Hot Rods Fuel Injection line for entire length of car?

Is there any reason not to run fuel injection hose the entire length of the car? Running 32 tank on a 28 Sedan to a SBC.

 

EFI with a pusher pump?

 

More chances of rotting and wear you can't see. Just use solid line along the frame and rubber to tank and to engine like has been done for a long time.

 

From a safety aspect the hose is more likely to be damaged, leak, rupture. And longer pieces of hose can cause fuel pressure changes.

Best to run the majority of your fuel line as hardline.
Leave sections of hose where movement may occur between components e.g. tank to body, frame to firewall, and firewall to engine(fuel rail).

 

^^^ Right on, plus the vulnerability of the rubber to stones and road debris.
I had a friend (Wimpy Worell) whose '32 Highboy had rubber fuel line from the tank to the mechanical flathead pump.
Major fuel leak in 3 days...leaking gasoline ate a big hole in the High school parking lot!
Mr. Mix was on Wimpy like a hot dog bill on Tuesday!

 

Metal line is cheaper and safer.

 

You should have LESS than a foot of hose in your fuel system.

 

I admit to not knowing much, but I wouldn't ever run a rubber fuel hose from tank to engine. I know how my luck works. The first drive I would have a stone or something strike it and rupture the thing.

 

the bigger question is why would you want to?

 

Ok, I'm glad I asked. Is Nicop good to use then or do I need stainless or? It's just a Edelbrock mechanical fuel pump mounted on the engine coming from the 32 tank on the back of the car. Is 3/8" the right size line?

 

This^^^^^!!!! Geez, nothing looks more like shit than 10 feet of rubber hose zip tied to the frame rail. Not to mention that you cant pass tech to race. And if you cant do that why the hell bother? We don't build these things to pick up groceries.

 

I’ve done it on winter beaters and cars I just need running.
But anything I care about gets steel line bent up.

Fuel injection hose is good hose and is layered ( don’t remember how many layers) also if, your going to use it.
Use fuel injection hose clamps.
They don’t cut into the hose like regular clamps do



You can run rubber but it looks shoddy

Nicop is fine
Steel tube is fine also
3/8th is right.

 

NiCop is fine for fuel line, I use it on all the stuff I build.

Nichol Copper or just copper is easy to work with and will not rust . I have used copper on a few gas tank to pumps through out the years . Never one issue . It does pass Safety 23 inspections , or at least it did for years .

 

What pre 65 fuel injection are you running

 

I don't have fuel injection. Was asking about fuel injection hose because I was told it was the strongest and best fuel hose.

 

You want safe for ALL fuels and is abrasion resistant -
Run stainless braided Teflon. No fuel the government my throw at us will damage that..!
I've done two of my cars, will do a third when I get to that one.
Sure, a little more expensive, but it's do it once and forget it..!

It's designed for higher pressures, older EFI systems ran ~50PSI, newer systems are much higher.

It is still not a reason to use it as a replacement for hardline.
FYI BMW hose was the fuel line to use back in the 90's, really durable stuff.

 

The old NHRA rule book I have says 12" total of non-braided or non-metallic line from front to rear. Even if you don't drag race, the fuel system guidelines make sense from a safety standpoint.
