With properly treated fuel I wouldn't worry about it but a filter wrap isn't the worst idea either.



The original S&S return filter kit used a Racor SNAPP filter, they swapped that out for a 9 micron Donaldson spin on I believe due to availability of the snapp filters. IMHO 10-20 microns is plenty for return line filtration.

If the top filter gelled up, so would the S&S filter sitting next to it but more exposed, so the back pressure on the system would cause the engine to run extremely bad at which point, shut if off.

Properly treated fuel shouldn't gel or get algae. On the flip side, that window in the new kit allows one to see the fuel condition as well. A real quick look will tell if the fuel is gelling or if there is a squid being born.

I monitor pressure of the DFCM (primary pump) on my iDash with the factory dual fuel temp/pressure sensor under the hood... at one point i will replace it as i have two SNAPP marine version filters, the housing is white.

Here's my thought on it. The S&S may keep the tank clean when the CP4 fails, but how longer before complete failure on the side of the road if there is no way to check without pulling and cutting open the filter? How long does it take to grind down the cam before it turns into fines that can get past the 20 micron screen before the cut off is triggered? If damage happens to the CP4, the first things coming out of it will be chunks of plating from the can, which will get caught by the screen and visible. So it is an early warning system, then if ignored will become a potential issue beyond.

I'm tossing the SPE vs S&S kits as my next install. I see many pros with the gen 2 kit in that is looks factory, and uses factory mounting points, and is all hard lines. They even have the return set up so no twisting of fittings, and installation is much easier and faster now.

The main pro of the S&S is the return filter, but uses hoses and I think cutting has been eliminated, but does take longer to install. It also costs more now.

Lets hear your thoughts on both kits.
