Best one is an Andair, not cheap though. The old Mini gascolator is too sma
ll for a 914, GAS375 would be the one=0A=0AGraham=0A=0A=0A=0A______________

chatting with Rob Seaton ( of Rotech in canada). He said he learned how to
o small a fuel line and/or tortured routing can cause "cavitation" at the p
umps. So maybe your fuel filter(s), on the suction side of the pump,are cau
sing cavitation in the pump(s). Maybe due to the size (restriction of flow)
of the filter, even if they are clean.=0A........ Snip=0A=0AKevin, I think
Rob Seaton may be on the money with this one.=C2- =0AA year or so back,
I experienced a dead cut while flying a friend's 914 powered Europa on a ho
t day. Nifty application of fuel pump restored the noise, but once safely b
ack on the ground, I checked the filters (all clean). This aircraft was fit
ted with Europa specified Purolator glass shrouded filters that allow you t
o see the fuel flowing. At low RPM, the filter appeared full, but as power
was increased, the filter began to fill with what I thought was air. My fir
st action was to check the pipework and security of connections - but every
thing seemed fine - it was definitely not drawing in air from anywhere. I t
hen concluded that I had experienced vapour lock and left it at that.=0A=0A
Curiosity got the better of me and I started researching cavitation and stu
mbled upon this very stilted, but interesting presentation on Youtube. Take
a look at the first minute from 00.20 - in particular, the glass venturi.
This was exactly what I saw in the Purolator filters.=0A=0Ahttp://www.youtu
be.com/watch?v=K_w3gcvA87I=0A=0AMy conclusion is that the Purolator filte
r has the correct mesh size to trap contaminants, but the filter capacity i
s too small and creates a pressure drop in the fuel line.=0A=0ANigel=0Ahttp
