Anyone got a grumpy slingshot dummy dual filler

[MooreMatthew]

As per title wanting to know measurements of where you could place a filler cap 

the diameter and depth 

wanting to convert one to have 2 caps and weld to a tank instead of how he advertises them 

cheers

Ally tank or steel?

Guess it'll be aluminium tank on his Harris

I’ve made a cad drawing just awaiting the fuel caps to turn up to double check measurements before I finalise the drawing and see what the cost is going to be

It is not a twin filler tho..... one has clear plastic, so you can see how much fuel you have, without taking gloves off to open cap.

Might be a good idea that with there been no gauge and a turbo on bike 

drop me a message i then know price of that option over the way I was having it made

Steel tank one is 250....ally tank one is 300.... weld in bits for tanks and filler bolts to it.....
