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

[glock35ipsc]

I'm not a fan of running that much solid rubber line. You could, and I am at the moment, but I will be replacing it with SS braided line from the F/R to the engine real soon. That's just too much rubber line bouncing around that could get a hole rubbed in it. I have the line from the F/R to the engine covered in split loom, and wrapped in heat tape where it passes over the exhaust. It's one of the things I did that I don't like and will be redoing very soon.

The base of the sending unit holds the inlet end of the pump in place. Fuel hose attaches the outlet of the pump to the outlet of the sending unit. The wiring is plug and play to the sending unit.

Bob,( And everyone here) thanks for posting that fuel line info. I was going to ask you how it was done on Fred. Very helpful links, should be able to adapt it on my blazer fuel system.

Thanks again, You where right! I spend too much time on here now!

Soule, What fuel pump is that? Very nice setup, looks factory!

Thanks

Go look at the pdf file on post #1259 in this thread.

Is that just the FI hose and FI clamps that attach the pump to the sender then?

you are right on the bouncing around with the possibility to get a hole rubbed in it....ok I decided on the Russell 640850 fitting from the rail into a 6 an male adapter , to a 6an braided hose, then at the end of the braided hose I am going to put another Russell 640850 adapter and then the double bead line x 12 that you cut in half... I am going to not cut it and put one end into the russell adapter and the other into the filter/reg.. hope it works lol,, as said before hard to tell since I dont have all the parts in hand

The bottom of the sending unit is like a 'cup' that is slightly larger than the pump itself. It has a hole in it for the inlet end of the pump to draw fuel through. The pump sits in the cup and the section of hose with clamps holds everything in place. If memory serves me correctly, I used a zip-tieacross the pumpt, too. The clamps I used are incorrect and will be replaced.

Great pic, thanks for posting that!

No dyno time today, it's snowing. Only about an inch on the ground, but wet tires and a dripping under carriage = "no dyno for you!!!!"

[menace121978]

Bob that sucks big time... maybe tomorrow?

[glock35ipsc]

Probably not until next Tuesday at the earliest.

[STOCKISH]

Man that sucks. I was watching the weather last night and was hoping it would hold off until late tonight. Hopefully next week will be nice for ya.

[glock35ipsc]

Soooooo, Dave, my dyno guy just called. It wouldn't have mattered if it was 60° and sunny out, it still wouldn't have happened today.

Seems as though he had a slight mishap skiing over the weekend, and broke his face! He just got home yesterday from surgery to have his cheek and jaw put back where they belong! So we'll try again next week, according to him.

[silvereagle07]

That had to hurt.

[STOCKISH]

I laughed at "broke his face" Hopefully soon my friend.

[Butcherboy]

Yikes! That's a tough break! Hope the guy recovers fine. Bob, I just printed your build/parts list PDF file! Thanks for putting that up for us guys!

thats cool ;man. I did get all the fittings.. the hard go get one from the vette filter to the 6 an line I found it locally,here in sa..,

bob you could always send your truck south to tx and me and rongstad could take it to the dyno and then maybe just maybe send it back to you....

[lownfast]

Bob,

my intake was originally dbw but i have gone with a cable tb and two of the the three inserts are missing, i can post a pic if needed, thanks.

Eric - See if you have a Fastenal store near you, they do for sure. But any fastener supply store will have them, our ACE Hardware here has them. They are 1/4"-20 thread.

when I bought my 5.3 it was missing the fans,,, the yard told me to come and choose what ever fan I want to from the fan room, the fans are all label, what do you guys recommend I take? the originals, or could I pick some from like a f body ?

[glock35ipsc]

If you are looking at electric fans, the original ones are too wide. I heard F-body fans will work thought. Can't confirm this however, I'm using the OEM clutch fan.
