fill them both, take out a few glows on each side, turn the engine until mist comes out from the glow plug holes(you might need to let air out of filters with bleeder screw), reinstall and start.... if you are running mechanical fuel pump, this method works well, if you have an electric pump, you can just let air from the bleeder screw on filter, and crank... be careful not to crank to long, crank, rest, crank, rest.. no longer than 10-15 seconds of cranking, then let the starter cool for 20-30 seconds...

 

Yes, I have a mechanical pump but I can not take out any glow plugs

I have been using plug-in cord for months because GPs are stuck and I'm too afraid of breakage to let anyone remove them. Still looking for someone competent. But that's another story

 

I think your 83 has spin on filters. If you have a vacuum pump at the rear you need to pull it (15mm) to get the secondary filter out which is mounted on the intake manifold. I use a siphon to fill my filters from the tank then install. You have to carry them like the egg in the spoon thing. Some guys fill the new filters with the fuel from the old ones but i dont dig that. Turbo says pull glows but i have had luck with filling my filters and just running the air out. Also if your truck is set up like my 82 and you are running a mechanical pump dont open the bleeder on the primary (larger) filter because it will just suck air in. For some reason the fuel feed runs from the tank straight to the primary filter then down to the mechanical pump on the block then back up to the secondary filter. Stupid:think: right. Anyways if you have an electric lift pump youll be on easy street, good luck. BTW I was on vacation last week on the gulf side. Could have helped you out if you posted a week earlier:HiHi:

 

Yes..mechanical pump. I put diesel in a Gatorade bottle I plan to use

I don't know about a vacuum pump but I think the secondary is behind the air filter. I may change the primary today and do the other another day

Hope you enjoyed your vacation. Good thing I didn't know you were here. My burb would have worked you to exhaustion :HiHi:

 

Ya secondary is on the back side of the intake behind the air cleaner. Good call on tackle it another day. Next time maybe you'll catch me...

 

One big tip is to un plug the green wire on the IP, it's the cold advance solenoid and it free's up the return system to speed the air getting out of the filter/fuel system, get it running then simply plug the wire back in.

 

Can you be a little more specific on where the green wire is? I only know green wires on the Glow Plugs

 

On the injection pump right in front of the air cleaner. There is one pink and two greens.

 

here is a small picture that shows where it is. It is labeled with a faint green color that is hard to read, but points it out pretty well.

You don't need to remove the glow plugs, it just makes it easier for the engine to turn over and doesnt drain the batteries as easily. If you pre-fill the filters you will probably be fine just cranking it over. It might take a few tries to get it started and worst case scenario is you might need to put a battery charger on for a bit and then try again.

The last time I changed my fuel filter I filled the filter, installed it and it only took 2 maybe 3 tries to get it started. And I didnt pull any glow plugs either.

Don't worry about it too much, it will go smoothly and then you will be a seasoned pro for next time

 

ok the photo I tried to post wasnt working, so here is another. in this pic the front of the engine is towards the right. its labeled c/advance and you can see the dirty green wires

 

UPDATE: Today, my truck was acting fuel starved so I had to do something. I'm such a procrastinator and chicken

The primary came off easily. The fuel inside looked clean but there was rust on the filter deep inside. Filled the new one, disconnected that green wire and it started right away. After a minute or two of acting rough, it smoothed out and seems ok now.

Haven't changed the other yet. I think I need a helper for that one, but that's for another day

 

Great to hear you did the one filter, don't leave the other one too long.

 

That was some great advice that I didn't take. :duh:

Just about 4 months after changing the primary, my engine acted up again and I had to get towed home. Yay for AAA

This time we changed both filters. That second one is a doozy. It unscrewed ok, but we had to remove the holding bolts, in order to get it out. Really? That can't be the way it was designed

It took 5 tries but it finally fired and I'm back in business. I was afraid it might be the fuel pump. So happy it wasn't

 

Before you know it, you are gonna be the local 6.2 mechanic

 

:HiHi: Her and her helpers are doing better than some of the floozies that have come and gone:thumb:

 

Oh...good thing ya got sorted out

 

I've always changed the filter when the truck is up to temp. Seems to work well for me.

Mind you....i've only changed it twice, lol!

 

Her car barely has 40K kilometres on it.

Regardless....i've hijacked her thread enough.
