can be best described as the twisty return pipe which comes out of the other end of the fuel rail. Some builders have bent this round and cut off leaving a short piece protruding onto which the fuel hose connects. GBS do sell their own adapter which replaces the OEM part - not being overly expensive and personally I think looks better I switched the OEM part for the GBS version.


Final comment, GBS suggest switching the fuel regulator round with the adapter, however when I did this i noted the regulator blocks a wiring loom plug so decided to leave as per the original layout (regulator facing the front of the car, adapter facing the firewall)

So, build wise its simply a case of removing the "twisty return pipe" and replacing with the GBS adapter!
