last night. going to rig a pre-filter for my new Walbro fuel pump. And replace the box filter with a spin on with a water separator.

pre-filter

main filter

filter base

and the new lift pump.

I have a new wiring harness for the pump. I got both from Leroy Diesel.

As soon as we get a cold snap (under 100 heat index) I will get to work on it...
 
The main filter is a 3 micron ?...the factory 33123 Wix on my '82 is only a 10 micron and the secondary filter (if equipped,my truck has none,may have been deleted ?) has a 6 micron rating..

Nothing wrong with overkill,but with a 3 micron rating you may not even need a pre-filter,especially with the "sock" in the fuel tank doing most of the pre-screening..

I'm going to see if that main filter has the same gasket dimensions as a 33123 does and would fit my factory base--if so I can probably get those cheaper than the 33123 Wix and it'll have more filtration..
I've put off replacing my fuel filter since I got the truck in 2003--but its only been driven maybe 8000 or so miles..
 
Looks good. How much did the Walbro pump cost? :thinking:

$145. Got it from Leroys

That's just it. I think my sock may be clogged from trash over it's 26 year life. I'd bet it is probably original to the truck. I'm also afraid I may have algae in there from sitting. I ALWAYS use Power Kleen when I fill up, so maybe 50/50...

I am going to remove the sock, run the pre-filter and pump close to the tank and use the main as a "last chance" filter. As for the rating, I got that from the diesel section here years ago while doing my "skooling". :D
 
You can get new sock filters ,they dont cost that much...
I wonder if you'll run out of fuel sooner with no sock,or suck air easier,if you ran real low on fuel,since the sock basically lies on the tank's bottom..?

Nothing wrong with your solution,as long as that wont pose an issue..

I thought sure the fuel tank I replaced a few years ago on my pickup would be full of nasty--I rarely put more than ten bucks worth in it,and the truck sat a lot during warmer weather,it got used to plow mostly,and go to the dump every month or so..

I only added maybe a quart or two of stuff like Howe's or Power-Kleen in small amounts at a time over a ten year period and to my surprise when I got the tank off and the sending unit removed,it was sparkling like new inside,except for two brown rust pits that had eaten though and made the leak..

A small amount of rusty red powder clung to the area over the pits because I stuck a speaker magnet on the underside at that spot..(it actually slowed it from a stream to a slight drip every minute or so,and allowed me a few more months time to drop the tank..

I saw no evidence of water,and whenever I drained my fuel filter I never caught any either,much to my surprise..

Maybe it was too cool up here to grow algae,I never heard much about that when I worked at a parts store that had a semi-truck parts section ,water in the fuel and rust pumped into tanks from dirty filling stations was the most often heard complaints by the truckers..they probably used up fuel too quickly to have algae grow--if anyone's tank should have had any,it should have been mine!..:eek:
 
I try to fill up when it gets down to 1/4 tank. I think I need to fab up a pre-oiler tool, it's been sitting way too long.
 
I keep my tank as full as possible (depending on my funds)--I get nervous when I have to stop on a steep grade and sit there at a stop sign or red light with less than 1/4 tank,I have had it suck air before and nearly strand me,I was lucky the electric fuel pump I added as a "pusher" to feed the lift pump helped it self bleed before the batteries wore down..

My Suburban has sat as long as a year oil more,I dont worry about pre-oiling it--by the time it shows any sign of firing up,its been spun over about 30 seconds,and oil pressure is showing 40 lbs on the gauge by then!..

If you drained the oil, and let it sit a long time,yeah,then I'd want to pre-lube it by some other means than cranking it over though..

We used to sell a aresol can with a hose and a 1/8" npt fitting to pre-lube an engine after it was rebuilt,it was like a fix-a-flat can,only full of light oil--you screwed it into the oil pressure sending unit threads--I haven't seen that around lately in parts stores,but is probably still available..
 
I was thinking about using an old vacuum pump and cutting the housing down & using a drill motor to spin the shaft, similar to a gas engine. I am aware the diesel pump uses a hex head vs a slot. Save the batteries for starting...
 
I think some 6.2's like the '87 one I have from a C30 ramp truck that had a SM465,and no A/C,had some kind of "dummy shaft"in place of a vacuum pump if none was required ,there is just a freeze plug corking the hole a vacuum pump would have gone in--I never looked under it to see whats in there--maybe that shaft could be modified to use as an oil pump primer..
 
oh yeah, lots of 6.2l goodness came in today...
