            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.     .......
