  1. SavageTusk, whats your drivetrain? Stock or modified? You dont have your sig filled out.
  2. Point well taken about the rarity of the code. But knowing that Asphaltenes starts before 160*F is reason enough to wonder if the crud people have regularly seen in their tank is something worth pondering. Especially since ULSD is proven far more prone to this problem too. But that said, I understand that fuel conditioners fight against Asphaltene too so maybe thats all anyone needs... As for the solder... It would sure be nice if there was something available from Bosch regarding this issue and how it was dealt with.
  3. You should check and see if the blanket is keeping the VP cooler. Take some temperature readings while the engine is running and then about an hour or so after you shut the engine off. If the blanket is working then the VP will not be as hot as the neighboring engine and bay temperature. You certainly dont want to cause an opposite effect.
  4. I've thought about trying that too but I was more concerned about heat being held in. You have any pictures?
  5. The only viable attempt I've seen someone do to keep the VP cooled down a bit is having cool air blowing over the entire VP. Aside from its own heat generation... The VP hangs out in the open and is subject to heat transferred through the mounting base and whatever radiant heat from the motor. So speculation would suggest any air blowing over it should help. That said, a fuel cooler would seem like the most logical option. Funny too how these topics cycle too.....
  6. Did you have the stereo controls on the steering wheel too? I've heard there's adapters for those as well. Gotta be honest that I doubt the function of all these adapters and connectors. Finding out that something didnt work right would make me unhappy.....
  7. Correct, except that the VP return is only part of what volume makes its way to the fuel tank. The rest is excess fuel at the injectors. And thats actually the HOTTEST fuel as its flowing out the back of a 200*+ cylinder head.
  8. Any aftermarket fuel pump will push more than enough fuel since the whole premise behind fuel lubricating and cooling the VP is having more fuel pass through it than the engine needs. The limiting factors will always be what fuel volume can pass through the VP at any given time. Even the air separation fuel pump systems which have their own return still offer no additional benefit to fuel volume through the cooler since their return fuel is dumped directly into the fuel tank inlet. A thermo bypass, built in thermostatically controlled, heat exchanger would probable by ideal in one of these situations.
  9. I've tossed the idea around about replacing the factory deck with a single din unit. But I have the Infinity stereo and I just can muster up the excitement about digging into another wiring project. Plus the factory system sounds pretty good since I added a small sub. My biggest grip is no aux port and no bluetooth.
  10. What invasive buggers we see around here are cyclical. This year was seemingly the year of the rat. Maybe next year it'll be frogs.....or crickets again. Not sure why it cant be something edible like chickens...
  11. Rats have been the vermin of choice this year... Seems they're everywhere.
  12. Nice setup. I got into the habit of raising the hood too... Not sure it does anything other than give me peice of mind knowing that the PSG isnt being heat soaked as much.
  13. Thank you greed... I didnt know such a think existed. I may have to get me some just to keep crud out of the cowl.
  14. The things we learn over the years. Some of it useful.....most of it worthless. Either way, its makes for good small talk.
  15. This..... Diesel fuel asphaltene is no joke. Many people mistake "algae" in their fuel tank but that black crud is commonly ashpaltene from hot fuel over 140*. Its even been discovered that lower sulfur in diesel can cause instability issues too, and combined with high heat running fuel system conditions, ashpaltene particles can form. The stuff will also plug up a fuel filter too. I think there's a good reason the VP has a fuel temperature sensor which triggers at 160*. I remember having this discussion a few times on the forums years ago too but it was eventually a general consensus that this must not be an issue for these trucks since non came with a fuel cooler. Still not sure about that but nonetheless, its best to keep the fuel tank no lower than 1/2 tank in the hot weather due to the constant re-circulation of the fuel. And to aggravate the issue, the fuel module pulls inlet fuel right next to the return outlet which means unless you have a draw straw or sump your fuel in the lines could have been running round and round getting hotter and hotter. You can only imagine how hot a small amount of fuel in the tank will eventually reach. In saying all that, there's plenty of diesel applications which run fuel coolers. Even Mercedes has a diesel (not sure which one) which runs a fuel cooler integrated into the AC low pressure line. Pretty slick way to address a hot weather fuel condition. Lots of other people run fuel coolers on their diesel trucks but given how susceptible these particular trucks are to fuel leaks and starting issues, some people looked at it in that adding a cooler would only add more places to leak. I eventually gave up on the idea and to this day I will not run any lower than 1/2 tank in the summer and 1/4 in the winter.
  16. Yes, FASS and AD work the same and wire up the same using that relay. And yes, the ECM rapidly cycles voltage to reduce fuel pressure but for some reason this can still result in too much initial fuel pressure for some VP's. Tighter tolerances, heat, voltages, resistance, combination of all?.....not sure, but its more a problem for anyone using a fuel pump like the FASS or AD or Raptor. Either way, its been found that by adding another relay to cut all power to the fuel pump during engine cranking removes all head pressure to the VP. The result is immediate starting of the engine. As long as the fuel line prime is retained then this seems to be the best method too.
  17. Sounds like the way he has the FASS wired is using the ECM as the ON/OFF source and all amperage going through a relay, which is normal for those applications. But its not uncommon for the FASS to over pressurize the VP during engine cranking and hydro-lock the fuel solenoid and timing ring solenoid. Most of the time the additional cranking will allow the higher fuel pressure to bleed off and the engine will eventually start, but not always. Remember, the OEM lift pump was regulated at 15 psi and was barely capable of achieving that. During cranking if everything was in picture perfect theoretical condition then the Carter lift pump would produce 7 psi during engine cranking. As rare as it was, there's even a TSB for the Carter creating the same hard hot start problem. So you can only imagine how much more able the FASS is at delivering fuel during engine cranking...which ends up with situations like this.
  18. Sounds like you're experiencing the hard hot start problem which is common for most people who have a reman VP and an aggressive aftermarket fuel pump like the FASS. The FASS is tied into the wiring using its own loom and relay correct? Thats how FASS sells their fuel pumps so I'm assuming yes, thats how its wired up. If so, then you have a single fuse somewhere on that wire loom which runs to the FASS. Most likely a single blade fuse holder. If yes then the next time the engine cranks and cranks but wont start, open the hood and pull that fuse and try starting again. If it starts more normal then we've found your problem. Just be sure you dont let the engine run for more than a few seconds with the fuse out. Either shut it down or immediately replace the fuse. Let us know if that works...
  19. So...something stops working means that nothing happens like a dead battery. Or nothing happens like it cranks and cranks but no start? I get that somethings getting hot but without understanding what is exactly happening...
  20. I cut wood every year to heat my house. We head out every time thinking, we'll get the smaller trees because they're easier to handle and cut. Then for whatever reason the trailer is full of round 30" or larger... Its like the trees grow in size as soon as you cut them down.
  21. How did it leave you stranded? What happened? Whats it doing, or not doing?
  22. I thought you guys all met up in Idaho...
  23. So the FASS is controlled by the ECM through a secondary wire loom? At this point I'm kinda confused and not really sure what the problem is... Can you explain again what exactly is going on?
  24. I know I can get kinda sweaty about some of this stuff, so.....let me just take a second to say that I think highly of most every members opinions. Lots of good hearted intelligent people here, and to have such discussions in a civil manner is rare. Thank you.
