Has anyone installed this:

to reduce the inaccuracies caused by mounting the fuel flow transducer 

too close to the  boost pump?



I definitely have the problem though it's not really that bad given that 

the boost pump is on only for short periods relative to long cross 

country trips.  The error is in a conservative direction and so far is 

insignificant.



..but I'd still like to reduce the inaccuracy if I can do it without 

relocating the thing.

Bill, we installed it and really did not notice a difference on fuel flow accuracy.  Ultimately the solution was as Robin said to relocate the fuel flow sensor to between the servo and the spider.  Rock solid and accurate since then.



The other thing we notice when using the pulsation dampener was that we started getting low fuel pressure warnings.



Bottom line, we removed it.  It is still on the shelf, if you want to give it a try let me know.



I actually feel kind of bad posting this since Matronics does so much for our RV-10 community.  Others might have had better success, just my experience.



Thanks, Jason
