Might be cheaper to replace the whole FFM, rather than just the fuel heater.
Yep this is true. I'm contacting guys I know that have replaced their FFMs with something else to see if they want to do some horse-trading or something for a reasonable price as money can be scarce these days.Might be cheaper to replace the whole FFM, rather than just the fuel heater.
I yanked my ffm from my 94. I have it sitting in unknown condition. Truck has 120, 000 miles so im guessing original stuff. Is there a way to test the heater in it? I dont need it.Yep this is true.

That being said, I'm glad I stockpiled some parts for a later time before my job was gone. I just didn't make it to this one. :HiHi:
Can you apply 12V to it and see if it gets hot? Don't do it too long without a load to absorb the heat.

According to the shop manual, to test the heater, it needs to be 46F or lower. If testing in the FFM, it needs to have fluid in it (no dry testing?) or if testing just the heater, submerge in ice water.Ill give that a shot. Since its 55 outside I suppose it should heat but ill have to bring it in the house for the first test.
Wanted to give you a big THANK YOU, because I used your thread and pictures to go off of for dropping my fuel tank and deleting my fuel sock this past weekend. Your instructions made it that much easier. If I had to do it again, I could do it in half the time now.
Also installed an inline WIX filter before the lift pump. This is temporary until I can gather up the rest of the parts for my FTB system deleting the stock FFM altogether and go 3/8" braided -AN lines all the way from tank to IP.
Heavy, the autopsy on the 39405 is underway. Enlisted the help electrical engineer friends to help with this one. Hopefully will get some interesting info in a week or two.39405 you say? I know some folks who would like to inspect that toosted PMD, myself included if you dont mind?
Curious, if your IP has the updated harness (grey connector) or not?
Anyway.. Gladly pay S&H to 67401, LMK..
