I was told they have the same frequencies & was recommended to use the Continental VDO.... No real feedback yet.
As it was only 3/8” pipe,I didn’t want it on my fuel supply. I decided to add a take off on my return line & also went with compression fittings to AN. T from the return line passes through the Flex fuel sensor & returns to tank.
If you have access to good consistent E85 I wouldn't even worry with a flex fuel sensor. Even then if it wasn't a daily driver I would probably just use a decent tester and adjust as necessary. IMHO unless you are on the ragged edge a couple % either way doesn't seem to make any real difference. Just my $0.02
T'd in the return is the only way I recommend running them. In line they can even restrict return flow causing fuel pressure issues at idle. If you are plumbing the system now, as in a fresh fuel system install, take a look at the Power House Racing Flex Fuel Sensor Dual Bypass. Here's the link
We are happy to introduce the PHR Billet High-Flow Dual-Passage Flex Fuel Adapter. This adapter allows for higher volume fuel flow through the flex fuel sensor by allowing a secondary route around the sensor itself. Keeping the flex fuel sensor as the primary direction of flow keeps sensor...
