I have seen different things discussed, like welding up some
pieces custom, using a plumber's nightmare of 2 different
barb fittings and a connector, the mythical fuel filter with 9mm
inlet and 7mm outlet. What is the best way to deal with this?

Thanks,

John

OK, so I am running carbs and want to locate my fuel pump and filter up front.

I figure I need one steppen hosen from the tank to the filter and another steppen
hosen from the pump to the fat tunnel line. Then, sigh, I need another steppen
hosen from the fat tunnel line to the short fuel line in the engine bay.

How long are the steppen hosens? Are they long enough to lift out my tank
so I can change the fuel filter? I also kind of like the idea of mounting the
filter and pump next to the spare tire so that they are easy to service. Are
they long enough for that?

Finally, is it safe to use brass barbed fittings like this with fuel lines?

I have a buncha 5/16 and 3/8 barbed fittings I could use to make adapters.

This would let me make the hoses the length I want. I would solder the
fittings to prevent leaks after reading all the posts about fuel and teflon
tape, etc. not mixing.

Sorry for all the dumb questions, just trying to figure this out.

Thanks,

John

1) Get a filter that has 3/8" ends.
2) Change the fittings on the pump to 3/8".
3) In the engine comp. put a 3/8" fitting on the pressure regulator inlet and a 5/16" fitting on the outlet.
If you can do all 3 you won't need any step hoses or adapters.
