Well I have been on the phone with a couple guys today dealing with brake lines and fuel lines, no one can give me good answers.:willy:

First Question: question is can I run a stock replacement fuel line? If not what Size do I need?

My engine -Fuel Injection TBI 350 SB Chevy. Pretty mild 325HP or so.
What do I need? This stuff is all spanish to me!

Second Question: What type of brake lines do I need to run with my set-up? (I need everything: Parking Brake cables, brake lines running from calipers, and the main brake lines)

My Brakes -Manual C5 Front disc brakes, 85 camaro single piston rear disc brakes. I am using the CPP mastercylinder/proportional valve.

Stock fuel feed line should be fine for that set up. What I don't know is if that EFI set up requires a return line or not. If it does then you will need to add one.

If you have not called Classic Tube yet, do it. They can modify stock lines for custom applications and was helpful when I talked to them several months back. I would not call Inline Tube. No help and do not make custom lines.

Stock brake lines will be fine for your application. Obviously you will need some type of adapter to go from metric to standard on the C5 caliper and probably the rears...easy to do. You will also need an adjustable proportioning valve for the rears to get the bias correct.

If I remember correctly you are running a fuel injection unit so you will need a return line. You can run a 69 SS fuel line for a 350 motor as from the factory it had a return line...then just cut the feed line where you want to run the pump.

Trying to make it easy from a bolt on standpoint. You can bend your own lines and run them where you want but it is a pain in the ass.

Ok this is a series of more dumb questions:

The return line runs from the engine to the fuel pump? or sending unit?

What I am going to do is run an internal fuel pump on a custom built tank.

Will I need the 69 camaro Sending unit (3/8) with return on my tank?

QUESTION:
The fuel line runs from the Internal pump to the engine on the main line,
Then their is a return line from the engine back to __________?

Sorry for the goofy question, I am just trying to visualize this so I get it right when ordering this stuff up.

Who is doing your tank? Look to the left under Ricks Hot Rod Shop as their tanks are first rate and run a very big Aeromotive A1000 pump. That is what I have and I can get you some photos if you like. 21st CMS to the left also does tanks in aluminum and stainless.

All of your questions depends what the answers are to other questions, is that confusing enough.

If you are going to use a stock tank and modify it, depends on if you are running an intank pump or an external pump. The easiest thing to do if you are modifying a tank and it is a low horsepower deal is use an inline pump and a stock pick-up and sending unit for a 69 ss 350 car as the return is built into the sending unit. Make sure you vent the tank or use a vented cap.

The draw back to using an external pump is heat(pump getting hot in traffic in the middle of the summer) and noise but ease in service.

Intank pump will run cooler, quieter and a more clean installation, but a PITA to service as it involves dropping the tank. Also not the easiest to put into a stock tank.

Hard to baffel a stock tank so fuel slosh/starvation is a problem if you are going to go screaming around corners.

I believe on one of Mark Stielow's cars he put a sump in a stock tank and used an external pump...may have been the Red Witch.

Not sure if this helps are not.

That helps quite a bit.

What I am planning to do is build a tank similiar to John Parsons tank that he built for his too much project. I am going to fab the tank up myself. I wasn't planning on sumping the tank since I was running the internal fuel pump. I may check out the aeromotive pump if you believe that is a better route. I don't mind internal pumps because I really don't see myself dropping the tank too often and I won't be taking the car out on the track, just long hauls and cruising around.

My car isn't going to produce big HP but that is not the reason I building the car. I want something reliable and also halfway fuel effecient. I will consider adding a sump however if you feel this is a good route to go, but I do not plan on using a stock style tank.

Make sure to baffle or sump the tank to help keep the in tank pump submerged at all times. It will be the difference of the pump lasting a long time or not. I believe the return line is 5/16" also.

What Mike said....make sure you baffle
