When my LP failed, the sound did not change. I use Carcode, and the LP relay reported that the LP was drawing the usual amount of power. The motor in the LP ran as usual. It just stopped pumping fuel. I discovered this when I went to bleed water from the filter. Rather than the LP pushing...

New fuel lines are in and working. I treated the rust on the tank and the sending unit. I got the bed off and back in place by myself, using lots of 2X4s and the truck's jack. Tomorrow I bolt it down, reconnect the lights, and test drive. There's a lot of frame rust. I'd appreciate any...

Fun as that would be to watch, we're finally making some progress in cleaning up the harbor, and we're trying to keep junk out of it. :D This PMD would be my spare. The original is still truckin (knock wood). Maybe I'll go with a bumper or grille mount, and keep the PMD in the glove box...

I'm thinking through where to mount a spare PMD. I have my eye on the dtech kit from pmdcable.com. Bumper mount seems unwise in Boston -- we use our bumpers for contact. (Just this morning I saw big Ford SUV push on parked cars to make a parking space bigger.) Has anyone looked at mounting...

New pump is working. I get 7 PSI on dirty side of the filter at idle. It's a fairly new filter, so I'm guessing we have 5 psi at the IP. Next steps include replacing rusty return line, putting the utility body back, and testing on the road. I'll publish new pictures when I get to road test...

My sending unit works. It's rusty, but it works. I plan to treat the rust and leave it alone, for now. My immediate task is to replace the dead lift pump. The fuel line fittings are corroded, so I'm replacing them with rubber. Given the state of the sending unit, I'll cut the rubber hose...

rusty fuel tank fittings Today, I slid the utility body back so I could get to the tank. More rusty fuel lines. I'm not prepared to replace the tank today, so I guess I'll just cut the rubber, connect to that, and leave the tank fittings alone for now. I'll clean it up and hit it with rust...

I plan to fix this as soon as my new Walbro arrives. While I wait, I took a brief spin to measure the pressure with a dead LP. Given that I'm going to install a pressure gauge, it seems wise to install one that covers the full range of pressure/vacuum that can happen. I was thinking that...

I measured the vacuum the IP pulls with a dead lift pump. I plugged the combination pressure/vacuum gauge into the fuel bleeder outflow hose, so this is measuring vacuum at the dirty side of the fuel filter, attenuated by about 18 feet of hose and the bleeder valve. Next step is to repeat...

Sorry about that. I'd filled out my profile, but overlooked my sig. Fixed. I agree that the '99 torque specs probably match the '98. If I'm going to be working on this engine, I need to get the right documentation. What do folks here use/recommend, and where's a good source? Do I need...

NAPA has "Plenum" and "Intake" gaskets. Are they the same as "upper" and "lower"? Can anyone point me to a reliable source for the torques I should use in reassembly? I have a sad history of shearing off bolts... Thanks, -jpg

I've seen references to the mess people sometimes find when they remove the intake manifold on a 6.5 TD. They mention decayed vacuum lines, and other items damaged by long-term heat exposure. I have to replace my corroded fuel lines and failed LP. While I was at it, I figured I should also...

When I opened the bleed valve with a dead lift pump, the IP sucked in air which killed the engine. Here you can see the funnel I used to mostly replace that air with diesel. I opened the T valve and the fuel filter bleeder, and added diesel until it came out the fuel filter bleeder. Then I...

Here is the underside of the fuel pump relay, and the jumper I used. Below the pins on the relay you can see numbers. On my '99 C3500, #87 is always hot, even with the key off. #30 goes to the lift pump. There are many differences among model years. This is what worked for me. YMMV...

"The bunch here" is how I got this far. Thanks guys. -jpg

I wanted to learn about diesels, so I got a PennDOT '99 C3500 with the 6.5TD and 175K on it. School bus yellow. I've rebuilt motorcycles, so I have a clue, but Diesel is new to me. Though the info in this post is probably obvious to the masters, it took a lot of web reading for me to assemble...

I just spent some time looking around at prices. dieselfiltersonline has Delco TP1256 for $16.95 each plus $8.95 shipping for up to 14. More than 14 and shipping is free. Amazon has them for $20.80 each with "free" shipping. So for 1 or 2, Amazon is cheaper. More than 2 and...
