I'd like to have my fuel hoses pressure tested for a possible air leak. I replaced all hoses 2 years ago but have had fluctuating fuel flow on climb out for about the same amount of time since the hoses were replaced. In the interim I've had the fuel system overhauled twice and the fuel selector resealed all without resolution.
The fuel flow fluctuates during high power settings in the climb and is in the 1/2 GPH range. I had one event where after rotation the fluctuation was from the normal 25 GPH to as low as 18 GPH in the first 1000'. On another occasion it was a pretty high frequency of fluctuation but in the 1/2 GPH range. The 2 mentioned events both involved a long idle time waiting for clearance in hot summer weather although the 1/2 GPH is on every climb out. It smoothes out in cruise and when RPM's are reduced from 2500 to 2325 (my normal cruise setting).
Any input is appreciated and if there is a "best source" for pressure testing I'd be grateful for a suggestion.
