Edelbrock has reintroduced the vintage cast aluminum fuel blocks for dual, triple and quad carb applications for your hot rod or custom vehicle. Edelbrock fire wall mounted fuel blocks feature a single 3/8" NPT inlet and two, three or four 1/4" NPT outlets, depending on application. Each fuel block has four holes for mounting to a fire wall and are available with a satin aluminum or polished finish. Triple fuel blocks can also be used with any dual carb installation by blocking off the unused outlet with pipe plug #662043 or any similar 1/4" -18 NPT plug. The third outlet can also be run to fuel pressure gauge if desired.
