Welcome to the site!

The diesel trucks came with a vacuum pump mounted behind the alternator. It lrovides vacuum for the fast idle and power brakes. There should be a large hose coming off the alternator that goes to the brake booster. Oh, there's a T in the vacuum line and it operates a recirculation air flap for the a...

Well, it does appear to be an original diesel truck, but with some modifications. No, the filter is definitely not original. Im trying to figure out the white contraption behind the filter. Maybe a vacuum pump? And did soneone adapt a cruise control onto the truck? What's the thingy on the firewall ...

Welcome to the forum. With a few more pictures of your engine bay, we might be able to determine if this was an engine swap into a gas truck body, but I can tell you that isn't the original fuel filter base nor filter type. Someone may have removed the original one and replaced it with the one you'r...

Oh yes! A 15/16" is what I used on my oil drain plug. Not the correct size in metric. Engine oil is same size as the tranny plugs. That SAE size sorta fits but a bit too loose for those overtightened transmission plugs. Most of the filler plugs I'd seen over the years were buggered up by the wr...

10-4 on the drain plug. Be sure to pre-loosen the filler plug while its out of the truck.

I was hoping to hear if you checked to see if there had been any gear oil in the tranny. Takes motor oil. Gear oil is a no-no. The drain plug also has a magnet that'll collect worn ferous pieces. Also, take a moment to find a short socket (correct mm) and breaker bar. Break the filler plug loose. fi...

By trial and error and more errors I found that it starts right up after disconnecting the single wire temperature sensor near the thermostat housing. I believe it controls the fast idle, but fail to see why it makes a difference. I'll just accept my luck! The single wire is for the glow plugs. 2 w...

Nice work! This post might be worthy of a spot in tje How-To section. Sure beats the heck out of the ones I've seen with bolt heads along the bottom.

I hear ya. His prev job must have been at one of these modern "cant sell you a part if you dont tell me what vehicle its for" ignorants. I ran across this just asking for an FL1A filter cross reference or an old ford starter relay.

I hope it works out for ya.

Tell him you got tj6e year wrong and its for a 93. What does he care anyway what it's for.

This is very good information! Thanks Jake. Ill save tjis in my. Personal archives for quick reference in the future.

If you bypassed the fusible link, it should be replaced.

Im backing out of this thread. I've owned maybe 1 pup with air and it didnt work, so I'll leave the rest of the discussion to those who have more experience. I drove my non-ac pup for about 20yrs and survived
Good luck.
