Hi yes you can put a fitting on the boat in the deck or side of top structure above deck then you use a hand or electric pump to pump the gas into the tank.

Hi Mario
I hope this picture helps with your fuel set up on your 520, this is what I am going to use on my 520 Mart Apache.

Bob.

PS the WHITE LINES are what WD200 send me.
Mario this fuel filler is from Tom Lorenze Germany this is what I use, you will need a hand pump to use this ok.

Thank you very much Bob<span class="hps">, i have this plugs (photo) from mhz, but i will need that hand pump you are talking about, where i can get it? do you have it? another question, where do you get that splitter (carb1-carb2)? thanks again.</span>

Hi Again Mario
here is a picture of the fuel pump that you need, make sure you get one that is ok for GAS the nitro ones dont use ok, you should be able to get these somewhere in italy but I dont know any shops there !

you must also use 1/8 tygon yellow gas pipe with the pump dont use anything else ok.

The brass splitter I made myself but you can also use a "Y" connector from most model shops.

Bob.

Thanks Bob, the only thing that i don't understand is tygon yellow, the color is important? is the yellow one a special material? thanks

Yes tygon is a different material not silicone which desolves with gas.Actually the pumps are the same least the ones ive used are same as the ones the nitro guys use,im still using the same one 4 yrs later but you need to swap the lines to tygon or you can use the clear stuff from the mower shop .

Thanks Mart, check this out http://www.modellbaucenterlorenz.de/...products_id=39 is this good too? i ask you becouse i have to order some items from here, and if this pump can be ok, i add it <span class="hps">to the list, thanks.</span>

Hi Mario
Something has just come into my head since you ask about the tygon fuel tube, have you used gas engines before ? or just nitro ? you will need to mix at least 8 oz of 2 stroke oil to 1 gallon of gas for the S520 Engine ok.

Bob.

Looks like the same pump to me,pretty sure the internals on them are the same wether gas or nitro,just need to use gas lines for the fuel.Ive never had any problems with the one im using and it was sold as for either fuel same as the one i linked.
Mart
ps yes also make sure your motor has tygon fuel lines,silicone for water cooling though,pref large bore 4 mm int diam

Yes that pump is the exact one we use here in the states. As already mentioned use tygon instead of the line it comes with.

Thanks guys, surely i will get that one, i found this one here in italy http://www.readytowinmodels.com/prod...1=12&amp;c2=24 what do you think? and this electric version? http://www.readytowinmodels.com/prod...1=12&amp;c2=24

Hand pump works just fine just keep it simple .
Mart

Ok, i will take your <span class="hps">advices.
This are the exhaust pipes i will use, still don`t know if i put 2 (<span class="hps">one on each side) or 4 like the white apache in the picture.</span></span>

Hi guys, here is my new radio, i know most of you don't like spektrum brand, but i allways used it and i'm satisfied, now i'm waiting for the famous mr3000 marine reciever that some of you <span class="hps">recommended. This boat has been tested with to different radios, the new dx3s surface and with a futaba 12fg air. it worked fine with both radios, hope works fine with this one..</span>

Hi guys, i started with some work in the boat, the first is change pilots and <span class="hps">improve</span> <span class="hps">the aesthetics, like adding seats, <span class="hps">dashboard and others, one doubt i have is if i should paint the seats or leave it black, what do you think? Then i installed one of the <span class="hps">fuel caps and <span class="hps">disassembled all the <span class="hps">sterndrive, now i have to close all the stern <span class="hps">holes ( look pic) what should i do? take it to the body-paint shop? or try to do it myself? if you think that i have to do it myself, tell me what material and putty or fiberglass i should use, remember that the inside part of the stern is a <span class="hps">layer of</span> <span class="hps">reinforced wood, thanks.
<span class="hps">regards
</span></span></span></span></span></span></span></span>

Hi there, some working progress, next step is place the exhaust pipes.Regards

Thanksrcguy1411,ok guys,the stern is almost finished, only remains to place the special ventilation grid i took from wd-200, here are some pics of the last work, the exhaust, hope you like it.
Regards

Hello guys, it seems that nobody is interested in this project...anyway,i<span class="hps"> bought a special ventilation grid from WD200 and i have to say something to Matho, <span class="hps">the same thing</span> <span class="hps">I said to</span> W<span class="hps">erner, i can`t believe how you german people work, i <span class="hps">can only</span> <span class="hps">congratulate you for the</span> <span class="hps">quality,</span> <span class="hps">dependability,</span> <span class="hps">seriousness, </span><span class="hps">delivery</span> <span class="hps">speed</span> <span class="hps">and cure of</span> <span class="hps">packaging, thats why Germany is <span class="hps">ahead from the other european countries, very different mentality, congrats again.
Here are some pics of the grid.

Regards</span></span></span></span>

Looks neat. been waiting for this one to finish

Very Nice ........ I like the grille ......... Lots of us are watching........... 

Thanks guys, like the description of the video says, the first stage of customizing is almost finished, remained <span class="hps">sand down the</span> <span class="hps">air vents and place a yellow sheet under the grid so <span class="hps">the words</span> <span class="hps atn">"</span><span>Team</span> <span class="hps">Apache</span><span>"</span> <span class="hps">remains yellow, next step is starting with the cockpit mods, thanks
