    Which replacement injection pump?

    I recently installed injectors and RD-80 injection pump from R&D IDI and could not be more pleased so far. Only a few hundred miles on the new parts but plenty of power and I've only been able to hit 900F-950F EGT on a long hill climb without an intercooler. You should call R&D to see when...

    New 3g alternator--High voltage and then low voltage, bad regulator?

    How is the 1g alt grounded? The 1g setup works very well at the moment and the E4OD doesn't complain so I think the wiring is in decent shape. New battery cables and grounds are on the list.

    New 3g alternator--High voltage and then low voltage, bad regulator?

    The alternator should ground through the brackets. I've done the 3g conversion on another truck and did not need a separate ground wire. I'll have to double check but I'm not sure this alt even has a post for a ground wire. Edit: Could you just run a ground wire from one of the mounting ears?

    New 3g alternator--High voltage and then low voltage, bad regulator?

    Wiring is solid. No open circuits. There's not much to check with these 3g alts. I double checked the 3g connector and it's good. Mega fuse is good. Alt passes basic diode test. I doubt it's an issue with the wiring.

    New 3g alternator--High voltage and then low voltage, bad regulator?

    Installed the new alternator and double checked the new wiring before starting the engine. First start the voltage slowly climbed up to about 17.5 volts so I turned off the engine and rechecked my electrical connections--everything tight and looking good. Start the engine again and get the...

    Facet pump problem?

    I had some performance issues with the facet pump but was able to increase the fuel pressure about 1-2 psi simply by blowing out the fuel lines with low-psi compressed air. I think I used about 15psi, disconnected the inlet line at the Facet pump and pushed air back through both tanks--remember...

    Coolant filter kit

    There are "as needed" coolant filters charged with SCA. I think one company is Penray and supposedly the filter only releases SCA content when the levels are low. Personally I have embraced the notion of a more frequent coolant flush and re-fill. It's surprising how dirty coolant gets and I...

    Coolant filter kit

    If the pink coolant you're using is Fleet Charge it will be a while before you need to use a charged filter to add SCA content. I can't recall exactly how long it was but after a few years of use I checked the SCA levels in Fleet Charge and they were still good. I read on a website for...

    3g alternator conversion--pulley problem.

    I used the orange Loc-Tite since I've never had it fail on me but it's still way easier to remove than the red stuff. It would've been nice to be ab;e to use the lock washer but I guess this is one of those "Better Living Through Chemicals" moments.

    3g alternator conversion--pulley problem.

    Found the smaller v-belt pulley and thought I'd post it, https://store.alternatorparts.com/partno242105.aspx 73mm OD instead of 85mm 10mm outer groove/13mm inner groove 17mm bore

    3g alternator conversion--pulley problem.

    Well that's exactly what mine looks like after assembly. I guess it's Loc-Tite to make it all-right. Or find another pulley. I've noticed the chinese 3g alternators for the E-Series 7.3 IDI come with a different dual belt pulley than the F-Series--diameter is smaller and perhaps there is more...

    3g alternator conversion--pulley problem.

    Finally getting around to the 3g upgrade but have an issue or potential issue with swapping the pulley over. I have a new Bosch AL 7508N alternator which was the only non-chinese new alternator I could find that was listed as fitting a 90-94 Taurus/Lincoln/Mercury. I do need to buy a or dig...

    Holley Red are garbage, what else quickly?

    Too bad about the Holley Reds. Were they all purchased from the same source or multiple sources? I'm not trying to revive a debate but for all its faults the Facet pump I put in an old truck was at about 70k when I sold it--if only the pressure and GPH were better.

    Best Valley Pan Gasket?

    CDD just buys and resells the Fel-Pro intake gasket and they are still cheaper than most places. They can be reused though. I found an older post from the late Towcat where he mentioned using 3 or 4 coats of Hylomar on the sealing surfaces that mate with the heads and intake manifold--front...

    Ford gooseneck manual side mirrors.

    Looking for two decent condition manual gooseneck side mirrors--the 7.5"x10.5" ones. I don't need the brackets but just need the mirror heads and arms.

    Battery jumper packs?

    The peak amp ratings for ALL those jump-packs seem to be essentially false. They may technically be able to hit very high amperage for a split second but it's not sustained output. For very short distances and duration a smaller wire can carry more current than its ampacity rating indicates...

    Starting and Trans issues after removing ambulance box

    You have an E4OD and you 100% need a functioning tachometer. The E4OD also needs incandescent brake lights or if you went LED then you need to wire in a resistor to one or both brake lights. The shop may have known how to remove the ambo box but they did you no favors in regards to the...

    Donaldson DBL7405 oil filter on a 7.3idi

    17qts of synthetic sounds a little expensive but nice to know your sample came back okay after 8k. I only drive about 9k-10k per year so the notion of just an annual oil change would be convenient.

    Can I install a kill switch on my truck?

    Maybe just disconnect the factory connector at the IP and wire in a new circuit tied to a switch tucked under the dash? By creating a separate circuit it would be easy to go back to the original factory setup should there be a need to.

    CDD injection line issues

    If you do get the whole set of lines you should be aware that more than a couple people have had difficulty timing the injection pump due to erratic RPM readings becasue the aftermarket lines are not quite the same as OEM . I replaced the #1 line and I'll get a good RPM value at idle but as I...

    I'm curious which oil you were running.

    Donaldson DBL7405 oil filter on a 7.3idi

    I ran one for a while on a 1992 4x4 F250 and I had to do a little grinding to nake it fit. The DBL7405 used to be only $20 at FleetFilter but now $40 to $45 is the cheapest I've seen. I went back to running a smaller filter from Donaldson. Edit: P550371 is the Donaldosn filter I've been...

    Anybody try converting their RD-80 to an RD-90?

    Composite head gasket? I used Fel-Pro Permatorque blue gaskets.

    Anybody try converting their RD-80 to an RD-90?

    I've been running the RD-80 for a few weeks and like it a lot, but of course there is the temptation to convert it to an RD-90 using the included instructions. Anybody try this? Results? I definitely have some ceiling left in terms of EGTs but I do take to heart Justin's warning about...

    Doing oil cooler. Is this trick legit?

    Re-torquing the bolts ought to be relatively easy. My only concern would be breaking one but if you're just going to original factory spec then it shouldn't be a problem. On my 7.3 I went to 105lbs instead of the book spec of 100lbs. The worst bolts were the few at the rear of the heads but I...
