What size fuel line

[ForceFed70]

No one will have that.

You never know, they can make some amazing things nowadays!

are the 428 sending units 3/8 instead of the 5/16" stockers? and are they redily available?

2 types of braided brake lines, dot approved have a plastic sleeve on the crimped ends and the others do not.

I've been reading up on line sizes, and heard that 3/8 (6AN) is good for street aplications, and that 1/2 (8AN) is better if the car is a race car/drag strip car. My 65 is going to be a strip car (only making around 450 hp), but I'd rather not have to run braided soft lines from the tank all the way to the engine bay..?

3/8" lines will be fine for 450hp(and more.) If you are going to run nitrous, you might just consider bending up 1/2".

3/8" lines are available through aftermarket sources, such as CJ Pony parts. They are available in standard steel or stainless. I would use the late 67'/68 type which does not route the fuel line down the drive shaft tunnel, but under the floor pan instead. That could keep you from getting dinged during a tech inspection.

Most aftermarket sending units are already 3/8", at least they are for a 65'/66' Stang. I bought 3/8" sending units from both CJ's (a P.O.S) and Tony Branda (preferred.)

Dennis, you mentioned using the 67-68 line..Doesnt the differences in body styles and engine bay effect trying to put it in a 65 car?

Not sure and I haven't tried it, but I am pretty sure that I saw a post on it in the past. I made up my own line to do the same thing.

Since the cars are very similar in length and equipment, it does seem feasible.

The danger of the driveshaft snapping and then hitting the fuel line scares me a little. Thats the only reason why I ask about having it routed around the frame rail instead. The car is getting a drive shaft saftey loop, so thats at least a little protection against that happening.
