John,

Below you mention using = =93small Earl's in-line filters = with the conical (brass?) filter blocks.=94=A0 These sound like = the sintered bronze filters that Tracy recommends not using as they = become blocked more easily than mesh screens.=A0 The sintered = bronze is also hard to see if blocked, which it sounds like you = experienced.=A0=A0

Earl=92s has one type of filter that comes in either = sintered bronze or stainless steel mesh (field cleanable).=A0 Here=92s a link = that describes the stainless steel mesh version: =A0

[FlyRotary] Earls = in-line fuel filters

=A0I've been having fuel flow problems on = one side for a while.

Runup would give me = full static on either pump. I take off on = both.=A0

Some time later in the = flight here's what happens:

=A0=A0=A0 I switch on = the right pump (which feeds from a separate tank), mixture comes back = up=A0and engine runs normally.

=A0

I have the small Earl's in-line filters = with the conical (brass?) filter blocks. They always "look" clean when I = take them apart, but yesterday I tried blowing through them.

I think I'll get larger canister type = filters with a=A0drain like Buly's. Buly - where did you get those? Got = a part number?

Anyone else have a = filter part number they can suggest?
