Need a fuel line diagram for my Homelite vac attack 2 model UT09834

dirty fuel filter & or fuel tank

go to www.ereplacmentparts.com for a diagram. just pay attention when taking apart. its not hard. even lable parts if you need to. an air compressor will be useful in cleaning. and brake cleaner does good on oily parts.drys quick and leaves no residue.

The fuel line is replaceable by itself, you don't need a new tank. Just make sure you get the same size line or it will leak where it goes into the tank. Any local small engine repair shop should have the line. There are two lines that go into the tank, the pickup line has the filter on it. It not only filters the gas but keeps the end of the line down in the fuel.

fit new pump ad float diaphragms in the carby
the fuel mix has become irrelevant as Stihl have an oil that is a 50:1 oil and covers all ratios and mixtures
do not use any e-mix fuels as that destroys carby components

try some SeaFoam in the gas may help

My Homwlitw Attack ii won't start. Spark plug is dry even after priming more than 10 times. Where so I start? Thanks, Fred

Yours is not a current model and I did not find a manual. The following is an excerpt from a 26cc MightyLite Blower/Vac UT08550/UT08951 "Operator's Manual":
This product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean 1 gallon container approved for gasoline.
Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use.
Mix Homelite Premium Exact Mix lubricant with gasoline according to the instructions on the package. If Premium Exact Mix lubricant is not available, use a high quality synthetic 2-cycle engine lubricant, mixed at 2.6 oz. per gallon (US).
Do not use automotive lubricant or 2-cycle outboard lubricant.
NOTE: Premium Exact Mix fuel mix will stay fresh up to 30 days. DO NOT mix quantities larger than usable in a 30 day period.
PREMIUM EXACT MIX (50:1)
GasolineLubricant
1 gallon (US) 2.6 oz.
1 Liter 20 cc (20 ml)

1 quart fuel:3/4 ounces of oil = 1 Gallon fuel:3 ounces of oil or slightly less than 43:1. Not what a current manual recommends.
If properly adjusted your blower will operate fine on 50:1 regardless of what the manual reads. HTH

#1 senerio
Fouled spark plug
ie, carbon and or fuel fouled
install new plug, and withouth choking or priming, pull 4-6 times while holding the throttle at wide open.

If not fouled, go to senerio #2

#2 senerio
Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
5) replace gaskets/diaphragms
b) use a spray carb cleaner to clean jets, holes, and body of carb

Yes it will use a fuel mixture of 40:1(3.2 oz of two cycle oil to 1 gallon of gas). Any fuel sitting over 30 days now is considered bad fuel. All the manufacturers schools this year and told us this. We are finding it to be true.
Good day.
