Guys while putting my 3200 rpm spring I managed to break a fuel line. Can I cut the bad section, and splice the ends with a piece of rubber fuel line? Or do I have to replace the WHOLE stainless line?

Thanks, Tony

 

Which line? If it was any of the 6 from the back of the pump to the injectors you need to replace the entire line.

BTWDYK Each of the 6 injector lines are the exact length and exact c.c. In capacity or the injectors will not work properly.
That is why some of them are wound up like a broken pretzel to take up the excess length.

If it was the low-pressure line then you will be OK with splicing it.
Be sure to use a hose rated for diesel fuel service.

It is the one that goes to the front of the pump, by where the pump itsself bolts to the front of the engine. Thanks, Tony

Big line kit

 

Thanks ofcmarc, For the time being I used a piece of diesel tolerable fuel hose and clamped it down with hose clamps.

Thanks, Tony

 

That'll work for now. The big line kit is cool, but you should be able to score an original from Cummins without too much trouble.

 

Is there something special about the big line kit? Is it different than the original?

Later, Tony

 

It's bigger and it does away with the banjo bolt on the filter head.

 

The line is physically bigger, hence the name. It uses rubber line and push-lok fittings, I believe. If you're serious about the VE power race, some version of the big line setup is a must in order to supply the VE with the volume it craves at higher power levels. For sub 350HP, stock lines will be OK.

 

I see, I'll keep that in mind for later on. Thanks, Tony

 

My favorite thing about the Big-Line Kit is that it replaces that hateful rigid metal line with a more user-friendly flexible rubber line.

I went one step farther and also replaced the line between lift-pump and filter with a second Big-Line Kit plus a fitting to thread into the lift-pump outlet.

With the Big-Line Kit, you also gain a port for tapping in a fuel-pressure gauge-line, and the ability to add as many extra attachments as you desire, by simply cutting and clamping the hose.

Should you later desire to re-locate/replace the fuel-filter, the job is much simplified with rubber hoses.

Etc. Etc.
