Message: [QUOTE="old man dave, post: 48948, member: 1009"] You can use larger lines by adapting the fuel rail plugs at the back of the heads for AN-6 lines. My buddy cut off the pipe threads on AN-6/1/4NPT fittings, brazed them to the fuel rail plugs and drilled through the modified adaptor fitting and fuel rail plug. These plugs are o-ring seal so they don't need to be torqued a lot to seal. Aeroquip makes an AN-6/1/4NPT close bend fitting that just clears the firewall but I don't recall what the part number is, the other bend fittings for AN-6 lines are wide bends that do not clear the firewall. I also don't like the hard 90* fittings. If you use 3/8" pushlock hose then the close bend fittings also fit. The AN-6/fuel rail plug is also sold by DI at a price probably cheaper than you can make it. I just plugged the original fuel orifices in the heads with 1/8" NPT plugs. One is included in Bean's fuel system that I installed but I wanted both sides fed with AN-6 sized lines. As far as damaging the small hard lines at the back of the heads goes, one day while I was Sawz-Alling out my old downpipe...... [/QUOTE]
