Dual fuel, old school
 

This is the latest stage in this fuel upgrade, using a modified carb-type fuel block to feed the rails. Room is scarce even though the FPR can be located anywhere, braided hose got to be too bulky to deal with. This setup is different in that I routed the fuel through the FPR. The 1/8 pipe tap is not all that restrictive compared to a 6AN hose fitting, but better flowing would be a T-fitting to replace the brass bushing between the FPR and fuel block. That would place the FPR to the side and run the main fuel line directly to the fuel block. Downside to that is, adapters are needed for the T-fitting, requiring more room. The FPR could be tapped for a 3/8 pipe outlet, but I dont think it's necessary. There are only 2 hose clamps involved, and the short rubber hose pieces provide a bit of flexibility, isolate from vibration.

awesome! looks good man!

Thanks, I wish I was better at routing wires, though :)

Cool man.

Looks pretty clean wire wise

i have that same FPR, its a tight squeeze between that fuel rail and intake manifold.
