PPE ported fuel fitting vs stock Pics.

[speedy03]

Here are a few pics of the PPE ported fuel fitting vs the stock one. The easiest was i found to remove it was to take off the A/C compressor. It came off very easy. I used a 17mm wrench to take the fuel line off, and a 7/8 socket to remove the fitting.

Stock one on the left. PPE one on the right.

What exactly does this do?

 

[speedy03]

I guess help keep the fuel rail from running out of fuel.

thats quite an increase. couldnt you drill the stock one out though?

What exactly does this do?

Larry, it helps the rail recover a little quicker. Bigger hole to get it in faster type deal.

The hole in the PPE valve in the picture looks way HUGE. I don't memmer the hole in the valve i got or did i drill it? It wasn't that big IIRC.

Thanks for posting pic's speedy.

Are there any disadvantages to doing this?

I think it could be drilled. But not sure. I'd give it a shot.

Heads up Larry, It's tight...really tight.

Move the beer off the inner fender so you don't spill it if your wrench slips.

No drinking while working next weekend, probably not a good idea.

Why would GM make the ID of the stock one so small??

smaller hole holds pressure better.

Kinda like suckin and blowing through a straw, kinda tough. Also kinda like the fill up the air balloon and let it go thing, i think it's an engineering balance between available volume and pressure retention.

I may be dopin' smoke on this one I aint no engineer.
