thanks for the parts list Todd. very helpful. 

Tech said the 165 unit recommendation was to compensate for the 30’ pull from the tank. I  posted this to you guys to get thoughts/feedback before ordering one. I real appreciate your feedback 

Good morning guys,
Well my lift pump is leaking. (2001 Diplomate LE) I have read several posts here as well as other forums. (As many have stated the information you guys provide is invaluable). I have talked to FASS (knowledgeable tech named Scott). They have a new product (introduced in latter 2021) designed for “industrial” applications which list motorhomes as one of the applications. Scott recommended the “FASS Industrial Series 165GPH Diesel Fuel System”. The description states, “our Industrial Series Diesel Fuel System eliminates the need to purchase and install a dedicated fuel return line kit.” I expressed my concern (grilled him) on everything I have read on the need for running a dedicated return line (potential pressure differential ect). Scott was very patient/professional in explaining the engineering of this product line. It uses a ¼ inch return output that T’s into our existing ½” return. Another difference is the 1 million mile or 5 yr warranty. This product is designed for non-pickup truck applications where a long-dedicated return was needed. 
I’ll install a gauge sending unit on the secondary filter tap and run output to a dash pressure gauge. 
Probably install 6 port fuse block in battery bay.  i'm hoping to find an ignition wire source at the tow plug.

I’m trying to compile my material list in hopes of ordering everything upfront prior to starting the install.  I’m a little fuzzy on fitting sizes. 
Do any of you remember the size of the plugs that screw into the oem pump once the hoses are rerouted? 
What size fitting quarter-turn ball valve to the INLET of FASS for changing filters?
What relay do I order to plug into the oem lift pump connector? 
Thanks

This is the razor blade that works. The orange blades in bulk were crap. I had to order several of this one.

I removed mine on our 2001 dip le a few years  ago. I purchased a steam wall paper remover, a good adhesive remover and orange plastic razor blades. I broke it up into probably 5 sessions. Once I got the hang of it it was easy work. You just take your time. It turned out really well with no paint damage. Happy to provide product links for anyone interested.

Before and after 

I installed the Source kit on my 2001 Diplomat LE. Definitely worth the money. 

There’s a good YouTube video on the filter change. 

I had the same symptom last month on our way home. Changed the fuel filter runs fine now.
