I saw that, threw me off for a minute. Maybe a sign of things to come for Fred?

Yeah I recall him saying a while back though. "I'm not going any lower than what I am now. Maybe just another inch." That's how it all starts man. I think it will look killer like the avatar with the LS in it.

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

It won't be going any lower than what it is right now for a while. I can't, unless I want to lower the depth of my oil pan! Maybe another inch in the front, but that's all! I do plan on swapping the rear suspension out for the trailing arms in the next couple of months. The rear ride height will stay the same for now.

I am going to get the LH8 oil pan kit though and stick it up in the shop attic. It's a good price right now and will only go higher. I plan on buying a new truck next fall (2005-2007 range), and after that I will start back hard core on Fred. Plans for then are:

* ext paint, darker red
* new carpet, paint the int, maybe newer seats, new glass and tint
* rebuild the front suspension
* spindles and springs, and probably lowering springs for the rear
* wheels and tires. Most likely 17" TT2's
* new exhaust w/Magnaflows

I want the ride height to be were there is about 0" to 1" of gap from the top of the tire to the top of the wheel well.

And if the engine is out to R&R the pan, may as well do a cam, head and converter swap. That's a maybe, but always a possibility. I do also miss my old Whipple blower.....

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

Looks sick in the avatar Bob. I think buying the LH8 oil pan kit now is a good idea. Like you said, once people start buying them up,price will jump drastically. Cant wait to hear the results from the dyno tune.

Nice PCM box there Bob. I forgot to ask you sir, Did Jessie at W4M Perform lock the tune on the computer? I take it he didn't since your having it Dyno- Tuned.

I'm jealous of Fred, Really nice ShoeBox!

Thanks Justin!

Jesse's tunes are done on his license that he paid for. So when I get the dyno tune done, I will be buying a new license as part of the cost to do it.

That computer mount looks real nice man!

Dumb Question: so was the computer mounted under the hood on the newer truck? I assume so since the wiring harness comes out the front left of the engine. I also assume you put it up towards the front to be in a cooler area. Is there anything that needs special attention, weatherproofing wise?

So it is Locked then. When I take my truck to have fine tuned, I will need to buy a license to get the Local Dyno Shop to even touch it? Guess I'm confused about this?
Just asking Dumb questions!
This is my first attempt with EFI.

Yes, it was mounted right below the battery. The two connectors are weatherpac-type plugs. The connectors themselves are not covered or sealed in OEM form other than a splash shield.

The Pin Plugs Have a gasket sealing the Connectors. I think that's all it needs. My '05 Duramax is mounted Right on the Engine. But I would mount it away from engine Like Bob did. Heat or not, Think it would be wise to keep it cool!

That's my 2cents!

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

Yes, you can run the feed and returns between the tank and pump with regular FI hose and FI clamps. That's how mine is set up.

Using the inline pump on both tanks..... personally, I would not. If I were to try that using inline pumps, I would use a separate pump for each tank (mounted as close to the tank as possible), into a separate filter/regulator for each tank, then through one-way check valves, then through a "T". Then when one pump is powered, it flows through the one-way valve, through the "T", and on to the engine, and any fuel that turns around at the "T" will hit the other pump's one-way vale and prevent back-flowing into the other tank.

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

someone on here (Dirty Larry??) is running dual tanks with one OEM style in tank pump. He has a transfer pump to transfer fuel from the one without the pump in it to the one with the pump. He has the pump hooked to a switch and he just flips the switch on and watches the gas gauge as to when to turn the pump off, just another option...

Eeks, that's kind of scary. Get distracted for just a couple seconds at the right (wrong) moment and ..... unless there is some sort of safety cut-off switch involved.

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

man I am sorry for asking too many questions,,, but this is only my second engine swap and the first one was 350 to 350.. but I am lost on the fitting world... I have a one line fuel line to the engine .. but I am lost on what fittings I need,, I was going to order some braided -6 an line and one of this
http://www.jegs.com/i/Aeromotive/027/15117/10002/-1 or one of this,http://www.jegs.com/i/Aeromotive/027/15118/10002/-1 to hook from the fuel rail to the braided line, then I guess one of this http://www.jegs.com/i/Aeromotive/027/15103/10002/-1 to hook from line to filter/regulator. then I dont now the right fitting from the pump to regulator since I dont have the pump,, on its web page it said its out put is 10mx1 but not sure... let me know what you guys think,,, and if I am asking too many questions let me know so I quit hacking this thread .. thanks in advanced.. got to go drive another 200 miles,, I am out

, man is hard trying to figure out what I need with out actually looking at the truck and fuel pump

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

Let's start at the engine and go backwards:

The connector for the fuel rail:
-6AN Fuel rail adapter: RUS-640850, $16 (summitracing.com)


The fittings for each end of the SS braided hose that runs from the fuel rail to the filter/regulator (F/R):
-6AN Straight Hose End: SUM-220690, $4.88 each (summitracing.com)


On the discharge (engine) side of the F/R:
3/8" x 12" Double End Male, Dorman 800155 (rockauto.com) You will cut this in half and only use one piece.

-6AN tube nut, RUS-660570, $3.00 ea (summitracing.com) Pack of 2

-6AN tube sleeve, RUS-660650, $2.50 ea (summitracing.com) Pack of 2

-6AN coupler, male/male, RUS-660350, $3.50 ea (summitracing.com)


After you cut it in half, clean the cut end real good so there is no burrs. The end with the lip will push and lock into the F/R. You will also need to flare the cut end. IT MUST BE DONE WITH A 37° FLARE, NOT A 45° FLARE!! On the cut end, slide on the tube nut, then the sleeve, then flare the end. If you can't find someone local who can do a 37° flare, let me know. You can mail it to me with the sleeve and nut and I will flare it for you.

On the inlet (tank) side of the F/R:
Feed:
Fuel fitler adapter 5/16", Dorman 800120, $6.30 ea (rockauto.com)

Return
Fuel fitler adapter 3/8", Dorman 800121, $6.30 ea (rockauto.com)


On these two ^^^ you will run the FI rated rubber hose and use the FI rated clamps.

The 10m fitting on the pump is the equivalent of 3/8".

While we are talking fuel delivery, how does the EP-381 pump mate to the sending unit, both for fuel and power?

Re: Glock's new project: "Fred" w/ 5.3L LS swap info

Bob looking at the pics of your fuel set up.. what if I used the EFI hose fuel line with EFI clamps like you used , but use that same line and claps to run the line from the filter to the fuel rail... sorry just trying to make my application the less complicated possible. thanks
