I didn't, unfortunately. However, all I did at the sender was use fuel injection rated hose and clamps, 3/8, 5/16 & 1/4. I can take some photos of the connections on the cross member under the cab tomorrow, if that will help. I made all my connections there so if I had to drop the tank I could easily do it there from a creeper instead of taking the bed off again.

That would be good. What brand of fuel line did you use?

Re: Nylon Fuel Lines

On your last pic, the line that goes from the filter to the motor, you have steel line, then a connector, and then rubber? I don't think that connector is meant for rubber....i'm pretty sure its only for nylon tubing.

EDIT** Looking again, i'm thinking that's the fire sleeve over the nylon tubing? Is there some inexpensive alternative to that fire sleeve stuff?

Re: Nylon Fuel Lines

I found a factory line from the fuel rail to the frame. At the fuel rail it is about 6-8" of flexible nylon (or rubber?) and then to steel. At the frame, it changes from steel back to the flexible nylon (or rubber). Both ends of this line have that female fitting that requires the steel tube with the fancy gm flare.

Re: Nylon Fuel Lines

Blake is that regulator adjustable? Everything I have read from dirtylarry says that bumping up the fuel pressure really makes a huge difference in the way it runs.

No, it's not adjustable that I know of. I did use Larry's experience and put in the pump he ultimately went with. If I remember right it was the same pump used in a '95-'99 Tahoe/Suburban. It worked great on the two road trips it has been on. Plus it pulled an extremely heavy trailer up two heavy duty grades with no issues at all.

Hope that helps!

Re: Nylon Fuel Lines

I ran nylon line from SUR&R on my Suburban LS conversion

http://www.surrauto.com/fuel.html

They make really nice and easy to work with lines, fittings, and clamps. I can take pictures next time I have it up in the air next week
