How hot does the non-veg gas tank get?

[svswan]

I read the new info Greasel put up about Powerstrokes and it says the stock filter not only takes grease just fine, it's also heated! Has anyone ever taken a reading of thier gas tank with one of those infrared heat guns after a long drive? I wonder how hot the filter and motor will heat the fuel to. I wonder this because I will not get my conversion done for a month or two and I plan to run a veg/dino mixture untill then. I would feel safer about higher levels of veg if I knew the fuel gets heated up.

Anyone with an infra-red temp gun willing to take a reading after driving on diesel for a bit?

I haven't measured, but I have been under the truck after a 30 minute drive, and when I felt the return fuel line to the rear tank, it was definitely quite warm to the touch on the outside.

yes it is heated but notorious for going bad most have disconnected thier heating element cause it comes lose from where it is soldered(spelling [img]/ubbthreads/images/graemlins/shrug.gif[/img])and shorts out against the housing case dieing and no start situations also the filter housing has a tendecy to rot out and leak although I'm like you and hope it works good enough for a mix I'm going to try for a 40% WVO mix I think probaly 50% come summer as for my IDI the heater hoses pass right by the fuel filter so I think I'm going to try and loop the heater hose around the filter to help pre heat the mix before it gets to the injecter pump and send a hotter fuel back to the tank [img]/ubbthreads/images/graemlins/shrug.gif[/img] [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

Hot to the touch is good ;-}

That would suck to have to disconnect the fuel filter heater, it was so kind of Ford to put it there for us. I completly forgot to go under my truck and hand test my tank. I'll do that today after a dump run.

Please don't make blanket statements. There are over 2 million PSD's on the road and I will bet you $100 cash that 99% still have the filter heater connected and working. For just 1% to be disconnected would have to be 20,000 engines. I find that real hard to believe, non the less over 50%.

And I have NEVER in the 5 years I have been on this site heard of a fuel filter housing "rotting through" [img]/ubbthreads/images/graemlins/shrug.gif[/img]

i have personaly replaced two filter housings on a psd for customers so it does happen and at $400 it aint cheap

I've disconnected my fuel filter wiring from the cannister since it shorted out and left me stranded. Don't need it anyways in Hawaii since it's summer all year long. And it was on this site that helped me discover and remedy this problem.
As far as how hot does the tank get... [img]/ubbthreads/images/graemlins/shrug.gif[/img] Sorry.

I hear that the filter heater could be a problem, but maybe not as prevelent as first implied. I'll certainly keep that in mind if I have trouble. In the mean time I hope my keeps heating - I'm going to 50/50 next tank!

Remeber the fuel is also heated up when it flows into the heads on its way to the injectors.

OK so maybe I should have stated 94-97PSD's but I let it slide cause I was replying to a guy with a 96 my bad [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Maybe you should read more [img]/ubbthreads/images/graemlins/shrug.gif[/img]If someone post on the 94-97 forums about their truck dying or sputtering about 2 of the most common answers are CPS and unplug the fuel heater and yes I have had to replace the fuel bowl cause it rotted out and I already had the heater unplugged Thanks to this site cause it kept blowing a fuse I posted that and everybody knew what I was talking about and told me to unplug it and it would stop so it must be a fairly common acourance [img]/ubbthreads/images/graemlins/shrug.gif[/img]

I didn;t mean for it to sound like they all go bad I just wanted to give you a heads up that they can be problematic and expensive to replace and I did not want you to put to much faith in your fuel heater and it leave you stranded with out no warning [img]/ubbthreads/images/graemlins/shrug.gif[/img]I'm looking into some racor heated units [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

Thanks Aric [img]/ubbthreads/images/graemlins/warmsmile.gif[/img] I most certainly don't want to be stranded! What I don't get is if the heater on the fuel filter goes out how does that stand me? If I'm running veggie with only the stock filter I could see where things might not be as toasty as the engine would like, but the motor and filter were not designed for veg. Does the computer shut the motor down if the filter heater goes south (or I guess that would be north if it goes cold...)?

When the heater shorts out it blows I think its either #20 or #22 fuse out under the hood I can't remember which one it is for sure and I can;t remember what all it runs right now but I know the truck will not run with this fuse blown [img]/ubbthreads/images/graemlins/shrug.gif[/img]

[/ QUOTE ]

No it don't shut down with out the heater just if it blows the fuse cause what usually happens is the heating element the thin wire about halfway down inside the filter housing comes unsoidered and shorts out against the housing most guys fix for this is just disconnecting it and replacing the fuse and keep going [img]/ubbthreads/images/graemlins/shrug.gif[/img]

this was my point I just didn't want your whole system to be reliant on your stock heater to work with out a heads up that the heater might go out at any time and you be in a pinch to replace it or rework your system to work [img]/ubbthreads/images/graemlins/shrug.gif[/img] [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

[svswan]

thanks for the thought - When I get it converted for reals I'll have plenty of heat along the path to the motor and it shouldn't be a problem. In the mean time I'll learn where that connector is and carry a spare fuse to be ready if it fails - knock wood ;-}

Sounds like a plan stranded MY brother twice before we found out about it [img]/ubbthreads/images/graemlins/shrug.gif[/img] [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]
