How do I set my fuel system up?
I have a tanks inc 255 in tank kit, 2000 corvette filter/ regulator, and now I am stuck. What do I do now? What fittings do I need for the filter? No one seems to know what I need. This whole project sucks and I don't know what to do anymore.
Anyone have a complete guide?

Well I used the stock lines on the car they were stainless. Its a 1981TTA, use a inline pump, and put a filter before the pump, and one after the pump. Good luck, I couldn't afford a kit.

Well if you are running the truck intake, I just used the return line off the stock intake which is a 5/16 hose, and the pressure line is 3/8. Got some high psi fuel line for parts store, some fuel quick connect adapters from the parts store, and put clamps on it all. Got the ECM controlling the pump thru a relay. Don't over think it, it's not as complex as some think. Just go to the part's store, and find the car guy in there. They sell adapter the you can hook the hose to that snap to the fuel rail just like the factory ls stuff, take your time, and look around, I also got a book on how to install a LS in almost anything. Did'nt use all they suggested, but it gave me and idea of what I needed.

Most ppl don't mention every detail because they spend more time doing than writing.
To put it in perspective, a return systems comes out of the fuel cell, to pre pump filter, pump, post pump filter, to fuel rails, to fuel pressure regulator, then back to cell. I believe the vette setup work like the return loop in itself. Its the post pump, loop, and return. Here is a picture from a .2second search:
Orange and red are for fuel and return, not sure which is which without one in hand, and left is obviously the rails. if finding the right fittings is the problem take both to a speed shop and ask them what connects.

Also if you got a aftermaket tank setup, it may have AN fitting's. Maybe 8AN, or 10AN, or 6AN. Then you may want to run new lines from the tank, all the way to the fuel rail. If the intake has one line in use the vette filter to return fuel to tank, if you have truck intake, it has a in line, and return line.

Summit sells the fuel hose thats rated for efi. Buy enough of it in 3/8" and 5/16 along with enough fuel line clamps. Run hose from fittings on tank sending unit to the filter/regulator, 3/8 male barbed fitting on output side of filter/regulator into more 3/ hose and route it to fuel rail, slide it on fuel rail with a clamp. Be sure to get the spring loaded fuel clamps, the screw tight clamps arent strong enough. Doesnt get any simpler.

Olly's thread, which has been very helpful to me & many others.

Scroll down till you get to the fueling diagram. It contains just one example of how to connect your fuel system.
Marcello's post above (in your thread) has a pic of the fuel reg. As you can see, it is mounted on the fuel rail at the engine. As your intended horsepower goes up from the stock figure, the more you should consider placing the regulator CLOSER to the engine for proper pressure.
There is much research involved..more so than I had imagined. But I can guarantee you that the answers are all here.

Thanks to arthropraxis for the link.
I chose the Russell push-on fittings. They are very convenient, & look nice.

ha, ha, you're right!
like being stabbed multiple times in your fingertips with braided fuel line!
or, when you're lying on the garage floor, and the little cutoff bits of braided go into the back of your head...and stay there. No matter..they can be pulled out with a pair of pliers.
Oh, the things we won't do to complete our projects!

Guess you havent searched enough cause i have 3 threads saved in my "favorites" discussing this alone. FYI I spent at least 50+ hours researching my project. Dont think you can just search "fuel system setup" and find what you'll need. In many threads I had to read through pages and pages to find the info needed. NO ONE on here has made a thread titled "how to setup you corvette regulated fuel system for engine swaps". The info you are asking for is very basic info anyways and can be figured out by taking some measurements and looking on a parts site.

HAHAHA yea except mine are steel splinters from a cutoff wheel that stab my a$$ cheaks. I could write a book of things that can injure you that you'd never expect.
