Yep, that's what I did. The clamp on the left isn't too bad but the linkage bar is in the way of getting a straight shot to the right side.
Your 37 mpg is 2 better than what I avg no matter what I do besides staying off the throttle but I'm not that old yet

TY. Spiralout:

I bought a set of needlenose this morning with the 45deg. It worked great for the left side hose. The right side hose a straight set worked fine along with getting the clamp on. Was actually dreading those two but they were not as bad as thought they were going to be. Thought of removing the fans...just in case but found they were not coming off the bike very easily. This old 88 is a california bike and the plumbing is unending. That was going to create a lot more work that it was worth. Thankfully the hoses slide on easily and the clamps slide in place. About all thats left is throttle cables, connect fuel line then the air cleaner box. Since I am on spring break hopefully have it fired up later today or tomorrow.

AND I AM TOO OLD!

This is what you need for those hoses.

My 1500s never, ever, did better than 33 mpg....
but then, I always stayed with the fastest traffic on the road

The carb is connected but having problem getting gas thru the petcock. All hoses involving the petcock down to its source is new. But when I crank the bike with my thumb over hose from the vacuum source the amount of pull seems to not be enough to open the petcock to allow gas to the carbs.

Below the sub filter is a manifold with four vacuum lines. One from the autopetcock, one for vacuum source, and two that go up under the carbs. All are tight and not leaking. The autopetcock I installed new diaphragms, springs etc. during the carb rebuild. I do believe it is assembled correctly. Certainly its not leaking any gas.

I am going to examine the vacuum source as its on the intake manifold where it goes into the engine. It might be plugged with something. Or the manifold all these hoses are connected to may have a leak...just a wild guess. This is the reason I finally bypassed the autopetcock in the past. Thinking of running the hose from the petcock directly to the vacuum source bypassing the manifold.

Morning update:
Poured a bit of gas down carbs. Bike fired up and ran with it for what it had. I moved the vacuum hose from the manifold described above directly to the source on the intake manifold still will not open petcock so will tear the petcock down and make sure everything is in place as what I saw in one of the videos I viewed. After that I am dead in the water regarding getting gas thru what is percieved to be connected as it always was. Really hate to bypass the petcock again.

Update to the previous update.
There is fuel going past the petcock. After pulling the downsteam hose from the petcock, keyed the bike on and there is flow. But thinking now very low pressure as I do not believe its filling the carb bowls. Nothing out of the accelerator pump to spray nozzles when throttle is twisted. I know they are clear as I did the test as per Raadakk's test on his website. The exact same problem I had prior to carb teardown and rebuild. I do have another pump. Likely swap it out today.

Got the bike running this afternoon, but had to shut her down. Fuel coming out of the vacuum fuel return valve...at least that is what I think it is. I do not ever remember it having a hose. I will post pictures later of it. No I do not have the bottom of the air cleaner housing on and that alone might be the cause of a vacuum leak. Since this is my first carb rebuild on this type of vehicle. The accelerator pump and nozzles are spraying fuel. That being said before the other valve started leaking it acted much the same way before the rebuild.

Yes the vacuum valve has a vacuum hose to it, if fuel is coming out where it connects the diaphragm in the valve is bad.
