Fuel line on 98 STd.

[Rusty Pipes]

Hi all, this may be my first post. I am going thru my, new to me, 98 Std. Belts, rubber, brakes, carbs, fluids, all the normal stuff that one need to look at on a used bike. Bike has 9,700 miles. I am currently riding an 86 GL1200SEi that I restored last summer. I do know my way around a tool box.

Anyhoo. I am putting a Pingle petcock and Dan Marc fuel valve on the bike. When I bought the Pingle, I also got the Pingle in line fuel filter w/ replaceable element. I don't think all this is going to fit on that short piece of fuel line between the tank and the T. Can I make a loop in the fuel line pointing down, so I have room to put the filter at the bottom of the loop? Plus that will give me some slack when removing/installing the tank. Will this setup cause problems with fuel supply to carbs?  Fuel starvation? Thanks for any info...Rusty Pipes

You will starve it in less than 1/2 mile. Must be all down hill from tank.

Also the additional filter is not necessary. The screen on the Pingel works just fine.

I don't even think a dan marc is necessary. Still won't 100% prevent a hydrolock.

Very little in life is 100%. But for $30 a DanMarc valve is money well spent in my opinion. Yes there is still about 6" of fuel line and the fuel rails after the valve that could potentially flow into the carbs. My thinking on that is it is unlikely. As an example if you put a straw into a glass of margarita and put your finger over it and lift it up, it will not flow. I am more concerned with the possibility of the petcock failing badly and fuel flowing down the vacuum line into #6.

FWIW, I've had a manual Pingle, inline filter, and a Dan Marc installed on my ride for at least 10 yrs., maybe longer. Nary a problem as long as there are no low spots in the line.

So, no loop, straight fuel line running down hill as OEM. Filter not needed. I'm not going to get into the Dan Marc/Pingle discussion, I bought them, they are going in.

Another question, I am currently reuniting the carbs into an assembly. When I mate carb # 4 onto #6 they will not go completely together on the dowel pins. There is about an 1/8" gap. I find that the butterfly arm on carb 6 is hitting carb 4 sinc adjuster/flying spring arm. I can see wear marks on both arms so they were running like this. Someone has been in these carbs before. Has anyone here seen this interference before?  Thanks again folks.

 People successfully install external filters in this application often, yet people still say it can't be done? ???
Search the board you will find that two of us in the last two months have installed external filters without any issues even on reserve, and if you think about it what happens to the fuel when you accelerate, it all goes to the back of the tank where the petcock is, so I'm not sure full acceleration is a valid test? 
I do not run a sock in my tank, if anything happens to it (restriction) while on the road, it's not something you can easily fix. I can change my fuel filter in 15 minutes, plus it's clear and I can tell if it's getting fuel and if the fuel is seriously contaminated.
The sock on the stock petcock of a Valkyrie is not adequate, two of my carbs had debris that affected their low speed performance, yet the carbs were pretty clean when disassembled and the tank looked pristine.  Peace-out...
There is even a 90 degree fitting in my fuel line;
