...and doing fine!

 

Do you have the original injector pump, and if so how is it holding up?

 

Ditto, plus did it ever cleanout your tank and clog the fuel filter like some people claim it will?

 

The truck still has the original injector pump as far as I know. I bought the truck with 201,000 miles on it, and it hasn't had any problems.

I can't say what the inside of the tank looks like but drained fuel out of the filter/separator looks pretty clean.

NOW that I say this, I need to mention that yesterday I replaced the transfer pump as the old one failed. After I put the new one on and primed it, the truck ran great. Since it's been cold and I didn't run it for a couple of days, I let it run about 20 minutes.

THEN, I go to start it and nothing. Engine turns over, but it won't start. I figured the new transfer pump was faulty, si I bought one from Cummins. Put it on, no dice!

Anyone have any ideas? I don't think it's related to the B20...

 

possibly bumped the wire to the shutoff selenoid?

I have heard the cold weather is not good for bio, gells up quick.

How is power and economy on it? I would love to give it a try as I grew up farming.

 

Hi Andy,
Checking the shutoff solenoid is something else I'm checking today.
Here in NC (other than lately) supercold weather is something we don't have for extended periods like you would in Kansas, so the bio hasn't been a real problem. I still put in an additive, just to be safe.
Power and economy don't seem to suffer. The best I've recorded so far is a little over 19mpg at 70-75mph. Right now it's not getting that much because from November until February all the fuel here has additives to keep emissions down. Never mind we are using more fuel, putting more emission into the air. Go figure.
I'm happy with the bio, and can get it locally in three stations. Out there, you probably have many more stations offering it.

 

My truck did this and all I had to do was wiggle the wire to the solenoid. THe contacts on the clip had gotan dirty. When I got home I cleaned it and put some die electric grease on it.
Been working for a year now...

 

Checked and cleaned the contacts on the wires to the solenoid today. Made no difference. Doh. Going on four days of it not running is killing me!

 

Can you be sure you are getting fuel out from your transfer pump? If you can bleed out fuel when you prime it manually you still might not be getting enough volume for the inj. pump. I would check the strainer in the fuel tank, using the Bio might have finally cleaned all of the junk from your tank and blocked it. Also know you said you were using B-20 so it will have a higher viscosity especally when it is cold and could be too thick for the pump to draw. I see you are in the east, what is the temprature there? Also is this truck outside or inside a garage where it is warmer. Also check for leaks on the suction side of the pump. Jim.

 

Hi Jim,

The transfer pump is indeed getting fuel and when I cracked the line to the injection pump it was full of fuel. I never thought about the B20 clearing lots of trash in the tank - glad you mentioned it. When I put on the new t-pump Tuesday, the truck fired right up even though it had been in the low teens overnight. Today it will be nearly 70 degrees here, unusually warm for this time of year.
