Howdy!
Looks like you got a nice land rocket , we hope to see its revival on the forum too 🙂
Judging by your pictures:
1. The black ones going to the 3-way unit called the Fuel Pump = It will need some clamps / jubilee clips just to avoid fuel leaks, as hoses may swell a little bit under heat.
I will annotate each image you posted below:
2x Black Holes under the tank == Get a 1 meter hose and put it there , this hose goes to the rear tyre , suspension linkage= This is “overflow / breather” , it looks missing. And if you overspill or bike falls (God forbid, that overflow hose could drain the fuel away to the rear tyre , instead of it dripping all over a hot engine and if the coils were arc’ing , that’s an explosion waiting to happen.
Fuel Tap = Small Nipple is for the vacuum and the big port is for fuel towards the fuel filter yes. Make sure to clamp/jubilee clip that port too.
Yes you’re correct that goes to the tank’s fuel tap.
Yes those thin lines are basically vacuum feeds coming from the rubber intake neck boots at the engine cylinders where carbs swallow themselves into.
Also you will 100% need a new fuel filter there, so replace it while it’s apart:
Look at the hole again, if its blanked by the factory, then no need to worry about it. Otherwise it is either Vacuum Feed or “Overflow to the Ground/Road”
This cut hose that looks pointy at the end is mostly likely the “over-flow to the road” , if bike falls on its side or the floats get jammed open, extra fuel will gushing out to the road to save pistons being flooded. Also acts as breather when needed.
Arrow ⬇️ Left black hose , this is “incoming filtered fuel” (so the tank and fuel filter send fuel down this hose as Entry to the pump)
Grey Spring Coil Pipe = > “🅿️” mark on the vacuum pump means “pulse” , aka vacuum as the pump works in a pulsating fashion. So make sure that spring coiled hose is getting vacuum from the engine’s rubber intake neck boots or make anoter T-junction to join the rest of the vacuum lines on the bike.
Arrow ➡️ == right black hose ==> Fuel pumped out towards the carb. This is the fuel that’s leaving the pump going to the carbs.
The pump has also 2 more arrows facing down to the road, ignore them as they have been factory blanked off.
Hope this helps!
