I like those fuel pick-ups. If my tank ever has to come out, it would be nice to add those. Where is a good place to get them?
thanks

I got them here:

Lots of people use them with good success on pirate4x4. When they get exposed to the air, they close, so as long as you set them up so one is in the fuel somewhere, then you are good.

Bah.. too hot to work. Once it got marginally cooler, the mosquitos came out and bit me up.

Trying to get the steering back together. It seems like its too short. I swapped out the steering column, since the old one had the shifter on the tree. Grrr. SO I will melt out the plastic and extend the shaft tomorrow.

Got the pressure hose, seems like it will fit the chevy box decently. Lower radiator hose is here, fuel hoses here, vent lines, coolant, oil, and PS fluid, oil filter, etc..

Hopefully have the engine all buttoned up this weekend. Then I need to finish the shifter, get the t case bolted in all the way, and toss the y-pipe back on and see if it will fire. Probably 2 weeks out from that..

Weekend updates:

Melted the plastic and extended the steering shaft 1.25" it fits fine now and doesn't seem sloppy where I extended it. There was enough plastic to cool and setup to keep it pretty good.

I got a stock O-ring CJ power steering pressure line to work. Had to do some rebending of the pump side but it fits well and the fittings are all the same.

For the return side, I have a cooler that was stock on the silverado that my motor came from. I'm going to use that, I just need to figure out where I want to mount it.

I got the fuel pickup done with the correct SAE J30R10 (must be R10, not R9) submersible line. Ack, $2 per INCH.






Fun trying to make the whole thing fit through a 4" hole in the top of the tank. But its all in there. The capped AN line on the left was the original output from the tank. The new output is the olive green line running out of the cap, I still need to make a new -6AN hose to connect to the fuel filter. The pic is blurry so you can't see, but the fuel line is soldered into the top plate so it is sealed and mechanically held that way. (Mechanical solder is used, designed for attaching steels, not electrical solder). The pump itself is supposed on the other metal bracket and bolt, so this should hold up OK.



Radiator is just about ready to connect. I just need to mount up the power steering and transmission coolers. The heater lines are straight forward, just needed a 5/8 to 3/4 reducer for the return line.



The lower hose I found a premade part (gates 20931) which has the 1 3/4" on one side to match standard radiators and 1 1/2" on the other side to go onto the 1 9/16" on the engine. And its the perfect shape, just needs to be trimmed a bit.



For the upper, I have this bit from Jags that Run.. one side is 1 9/16" to match up with the 1 1/2" on the radiator (conveniently, the hunk of extra cut off from the lower can go here), and then the other side is 1 5/16" which matches the engine. And it has a barbed fitting where I will run my steam line. Speaking of which, the steam line fitting I have connected to a hose ready to hook up. I got the throttle body coolant lines removed as well.



I also got the exhaust y pipe coated, and got some copper gaskets and bolted that all up. Fits perfectly, very happy with it. O2 sensors are in, although the stupid plugs are STILL wrong. I think I might just fudge the connectors and make them work. I cannot find the correct sensors to match my harness at all. And don't want to drop another $150 on more sensors.




So, things remaining to do before starting the engine:

Torque converter bolts
Trans dipstick
Hook up radiator
hook up PS cooler
hook up trans cooler
tighten bolts on trans and t case
Install shifter
Connect battery wires
new serpentine belt
install starter
install new fluids and oil filter
connect intake & MAF

Why the dual pickups? As soon as one gets high it will suck air.

Those are special pickups that close when they suck air. So as long as one is in fuel, it always draws fuel, no air.

Because the tank is long and skinny, they have a reputation for sucking air at angles. So I have the two pickups in opposing corners. Lots of people use these pickups on pirate and are very happy with them.

Well I learned something today. What makes them close when sucking air?

Read the above at auto performance. I think they explain how it works.

All I know is lots of people use them and they are well liked so I figured I'd try them.

I spent a weekend messing with the stock style tank trying to make it fit and it wasn't working well. I also got rid of the tank underneath, which was a huge rock anchor for me. It was bending the crossmembers that the skid was attached to, due to taking the whole weight of the vehicle on it. Since its a scrambler, its got an extra 2 feet of cargo area, so having the 12" wide tank back there isn't hurting much.

Send me the p/n of your sensors OR the connectors on your harness and I'll take care of you.

Thanks, I'll try to figure out what the heck I have. The harness should be newer-ish, since it has the 2 wire alternator plug. The motor is *supposed* to be a 2007 L33 Gen III from a 'classic' silverado. I've found the alternator was not right, there was only one exhaust manifold with the O2 still in it, it was a square style. So I don't know what the harness is from. The O2 sensor plugs on the harness are trapezoidal. I got some for a 6.0 application, but they are keyed different.

Bah..

Here's the connectors and sensors I'm trying to figure out:

My engine harness is this, so it needs to match this:



The sensors I got are these. Seems the keying is backwards. I could just cut the keyways to make them match. But I just don't know if all of these sensors are the same or if they all have different curves. I would think they ar mostly the smae but then way have so many different plugs. I've found at least 5 different plug types in these trucks.

Looks like my harness has the rear O2 plugs, not the fronts...

Looking into things more, all of these sensors are electrically the same. So I'll just make sure that each of the 4 wires goes to the correct place on the ECU and I'll be fine...

I think I should be good now. I just need to make sure the wires are going to the correct pins and it'll work find, if not, I'll move the pins as needed.

I just wish Jim's would have told me he was using the rear O2s, not the front O2s, and I could have got the correct parts. That guy....
