Title: Installing a new fuel tank - info needed!
Post by: Monster Dave on October 15, 2008, 03:53:31 PM
Hey guys,

Can anyone tell me if installing a new fuel tank on a Monster is a big project? If not, could anyone point me to a "how to" that I might use to install one (or at least some tips).

Thanks!

installing a new one is easy, as long as the years match.

just raise it.... disconnect the fuel lines, remove the pin clip on the hinge..... then do the reverse with the new one.

And take lots of photo's and make a topic up of how to do it in the the How to section   [thumbsup]

It's a pretty easy job. I would recommend having someone there to help hold up the tank while you're connecting the hoses and the pin. No worries.

pretty easy; take your time, label the fuel line connections with masking tape and permant marker; 1+ on a helper / holder.   Guts much more difficult to access and gas cap seal gasket more challenging .... ask me how I know!

Duck painter is a pro; so ask him .... ;D

Hve fun ...and BTW what happened to the old tank?

Thanks for the tips everyone! It sounds like a much more doable job that I thought. If I do it myself, I will certainly post up a how to thread! I should be able to arrange for a helper to hold the tanks if need be. I was really just debating on having a local shop just do it for me, but if it's not that hard, I'd like to learn how to do it myself! The new tank was delivered yesterday, but I haven't had time to check it out yet. My bike is an 03 Monster, so it has the steel tank which means that the pump is outside of the tank - thankfully!!! I just hope the innards are still in the tank.

My old tank is still on my bike, if anyone's interested I'll post up pics of it and sell it for a resonable price - or just PM me. It's got two dings in the right side from the handle bars from when I went down in a recent accident - which was ultimatly minor - thankfully! People drive crazy out here!!!!

Pump's on the inside on all FI bikes.  It was only carby bikes that had the pumps outside. 

If you've got (or get) the DesmoTimes manual it's got a section on the fuel system.  It's mostly going over how to swap a fuel filter - but it does discuss the pitfalls over getting at the guts in the tank.  If you don't have the DesmoTimes manual - it's a handy reference.

Are you sure? That doesn't sound right - I thought that one of the key features that distinguished the steel tanks from the plastic ones was that the fuel pump was moved to the inside of the pastic tank. Even the Ducati Mechanic that I spoke to was thinking that it was that way (they way I thought that it was)....  ???

yuu is right.

the IE tanks all have the fuel pump inside. the Carbed tanks all have them outside where the starter relay is. (someone correct me if im wrong) but the distingusihing difference between plastic and metal is that the plastic ones require you to run the tank dry, dump the remaining gas, and remove the tank so you can unscrew the pump to replace the fuel filter. (lol say that 3 times?)

On a steel tank you can get a stiff wire like a close hanger or a small hand and just reach inside pull out the fuel filter and swap it.

Thats a plastic fuel pump. notice how you cant really move anything without moving that whole assembly.

check this thread for more info.

Yeah - sorry to bear bad news.  I've got a steel tank era FI Monster and that pump is definitely inside that tank... other wise I've got electrical wires running into a gas filled container for no good reason. 

As He man pointed out, there is a big difference in the pumps from steel to the plastics - but that all live inside the thank.

Thanks for the clarification guys. I'll get my first glimpse at my new tank this evening. It is a used tank but not a repaired tank, so now I'm ultimatly curious if it came with a (working) pump in it or if I'll have to swap the one in my old tank.

OK, so I got my new tank which is awesome, but I haven't yet installed it. However, looking in the Monster 620 Dark fuel system diagram in the Ducati Parts Manual (page 81), the fuel pump (2) is clearly shown just outside of the tank below mounting clamp (8).

My new and old tanks are identical to the one in the parts manual; down to each individual clamp, bracket and hose. So I'm confused about why so many people have told me that the pump is inside the tank. Is this a variation in the Dark model only?

The parts diagram is an 'exploded' view (notice how the fuel cap is 'levitating' above the tank). The pump and filter ARE inside the tank. If your new tank is complete, then its plug and play. If not, then you will have to strip out the old and fit in the new. Not hard to do but the filler cap iring can be a pregnant dog to get back in if you don't know the technique, probably best left to a dealer.

Alright, until I get it serviced I'll just take your word for it since I haven't gotten into my old one yet. Can the fuel filters be transfered?

Yes but for the cost involved, put a new one in.

Do they tend to be pretty cheap?

So that line of reasoning leads us to deduce that the fuel pick-up screen (4) is located outside of the tank too then, right?   ;)

(And iirc, the pump is actually the part labeled 1 in that diagram.)

Then what's #12?

I thought that was the filter.




edit:  Wait, is #1 the rubber sleeve that surrounds the pump?
Title: Re: Installing a new fuel tank - info needed!
Post by: Capo on October 22, 2008, 01:29:37 AM
12 is the filter, 1 is a rubber sleeve into which the pump 2 is inserted.

I never realized you could get the sleeve separately.

Should have looked closer.
