    Intermittent cruise control

    I doubt it's related to cleaning. Have you ever heard about the cruise control recall? There's a cruise control cutout switch on the brake master cylinder. Some trucks have burnt down because of it. You should check with a dealership to see if the recall has been done on yours. Sent from my...

    ??? about throw out bearings

    Maybe not the factory one, but I seem to recall people swapping to a greasable one. Sent from my SM-N960U using Tapatalk

    My next F700?

    Ah, I couldn't find anything specific. On our 98 f800, the computer systems don't really recognize that combo. Sent from my SM-N960U using Tapatalk

    Far as 12 to 24v, did they carry the same switch over year as the pickups? Sent from my SM-N960U using Tapatalk

    My next F700?

    I see. You may look into the international lineup. Very similar trucks, similar engine options as well, but more run the dt's. We have a little of everything at work. International, western star, kenworth, freightliner, mack, sterling, and ford. Sent from my SM-N960U using Tapatalk

    GDP 6 Position Chip - 7.3L Ford 02-03 Automatic

    It will definitely make a difference over stock. I left mine in the highest setting that php offered. Sent from my SM-N960U using Tapatalk

    My next F700?

    I wouldn't jump on a 24v over a 12v just because. They aren't making that much more power. Also, I believe the 24v will have the ve pump instead of the p-pump.(aka being electrical instead of mechanical) It looks like 92+ is when the 5.9 and 8.3 became options. Also, any reason you are only...

    GDP 6 Position Chip - 7.3L Ford 02-03 Automatic

    Through that company, yes. I don't have any experience with GDP. Thoroughbred is just a middle man. Standup company, but if the "manufacturer" (ie: GDP) no longer supports, thoroughbred can't do anything about it. They don't typically fail. I would say it will get you by awhile. I also know...

    air intrusion

    If you want a simple fix, put in a check valve on the supply side. "Correct" fix would be replace your return cap orings, full line "olives," and the hose between the lift pump and frame rail. Sent from my SM-N960U using Tapatalk

    My next F700?

    What I'm finding is the 3208 isn't great in a truck setting. They like to eat bearings when ran at higher rpms. You can hop up a 5.9, but it's still small for the application, imo. We have a 98 F800 setup as a grabber truck. It has a 5.9 12v and allison. Empty isn't too bad, but any kind of...

    GDP 6 Position Chip - 7.3L Ford 02-03 Automatic

    For the price, I would go ahead and buy it. It appears they are so cheap because GDP Tuning has discontinued them. Sent from my SM-N960U using Tapatalk

    I didn't even notice the price, that is cheap. Only thing is, no telling how much longer places will burn tunes onto them. Sent from my SM-N960U using Tapatalk

    Get the hydra. Those old style rotary switch tuners are outdated. The hydra you can download the tunes yourself, so in the future if you get a custom tune, they will email it to you and you put it on. The rotary switch style, you have to mail it in. 1023, jellibuilt(sp?), cncfab, are names I...

    My next F700?

    You realize Detroit's are still being made? I'm not talking about one from the 60's. What year range are you looking at? That'll help us give you more specific recommendations. The cat c7 isn't bad, can be tuned for more power. Trans is going to play a role as well. You want a allison or a...

    It's a truck, mileage isn't really a factor. Lol Skip the 5.9. Get a larger Detroit or a 8.3 cummins. Sent from my SM-N960U using Tapatalk

    It's on the side of the fuel filter bowl. It runs off the same fuse as the pcm. #22 in the under hood fuse box, iirc. Sent from my SM-N960U using Tapatalk

    O’Reillys don’t buy on line

    We have one "mom and pop" style, a locally owned bumper to bumper, and oh-really. The mom and pop is my main go to. Then bumper, as they will get me a decent deal, plus pretty quick if the have to order. Couple weeks ago the fella at oh-really try to short me out of $20. Sent from my SM-N960U...

    Super clean will strip it off. May take a few go's, but better than a stronger cleaner, imo. Sent from my SM-N960U using Tapatalk

    Technically that's all fords, well up into the 2000's. Maybe 2008 they started using relays. But he said he replaced the switch and plug. Sent from my SM-N960U using Tapatalk
