Truck Running Like Crap Re-visited

***Tom05*** · 01-26-2007, 11:06 AM

Hey everybody, my daughters' truck won't start. It seems to be a problem only when it gets cold out. I tried pumping the primer button and it is squirting fuel out with each stroke. Do you suppose that the leak would be worse when cold? I know it needs to be fixed, and I seem to remember that there is an "O" ring that can be replaced rather than putting a new LP on it. Anybody remember where the info is?

Tom, I had something similar happen before Christmas...it was -20 and the truck was pouring fuel out of the bottom of the filter (around the drain tube). I couldnt get it to stop and the truck wouldnt start. Ended up pulling off the filter housing and cleaning it up. I also removed the drain tube (there are two torx screws [T25 I believe]), and two o-rings inside. They are not viton etc. and are green in color. I didnt have any orings that that matched in size so I just cleaned them up, regreased them with some think grease (teh AMSOIL guys would be happy with my grease choice

) and reinstalled everything. I changed the filter, bolted the housing back on, primied it and she fired right up.

Its an easy job (other than getting the filter housing off/on)....Its a good time for your lil girl to learn about her new truck....

This leak is definitely coming from the primer. I went and got a new pump, even though the 'old' pump is supposed to be less than a month old..:fist: Believe it or not, where I got the pump, they don't even have a gasket listed for the pump! I have some gasket material so that is not a big deal. Just trying to line everything up is a big deal though........... What a PITA. I have not been able to get the bolts started, so I am going to go find some studs to get things lined up. The bracket for the fuel heater is what is holding me back from getting tit together. Good thing my daughter is working otherwise she would be hearing some not-so-nice words...........

Loosing the bolts and using studs to reinstall lift pump. Much faster and less swearing.

If anyone want's the stud size, It's 8mm x 30mm x 1.25 pitch.

The O-ring is a standard size, I just pull one out of my assortment tray every ten or so years, so do not even remember which it is. I also lube the button before I install the o-ring, and keep it lubed every time I grease the rig, and I toss the rubber button cover as being useless.

To make the transfer pump easier to install, roll the engine over while pushing the push rod back in. Once the push rod is back on the low side of the camshaft lobe the pump will just about jump on. With the push rod on the high side, it is a beast to reinstall.

Well, I got it together. It actually runs!!

It seems to be much better now. Time will tell if it acts up when it gets cold out. I really think that the leak was the source of air that was giving me fits................

Sorry Tom....

I misread your original post - didnt see your leak was from the primer itself...

***Tom05*** · 01-28-2007, 02:06 PM

Well, it still ain't fixed............ I am gonna post about it in the 12V forum now since it isn't an urgent problem now.
