Location: Lavallette, NJ 08735 | 2 Bolts, 2 Fuel connections; simple, right? I'm no mechanic, so please bear with me. There is a rod that seems to be a permanent fixture on cam (?) that I can see with pump removed. This is in the way of simply placing the pump in place, and tightening down. When I tried to pull pump in evenly with bolts, I cracked housing. Read some on the net, and says there is a rod that falls off the cam, and can be held on with grease while pump is installed, and that access to it is thru allen plug beneath pump. I removed plug, and do not see or feel any loose piece. Question 1: Is it possible that rod I see as permanent fixture on cam is what they are talking about, and that it is fixed (because is industrial engine? other reason?)? or is piece an extension rod that gets stuck on to that "nub" with grease? If so, I will try to retrieve piece with magnet, or something. Also, Question 2: It seems that with or without that piece, cam position needs to change to allow pump into position, unobstructed. How would I do this? Tried cranking engine already to change position, but nothing. Any related info, particularly link to comprehensive instructions/video (preferably specific to the industrial engine) for layman would be greatly appreciated! Happy Thanksgiving! Robert |

Location: Cottage Grove, OR | I am not a mechanic and cannot answer the questions you have asked except to say that the fuel pump is the same on all 440's. It is the heads that are different and create the 440-3 or 4440-I designation. When I had a fuel pump issue, I just converted to an electric pump. Problem solved. |

Location: Scottsdale, Aridzona | Hold on Robert. I'll post pictures of what is going on in the morning (Frid Nov 23, 2012). Soon as you see then, you'll know what happened, and how to install your second new mechanical fuel pump without breaking anything. What city are you located ? Lou #120. |

Location: Lavallette, NJ 08735 | Thank You! Things have been super hectic, and this is the first chance I've had to even get back here to check replies. I will look at them soon, and let you know how I make out when I get to it. Hate to say, I moved to Lavallette, NJ 2 months before Sandy hit (OUCH!); currently displaced, but doing OK. Coach #0075 fared the storm fine in northern nj. |

Location: Lavallette, NJ 08735 | Got a chance to see the photos. Excellent tutorial! I'm going to give it a shot in a while, though my defeatist mind still wants to believe that for some reason, my 440 is different than all the rest! Everything I see and read in the tutorial looks correct, coincides with everything I've read (nice to be able to see it as well!). I have a better understanding going into it. But it seemked to me that my pushrod did not budge, even with a tire iron on it! Maybe I was putting too much emphasis on trying to push it up and out of the way, as nopposed to into the block. I'm not highly confident, but will give it another go, and let you know! Thanks so much for the help; exactly what I was looking for. A rare occurence in today's technologically driven world! Usually, I just research stuff, get frustrated, store it for no less than 6 years, and ultimately sell at a huge loss, just to feel that in some twisted way, I won!?! |

Location: Lavallette, NJ 08735 | Also, should i be using any gasket sealant? Recommendations? The new pump that I broke came with 2 gaskets. Is there a reason other than an extra, or perhaps a mistake at the factory? |

Location: Lavallette, NJ 08735 | Ok, gonna go for it. My pushrod seems to go in all the way, is loose when rotating, but does not seem to wanna come out. Also, the wheel bearing grease refuses to hold rod in. As I have already removed plug, will attempt to physically push rod in from hole, while aligning pump; should do the trick. Since I haven't heard back about the sealant, will just go ahead and use permatex #51 pipe dope, as i have it, it seems to be the same as any gasket sealant ive ever used, and says it's good for fuels. As a note, repacement pump from same company, with same number, purchased 1 week apart were different, and I had to drill out the mont holes a tiny bit so bolts would go through. I'll update at a later time. Again, thanks! Robert |

Location: Lavallette, NJ 08735 | Ok, fiasco has concluded, and pump is working and not leaking! .....but.... original problem that initially got me to look at fuel pump persists. Without going crazy, suggestions as to why it starts up, runs strong for a minute or two, then just cuts off; can be restarted, but difficult, and needing gas pedal intervention. Before you answer, know that i messed with the carbeurator settings, so if it could have to do with that, just say so, and I'll persue that before anything else. (carb is not original, replaced with edelbrock something or other).
As a sidenote: I wonder, as a layman, why no one (not only on this forum, but other mopar/auto forums as well) suggested that I simply angle pump into place while pushing rod back towards block. Ultimately, that is what i did, and if I'd had that suggestion early on, could have saved myself much blood, sweat, and tears (literally); not to mention the first replacement pump ($33.), a near black eye or worse, and a slew of inanimate objects that somehow fell victim to my wrath (simply by being on the wrong place at the wrong time. Could it be that my 440 IS unique?! |

QUOTE] Many years ago, I have done what you describe. It will work IF the rod has stayed/will stay up enough to hook the lever under the rod. I did not suggest it as it will not work if the rod is in the down position and the instructions with the pictures gave such a complete set of instructions I did not feel additional instructions would add anything. Glad the pump is now working and you can move on to other things. My first thought about the stopping is the possibility of fuel filter being plugged. Have you changed out the filter? If it is plugged it would restrict fuel input rate and starve the engine. Trace the fuel line from where it comes out of the firewall all of the way to the carb and look for fuel filters - there may be more than one. I would also verify the volume of fuel being pumped by the fuel pump by removing the output line from the pump, attaching a length of fuel hose long enough to reach to a bucket behind the coach and on the ground. Then, with coil wire removed, crank the engine over and observe the volume of fuel coming out of the line. It should be a strong squirt. If not, there is a restriction somewhere from the tank pickup to the pump. If the lines are clear and the pump is working, then it is time to also ensure that spark continues to be present after the engine initially fires up. If spark continues, then it is back to the carb. Compression, fuel and spark are what are needed. Compression will not have changed. That leaves fuel and spark. They need to be there in the correct quantity/quality and correct timing. You are getting close. You will succeed! It is worth it when you ultimately get on the road. |

Location: Lavallette, NJ 08735 | Hi Stephen, hope i didnt come off as looking to blame anyone for not giving me that tidbit, more wanted to put it out there for others in same situation. My pushrod did not stay up at all, it was hanging when I angled pump in; but perhaps not hanging as much as typical, cause as I mentioned, rod would not come out either (brief attempt, saw no reason to go crazy trying). I could actually feel and hear rod being pushed back up with arm on pump. I will follow your course of action, and let you know when I do. Can't spend anymore time on it today, and don't know when the stars will align again for my next session. Thank you both so much for being there to bear with me! |

Location: Lavallette, NJ 08735 | Stephen, would it make sense for the engine to run so strong at first if the fuel filter is clogged? I would think it would starve for gas the whole time. |

Location: Cottage Grove, OR | The question is how long it runs "strong". If momentary, it could be just burning the fuel that was pumped up to the carb while cranking prior to it starting. If longer than that, then, in my mind, it may be an ignition issue and not a fuel issue. That is why I raised the question of spark continuing after the engine starts. |
