RobertGM2 Posted April 17, 2007 Share Posted April 17, 2007 Hi gang. I'm trying to put together an early 60's style fuel altered but I'm having a hard time finding photos or articles that show how to plumb and wire the car. I want help setting up the fuel lines especially. Any suggestions? Quote Link to comment Share on other sites More sharing options...

RobertGM2 Posted April 18, 2007 Author Share Posted April 18, 2007 I'm using the blown Hemi from the Winged Express, with a moon tank. I'm sure about the fuel pump. Quote Link to comment Share on other sites More sharing options...
Jairus Posted April 18, 2007 Share Posted April 18, 2007 Since you said you understand the fuel pump we will talk only about the upper portion of the fuel lines on a 60's blown engine. The basics are the same for all engines, street, drag or whatever. But the hardware can vary widely due to equipment used. Fuel is pumped one direction into the engine. Sometimes there are two lines (A). In those cases, one is usually the return line. Fuel is under pressure at all times but that varies when the engine rpm's change. In order to maintain that pressure a valve is installed that maintains a consistent volume and bleeds off the excess which returns to the pump or to the tank. This is also why there may be two lines between the tank and the pump. To meter the fuel/air for throttle control, a fuel block with a metering valve ( is attached to the side of the "Hat/scoop" and controlled by adjustable control rods (E). As the butterflies open and close with the throttle the fuel valve is opened and closed like a water faucet. The metered fuel is distributed to the injectors via rubber or aircraft hoses. Most 60's dragsters used rubber hoses or steel lines. The aircraft hoses that are so commonplace now, were very expensive having been developed for the Apollo space program had not yet been adopted by the sport until the later 70's. There are two hoses © generally, because injectors can be located above and below the blower. If only one set of injectors are used under the scoop then there would be only one hose between the metering block and the distribution block. At the back of the blower is located one or two distribution blocks (D) where the fuel is broken up into individual lines for each injector. Some systems use only 4 and some as many as 16 injectors! Some systems have these pieces located in different positions but the basics are the same. The illustration shown is the pretty much the basic AMT or Revell blown funny car or dragster Hemi engine.
