I recently installed the sinister regulated return fuel system on my 01 7.3L and it's starting to get cold, started having cold start issues. I realized its because when I installed the new system, I also deleted the OEM fuel bowl and fuel heater inside the housing, has anyone found an aftermarket heating system?

So what I did was used wix fuel manager filter assemblies WIX Filters - 24912 Heavy Duty Fuel Manager Assembly with a WIX Filters - 24922 Heavy Duty Heater Kit. I have 2 of these filters in my system one is 30 microns and the outer is finish filter 2 to 5 microns. So far I have not had any troubles with just the one but I can add a second heater element if I need to.

how cold does it get where you are? i have not had fuel bowl heaters on any of my trucks in forever and have never had any problems with fuel gelling down to -10 degrees.

It's been down to low 20s, but ya ever since I installed it she wont start when its below 40 without tryin to start 2 or 3 times but today was in the 20s and took a good 5 minutes to get started. Glow plugs work, engine has never been chipped or programmed. My block heater is bad and I haven't ordered one yet.

Where did you mount your filters, and what fuel pressure are you running? With my regulator I am running 65-70psi.

how do you know the glow plugs are working??? if you are going by the Wait To Start light in the dash, that is just an idiot light that will come on whether the glow plugs are working or not.
i put a small light bulb or led in the dash connected to the output of the glow plug relay to see if the relay is working or not. the WTS in the dash comes on for around 15 seconds and then goes out. the led will stay lit for up to 3 minutes depending on outside temperature showing power is going to the glow plugs.
mt bet is your glow plug relay has failed and the glow plugs are not working.

I bet at least a few GPS are bad.
I had the filters mounted outboard of the frame rail, seen below 0 myself quite a bit. Never a problem.
Before the efuel, I had the heater unplugged for a long time.

I have a Snap-on diagnostic tool, and I have ran a glow plug relay test and they are new plugs, I just didnt test them.

Mine is mounted inboard just in front of the front tank. there is pics in my build thread link in my sig below. I have a metal custom rear tank and I had some gelling issues in the past is the only reason I added a heater it only runs if the fuel is below a certain temp. Are the glow plugs motorcraft if not They have probably started failing. if the glow plugs are working then the engine should fire. I mean my heater takes a while before the heated fuel gets to the injectors. and once the motor is running it will heat the fuel in the block and send warm fuel back to the tank to warm the tank. so the heater is just incase not even used once the engine runs for a little bit. that and it takes a while to heat 40 gallons.

yank them out the autolites will swell and break off. mine lasted less then 3 months only use motorcraft glowplugs or you will regret it. I would change them before I worry bout a fuel heater.

autolites. ICK!!!!
i can not understand why they are still allowed to sell that garbage.
GET THEM OUT QUICK!!!
i have never seen an autocrap glow plug work more than 2-3 starts. most burn out after the first start.
champion, welllman, bosch, diesel rx, and all the other aftermarket glow -lugs are almost as bad as autocrap plugs are.

motorcraft ZD-11 glow plugs only for ford 7.3 powerstroke.
you can buy them from rock auto for around $10 each

I just got my zd-11's for just over $9ea. I think you can even get zd-11 glow plugs on amazon for around $9.35ea with 2 day shipping.

I would test the gp relay again with a meter and test glow plugs from the valve cover harness plug.

I seriously doubt you will see any benefit from a fuel heater. if you can't start in 40deg weather, something else is going on.

I wouldn't run anything but the beru zd-11.

Test for continuity and resistance from the under valve cover plug before you go tearing the truck apart. there could be an issue in your plug pigtail as well, but 1 step at a time

I believe you want the gp's to be reading anywhere from 0.5-2 ohms to be good. continuity will assure you have a good connection to the gp's as you probably know
