Step two (continued)

Was originally going to cut the top of the box at 2”, but went ahead and went with 3”. I like everything about it except how tight it is for the inner seatbelt mount bolts. Thought about how to minimize welding the top section and try to hide how it’s attached, and came up with some inner bolted flanges. Pretty much done with this part for now.

Nice Box

You bet...


Can we get back to posting photos in your build thread, it's getting kind of wordy lately.

Whoa! Epic flex!

 

[PabloCruise]

Ok, I used the bottom bolt off the steering column bracket and drilled the top hole through the firewall in order to mount the gas pedal. Here's where I mounted the TAC on the pass. side firewall. I modified the pedal a lot to fit, but easy to do.

This is a definite "squirrel" moment Ron, but does your heater/AC unit have a air filter? Working on another project and I was amazed at the debris that was clogging my evaporator...

 

[PabloCruise]

@Megadoomer , it has a return line. Been trying to find a fuel rail with only the supply. From what I gather, that truly began in 07 with the Gen IV engines.(?) According to LS1swap.com they supposedly eliminated the returns in 04, but several 04/05 rigs I found at the scrap yard had returns

The engine is on the stand ready to be gone through. At the very least it’s gonna get a timing chain, gaskets, and sensors. Gonna wait and see what the cylinders and bearings look like before making any decisions on a rebuild.

Is there a consensus as to what is better? I kind of like the idea of a return line after the regulator has made the required pressure and the injectors have had their fill.
But I am also kind of old school...

 

[scrapdaddy]

No, it doesn't. The a/c only draws in cab air, but I'm still worried over time it will clog. This isn't on my top sheet of things to get done this year, but still think a filter of some sort would help. These aftermarket fans don't seem to be very strong and pulling it down with a filter might be a problem too.

 

[PabloCruise]

Right? Wanting to find a returnless fuel rail - can’t find one. There’s aftermarket aluminum rails that say won’t work with stock manifolds. They must be a hot item.

Ah, I guess this answers my previous question. Do you just set the pump to deliver the pressure that the injectors want and call it a day?

 

[PabloCruise]

Glad you're still able to fit that stuff in!

Insert obvious innuendo here...

Pablo, they have regulators and fuel filters built together and can mount it right next to the tank, so you only have one fuel line running up to the motor. much safer. These motors like 58 psi fuel pressure and those regulators are preset for that.

How's this for visualization....

Ah yes, I think I remember they only pull cabin air/recirc, that should help quite a bit.
I pulled the evap unit on my '94, here is what 25+ years of drawing outside air did w/ no cabine filter:

Then there was light debris stuck up at the top. I am amazed this thing moved any air at all:

Sorry @RUSH55 - hijack over!

Safer how? Not trying to be argumentative, but if you are running pressurized fuel from one end of the rig to the other, I have never thought of a return line of low pressure fuel back as dangerous.

The e46 that we got for the has the regulator on the filter, and return line off the regulator, but that mounts under the driver, so still a little bit of run to go back to the tank.

We need more puppy pictures.

S’ok bro, at least you posted some pics!

I was originally planning on running a return from the engine like LC’s originally came with until Scrappy showed me the regulator return and single feed. To me it’s less plumbing and less hardware to be seen. At this point I’m pretty infatuated with a single line coming up crossing over at the lower firewall and running up to the back of the engine. So much cleaner and out of sight.

Two lines verses one. 50% greater chance of getting a rock puncture, crack, etc. in the return.

I was thinking about it more and I guess you are running lower pressure fuel up to the engine bay than if you regulated the pressure up at the rail.

I always thought it was just a cost savings/weight loss measure, so I learned new things this morning!

Earl.

No. Same pressure either way, the advantage to putting the regulator on the return line is you don’t experience the pressure drop when the volume demand increases on higher performance engines running bigger injectors and pumps.
