Technical Fuel tank plumbing question

Question about how your connecting fuel lines to your fuel tank:
I see a lot of guys running hardlines for their fuel from the tank to the engine, but are you connecting the Hardline directly to the tank? Or do you connect it to a small section of flexible fuel line that connects to the tank?

I don't expect any tank movement, but I wanted to check before I plumb this whole thing in.

Thanks

I used hard line coming off the top of my RPU tank and then I ran it down to just through the bed.
Then using the proper fuel hose (Gates Barrier) and fittings I made a short flexible hose to connect it to the fuel line on the frame.

There is another similar hose up front going to the fuel pump.
There are no hose clamps in my system.

 

Hard line direct from tank is the norm.

 

You only need flex line when you have movement of one part or the other. So under normal circumstances just flex line between engine and the line. Unless the tank is rubber mounted and can move.

 

You used some nice pretty fittings and everything looks good.

 

I like some flexible line between the tank and the frame. I seems most newer vehicles are that way.

 

That's a clean setup. Thanks

The idea was not so much for movement as there will probably be very little.
Future disassembly however is a consideration and the hose and fittings make that much easier.
It’s called planning.

 

I went with hard line from the tank to the frame up to the engine area, rubber fuel line from there to the engine.

I don't see how have a soft line from the tank to the frame will make removal of either the tank or the line any easier.

 

Nice job! Your not concerned running your fuel line over the exhaust? Probably not a lot of heat back that far anyway..

 

Depends on how the tank mounts and dismounts,
Can you remove the lines with tank in place?
If no then you need some flex

 

Short hard line from tank to main line via an inverted union is also another option for accessibility.

 

Tanks recommends using a flexible line between the fuel tank and the frame , i have always done it that way. not saying you will have problems if you don't

as for running fuel lines over the exhaust...i have always planned it so no fitting is directly over the exhaust. if a fitting has a small leak it won't drip on the exhaust

just my 2 cents

 

That would be understandable since not everyone would make sure to not have stress at the point of connection.

 

My plan is to be able to remove the tank and then since the hard fuel line runs through the metal bottom of the bed through a tight fitting grommet , consider what would have to be done if the bed needed to be removed for some reason like repair etc.
Trying to explain this stuff is getting somewhat frustrating

 

The fuel line is far enough away from the exhaust, and the exhaust is ceramic coated which helps it run cooler than uncoated.

As for leaks, there shouldn’t be any with the good inverted flare fittings.

 

Hard line all the way with flex line on both ends. Easier servicing if & when required
