Still freaks me out we're putting an electric motor inside tank full of flammable fluid!!

Gasoline itself, does not burn. It's the combination of gas and air that burns. As long as the pump remains submerged, nothing is going to happen.

Yeah, we all know that, but it's just still scary. My high-school shop teacher showed us that. Threw lit match into bucket of petrol!!! I think 1/2 of us were out door before match even touched down!!!Made >psst< noise and went out

BTW, is that filtre rated for 50psi?

Thank you for bringing this up... Turns out you were right 🙏 that plastic filter was only rated for 30 psi 🤦

(but I did test it, and it pulled to redline just fine... (in 1st through 4th anyways)

But it wasn't right & I didn't want to have to worry about popping it 💥 or my motor again...

So I present V1.3 (now in metal with new & improved 60psi Burst rating) 😜

This is the napa gold 3033.
Only $4.34 🤑

☝For the record. I was looking for a 10 micron rating....

but after reading through this informative thread on a Ducati forum

NAPA 3032 fuel filter substitute

And looking through the extensive "Vehicle Fitment Guide" list here 👇

https://www.napaonline.com/en/p/FIL3033?impressionRank=1

I would think it should be more than sufficient 🤷 whatcha think?

And after removing more plastic in some areas, while adding 'structural' plastic welding to other areas... Much to my surprise, V1.3 slid in the easiest 🤷

got any photos of the inside of the original housing

Not sure if this is what you were looking for?... But this is all that's left of my original plastic housing.

For V.2 maybe design can be made more compact by using copper tubing and gas tight fittings?

Not sure about compatible filters....

I think V2.0 needs to include tary's suggestion in the form of a radius bent tube over the top instead of the rubber hose.

 

[Wesley S]

can we just put filtre on outside of tank like on carby bikes?

I also looked even closer at this option as a plan B Incase the Napa 3033 wouldn't fit in the tank...

There is a small spot here 👇 above the starter, below the CCT & kinda behind that coolant hose...

You would just have to use a filter with inlet and outlet on the same side... Something like this 👇

And the lines should lay in fine something like this

My biggest concern with moving the filter outside of the tank is HEAT. I'd be afraid of causing the gas to vaporize after riding and turning the bike off. We know the starter takes a beating from the heat so mounting it above the starter may lead to more problems. I think your in tank solution works great. It would just be more refined if you used tubing instead of rubber hoses. The tubing would also eliminate any after filter contaminate concerns from the hoses and make for more secure connections.

Yeah, keeping stuff away from heat is major concern. Lots of people line bottom of their tanks with gold-foil to keep heat out and it really does help. You should be fine with internal filtre.

Good thing you swapped out that Microgard filtre. It's a private generic brand made for auto-parts stores and are of very low quality. Everyone I know who've tried Microgard oil-filtre has had problem with them leaking right away. Typical engineering practice is to select max-spec of roughly double average operating loads.

The bottom of my 2006 M109R's tank has some kind of metal foil type coating on it, same with my 2008 B-King. It also has the same type of material under the tail, I presume to keep the heat of twin tailpipes from melting the plastic body work. With the YUGE stock mufflers, it may have been a problem. With the much smaller Yoshimura on it, I doubt it.

Oh man, try to minimize use of the d#@n hose clamps.

They do need an occasional tightening, as vibration and hose compression over time will demand it.

HTH

Yes, use spring-loaded clamps or diesel/injection clamps.
