Zeisshensoldt's road trip

[gimpyrobb]

Seems he is driving a deuce from NY to FL. He called me with an RPM issue. He said initially, he could run 2400 rpm, now the truck is struggling to hit 2000rpm. I had him check for brake drag and he didn't find any hot hubs. I figure its probably the fuel filters. I tell him how to check to see if the in tank pump is running before he swaps filters. He says it isn't working. I told him how to change the fuse and what type/size to use. He is soldiering on, but I wanted to make sure I wasn't missing anything. He is going to find a fuse first, to get the pump working. If it starts working and it doesn't help his RPMs increase, wouldn't you think filters?

Anyone got any other ideas?

I would agree on the filters as a likely cause. Also could be junk starting to plug up the bottom screen on the in tank pump.

 

[hndrsonj]

I'd do filters.

 

[scoutmanadam]

+1 for filters

 

[srodocker]

I agree on filters. i had the same problem and a cpl guys around here did as well... did the filters and bam golden!

 

[doghead]

I thought he was from Maine. Isn't he going to Maine?

I have one truck that is a dog and slow(top speed) without a working in-tank pump.

If the air-pack was causing drag(due to air pressure buildup), I have "cracked" the drivers side glad hand valve, to eliminate the pressure build up in an emergency situation.

Changing filters is a great idea, if his in-tank pump is functioning. Without it, it might be a problem.

I talked to him on the phone 20 minutes ago, he was at the NJ/PA border rest stop off I-78.

I can confirm he said he's heading to Florida, not Maine.

I also said filters, he also said he had a steady leak of some sort but couldn't identify where it was coming from or what it was. I'm thinking fuel leak.

On my M35A2 recovery from Wis. to NY I had a simular problem and it looked like a drip from the IP. After a half a day of driving the fuel was squirting out of the IP! I could not get the truck to go fast.

 

[gimpyrobb]

Don, his leaks are no where near the IP. I doubt its the same issue.

 

[Katahdin]

Got a text from him. He's stopping at a hotel in Harrisburg, PA tonight and is requesting if someone can meet up with him.

Get some of the leaked fluid on a paper towel and put a match to it; see if it burns. That will tell whether it is fuel, oil or coolant.

 

[gimpyrobb]

Oil is fuel, that will just tell you if is flammable or not.

 

[shenkmen]

Gimp, PM me his contact info. I'm an hour away. The best I can do is get there at 4:30 tomorrow. I'll see if that will work.

 

[Katahdin]

Zeisshensoldt is at the Allentown, PA Hampton Inn, can someone local assist him to show him how to change the fuel filters?


edit: PM to Shenkmen sent

 

[gimpyrobb]

I dunno if I'd change the filters till the pump issue is taken care of!

 

[shenkmen]

Just spoke to him.

He mentioned that the tank has an issue taking fuel. It fills up / overflows and then the level goes down.

I'm guessing there's a bunch of crud in the tank. Thoughts?

He's headed out to the truck with a flashlight to take a peek.

 

[gunboy1656]

Is it actually overflowing or just foaming?

 

[Tow4]

Oil is fuel, that will just tell you if is flammable or not.

That's the idea. The coolant won't burn. Oil will not burn well and smoke a lot. Diesel will light right up and burn easily.

This might seem like a dumb question but does this happen with the strainer removed.
