    Fuel line ID diameter?

    What size ID fuel line should I use for my G-62? I have 3/32" and am using 1/8" pipe in the tank. I also have 5/32" ID tubing. I have a 3 line set-up which I have always preferred over 2 line. What are your suggestions on size and line? Where would you put the fuel fill and vent tube exit on a Ziroli P-40? I am using Tygon tubing for gas.

    Thanks for any help you give me,

    RE: Fuel line ID diameter?

    NCIS,

    I used the 3/32" line on my G62 and its fine. It gives a tighter fit around the fuel line. Not sure on the Ziroli P-40 venting but I always like to stick a piece of brass tubing in the end of the vent line and then use a plastic landing gear strap to secure the brass tubing to the lower part of the engine box. I then cut the brass tubing at an angle to give it a better look.

    Personally I like to use the 1/8 Tygon for my 50cc engine, I drill out the tank stoppers parts for the larger brass tubing and use the DuBro larger clunk, the reason being, the Tygon is much stiffer than silicon or neoprene, the extra weight helps the fuel line move more freely in the tank

    I've used the 3/32 neoprene for my under 40cc engines and that's fine using the stock tank parts.

    RE: Fuel line ID diameter?

    I also need an inline fuel filter and can'r find one for gas. Everything on Tower is for glow only. Does anybody have the sku number for the inline gasoline fuel filter on the Tower site? I want to get the fuel line through them and if I have to buy from two different sources it doubles my shipping cost.

    RE: Fuel line ID diameter?

    fuel fill I put in the cargo/first aid access hatch. I'd also use a fuel line that the largestt glow fuel
    filter will fit into. you will NOT find gas fuel filters for anything smaller the a 5/16 line. unless you
    want to use a line reducer. btw.. fuel filters don't care what fluid runs through them.

    PS, thought you were going to put the fill in the stock P-40 location.

    RE: Fuel line ID diameter?

    I don't use any of those filters....I do most of my filtering (three times) before the gas gets into the plane. From there a very good felt or ceramic filter clunk does its job, then the internal carb screen does its job. I clean and inspect regularly to avoid being caught off guard with a problem. Adding additional points of failure inside the aircraft never appealed to me.

    RE: Fuel line ID diameter?

    The fill will be in the scale location. I am making a fuel fill and cap for that. I'm using Tygon medium tubing and the Hanger 9 Pro Fuel Filter between the fill station and the fuel fill and from the tank to the carb. There will also be one on the vent tube to make sure nothing enters the tank that way. The Pro Fuel Filter only allows fuel only to go in one direction and caps it off from returning to the tank. That makes 2 filters on the plane both in an easy access area. The bottom of the engine box is bolted into position for strength but can be taken off for engine removal and fuel line filter changes or cleaning. The servo wires for the throttle and choke meet the extensions in this area so they can be replaced easy too. I think I've covered my bases on this part.

    Thank you all for your help,

    NCIS,
    I thought you wanted to order from Tower?
    Put this is the search box, "FUEL FILTERS GAS" there are several there to choose from

    Chad,
    +1,
    I like my fuel clean before it gets into the plane also.
    I use one of those fiber type filter/clunks for a weed-eater/leaf-blower tank in the fuel container, and clean the carb screen at least every second gallon or at any sign of sputtering.
