     Without a fuel pressure gauge you cannot detect the beginnings of a
     fuel flow restriction or failure of a pump until it is too late.  
     According to FAR 23.1305 every engine with a pump should have a fuel
     pressure or flow gauge.  While experimentals aren't bound by FAR 23,
     most of these requirements make good sense.
     
     
     
     Sec. 23.1305 Powerplant instruments.
     The following are required powerplant instruments:
     .......
     (4) For each pump-fed engine, a means:
     (i) That continuously indicates, to the pilot, the fuel pressure or
     fuel flow; or
     (ii) That continuously monitors the fuel system and warns the pilot of
     any fuel flow trend that could lead to engine failure.
