    Exhaust tubing technical data

    I'm working R@D on a furnace and the exhaust gasses are really hot. 700°F+ so I'm concerned about a requirement that no component emit in the visible spectrum. I could go with Stainless but that stuff is expensive and I'm thinking if I just use diesel exhaust tubing I'll be well within the...

    So where do you get a descent injection pump at ?

    I had one on the truck when I got it, it died pretty quickly, say within a few hundred miles. Got one off ebay for about $400 and it lasted about a split second longer than the first one. Fixed that one by repairing one of the solenoids, lasted about another hundred miles and died again, this...

    Truck died again

    Sad to say I'm getting used to it. This time I was on the highway and the moment I switched tanks it died. I flipped it back to the other tank but to no avail. Both tanks were full, the forward one of bio-diesel the other of clean filtered motor oil. Thing shut off like a switch. I got it off to...

    Just ordered new suspension all the way around

    So I'm going to be replacing and upgrading my suspension to accommodate this huge fuel tank I've installed. It weighs about 400~1900 lbs depending on how much fuel I've got on board. and it sits directly in the back behind the cab where everyone else puts bed tanks. So I thought it best to...

    Runs like a bat out of Hell, but you damn near have to kick start it.

    So that truck I built last year, runs, more like screams down the highway. Needs a new front end, which I'm about half way to completing but that thing gets up and goes. the issue is starting it. The glow plugs click asynchronously and it sounds like its only firing on one cylinder for ten...

    Those parts I got robbed on

    So I've been driving that old truck of mine I rebuild for a short while now, maybe two months. Here's what shakes out. the rebuilt steering gear box probably wasn't rebuilt at all, it wasn't even remotely adjusted when I got it and it seems to not want to hold an adjustment. I'll try again...

    best RPM range for this new W&S vane pump

    Just picked up one of these vane pumps off Ebay for $50 and I'm wondering what its best RPM range might be. I've got two 1/3 hp motors I want to hook up to it and so I get a choice of gear ratios. I'm inclined to think about 2:1 would work fine. The motors run at 1750 so I'm thinking the pump...

    started second time just fine.

    well after months and months of being in pieces spread out all over the shop I finally got the old POS running today. Second times a charm, seems you kinda have to actually connect the glow plugs to the electricity if you want them to help you out any. Did lot of clicking when I turned the key...

    Headers = now how do I get the dam Dipstick in.

    I've got a 90 F250 4x4 XLT lariat 7.3 diesel and I just put some headers on it. Was a whopping pain in the ass. Now I'm just going through and cleaning up all the little stuff and I notice there's not a snow balls chance in hell that Dipstick is going back into the same location. Hudini himself...

    Can I ground both a 12V and a 24V alternator to the same ground

    Might be a completely stupid question but I've got a 24 volt pair of motors on something I need to run while the trucks running on a 12 volt setup so if I add a 24 volt alternator can I ground it to the same frame? and can I run the motors directly off the alternator? no batteries, no...

    well this will divide the men from the boys

    Headers don't fit, Ford and two long time veteran diesel mechanics all said that the oil cooler its hitting is standard equipment on the 7.3. Stan's says there's no way there header doesn't fit, never had one not fit before. Ford says there's no way the oil cooler isn't factory. Two diesel...

    universal injectors instead of BB ???

    OK so I just received a set of Delphi injectors for my 91 7.3 from "The Diesel Store" and they didn't specify the BB designation on the package anywhere, so I called them. They said the difference in specs was so minor that they now just make a universal injector. Should I return them and go...

    Mama woulda been proud

    So I found an old dead Ford hiding in the backyard of a friends place. I was working on his house but by the end of the day we were working on some brews. So I asked about the ole dead truck and I seamed to hit a sore spot. "Wont run" was the rather gruff response. Naturally I piped in with "its...
