the other day i went out and backed off my star wheel. Since i did that i have low boost #s it is 15 used to be 24/25 . I have returned the star wheel to were it was and same thing low boost any ideas? I am thinking of doing a radiator flush soon what are your thoughts on that as well.


thanks, Joe

 

Two things come to mind. Are you sure you put the fuel cone back the same way? Is the fuel pin stuck? Take it apart and move the throttle lever to full throttle, the pin ought to pop out. You will have to push the pin back in with a screwdriver before you put the fuel cone back in.

 

i tried to see the pin and no luck does the truck have to be running and if it is stuck how can i fix it


thanks, joe

 

Don't do it if the truck is running! You can end up with a massive fuel leak that way.

The pin should stick out of the front of the bore the fuel cone goes in. There may be a small amount of diesel/oil in the bore that's preventing you seeing it. Penetrating oil is about the only thing you can do short of tearing the pump apart.

 

thanks i will try that. Also what do you think of a radiator flush?

 

As long as you're not expecting it to give you more boost, go right ahead.

Seriously, though - if it's not running hot don't mess with it unless you are prepared to replace the radiator. Dirt and corrosion may be all that's keeping the coolant in at this point.

 

i have a leak right now it is small and i was going to do a flush and put in some radiator leak stop stuff insted of paying $200 to have it fixed.

 

Flush it and the leak will most likely get bigger. Unless you're just limping this truck along replace the radiator.

 

ok i will replace it. my pin is not coming out at all i tried the penetrating oil and no luck any other ideas.

 

With the afc cover off and the cone out, hold the throttle wide open and gently tap on the housing with a small plastic mallet...it should pop out at that point. My old pump wouldn't spit the stupid pin out with just cycling the throttle, but a few taps with the mallet and it popped right out! My slippery juice of choice here is di-electric grease...seems to stand up to heat better than most and won't run off the pin when it is hot. I put some on the cone where the pin rides and a touch on the bore and with my starwheel all the way to the top, fuel comes on smoothly and consistantly with no sticking to date

thanks g i will try that tomorrow and let you know. this is bothering me because my truck wont get out of its own way .


thanks joe

 

by the way dont get your radiator fixed new rebuil one cost me 300$canadian not worth fixinf old one

 

Ok so the malet did not work any other ideas or do i have to rip into the pump and how hard will that be is their any special tools or just the basics

thanks, joe

 

i got it i had to tear down the pump that was a first thanks to every one that helped me.

thanks, joe

 

glad you got 'er done too bad you had to tear into the pump to do it though
