Briggs & Stratton Fuel Pump Vacuum Tube Repair On Lawn Tractor




What do you think about this video?

Liberty Patriot: that's fine if you have a new hose, have you tried to clean the outside of the hose and cover the leaks with silicone RTV sealant instead?

Tim Pearl: i'm hoping you might tell me the horsepower of this model briggs 243431 1132-01 90031414. it is missing the sticker that tells the ratings and this biggs is very big bigger than the 13 hp than i have in my garage unsure if it is 16 or 19 hp and it is on a home-lite 5000 ac 2500 dc generator

Aaron Kirleis: wow could they make these any cheaper...jeeez..great video..on this small tube

the1realanalogman: Great tutorial! 

mike cecil: what does valve adjustment have to do with fuel pump or carburetor problems

donyboy73: i would replace the diaphragm

Jeremie Wells: I have a 21HP, single cylinder Intek Plus engine that my dad purchased to replace a twin cylinder engine. The valve cover does not have a hole in it for the hose. Do you know where the vacuum line connects on such an engine?

andrew kelly: i got a ? i have a 18hp ohv B&S engine in a lt2000 craftsman rider it does not like to cold start is there any way to make it start easy because i use it to plow

donyboy73: @ncrdisabled i'll have those poulan numbers for the bar on friday's Q & A

donyboy73: @ncrdisabled it's a 2005, briggs 23 hp intek, many other models will have the same setup

timfischer: Great video. I have a Deere tractor which is having intermittent issues getting fuel. I started by replacing the filter. Then I replaced the hose between the filter and pump, which was cracking badly. As of now, the tractor is running, but I'm barely getting any fuel in the filter. My next steps would be to replace any or all of the following: 1) The line between the tank and the fuel filter (big job). 2) the fuel pump 3) the little vacuum hose as shown in this video. Any thoughts?

1972FordF150: Cool video man ! engine sounds good !

donyboy73: @BuhlzI i stumbled across it when adjusting the valves

donyboy73: @th19940305 that's what would have hapenned but i replaced it as preventive maintenance

donyboy73: it can sometimes have the same symptoms, i.e. backfire, hard to start

647762816: Thank you good info.

rameshm2100: thanks for videos. I was able to change the starter gear on my lawnmower following another video of you. now I went ahead and change the oil as well,but overfilled it. then I realized and chaned it again and put the correct amount in there, but the mower smokes now. is there a fix for that or it has to be done by pros. thanks again for great vidoes.

donyboy73: @GatheringSticks thanks dude

Garrett Jdbe: I did the one on my vanguard powered Simplicity this spring

th19940305: wow thats a nice engine, sounds great too. With the bad tube how did it run? Was it like loosing power or something?

Larry LeCover: Just paid $150 (ouch) to have my fuel pump on my Simplicity tractor replaced. I wish I would have seen this video before I had the "work" done. I am now a fan of donyboy73 and will be looking at all your videos before I even consider a repair store!

jonmyers74: hi could you help me with my mower please .its in my vids many thanks

donyboy73: @Mrtocoolforyou12 similar yes

ncrdisabled Submarine vet: How many hp was the engine and how old was it. My friend has a tractor with a fuel problem and he asked me after he rebuilt the carb and still has the same problem. Thanks for the great videos

donyboy73: put in a higher cold cranking amp battery and synthetic 5w30 oil

jonmyers74: my briggs and stratton 35 starts first pull but runs really rough and uses loads of petrol , black fumes and doesnt rev up to fast running like it should . the carb is ok no splits in the diapram , jets clean , and top of tank clean any ideas,i did notice the 2nd gasket was folded on the edge very slightly

Mrtocoolforyou12: the pump has diaphrams like in a chainsaw carburetor right?

crazeyspivey: Now I think I know my mower's problem. I have a larger fuel filter instead of the smaller type, and it is full of gas when I crank her up. After running for 5 minutes, I notice that the fuel filter begins to get more and more air in it, until there is only a few drops of gas at the bottom. Then the engine runs hot and begins to sputter. I replaced the entire gas line to the tank under the seat, but still gets air in the filter. I guess it is this vacuum tube. Finally have the answer-thanks!

donyboy73: thanks

mike cecil: i have a troy-bilt bronco 18.5hp intek ohv its getting way to much gas it tries to fire and i checked spark plug for fire its getting plenty of spark when i take the spark plug out gas comes out the hole.could it be the fuel pump or do i need to have my carburetor adjusted.any suggestions would be appreciated thank you

BCtruck, rebuild, repair,repurpose: It would be hard to spot the crack in that tube unless you knew to look for it. Nice vid. Thanks

donyboy73: @pivotboy63 i would try a new battery and after a new starter

Dnuccio95ZJ: great video dony. quick question, i have a lawn tractor with an 18.5hp briggs opposed twin on it, and even with a good fully charged battery, it still cranks like it has a dead battery. I know you said in your other video about how the valves could be out of adjustment, but this is an L-head engine so you can't adjust the valves, so i dont know what else it could be. weak starter? but the thing is, it was cranking fine about an hour before it started cranking weird

Dnuccio95ZJ: @Mrtocoolforyou12 that part only costs about $2 so its better just to replace it

Mrtocoolforyou12: if theres a hole like that can you tape it or glue it?

alan933: ***ATTENTION*** If the mower has been sitting for a while, it could be that the bladder in the fuel pump is dried out and just needs to be primed again. My brother demonstrated this to me today by sucking on the engine side of the pump and got the gas back into it. It started right up once it was primed. Saved me time, gas , and money by not having to go get a new one.

legoguy5406: I'v got an opposed twin cylinder 18 Hp. Briggs and Stratton engine. We can't get it to start because it won't suck up fuel. Anywhere I should check?

donyboy73: @walkingfreak thanks man

Beau Kemp: Thanks so much for this video. Just replaced my vacuum hose in 5 minutes. Mower runs better, and I don't have to worry about a gas leak! There was quite a bit of gas collecting on the valve cover and getting blown around. Luckily it's on the opposite side of the muffler or things could have been...explosive.

MrPooters17: Legoguy check the fuel filter if it is not that then get an air blwer thing and blow some air in the hole that the gas line hooks up

Matthew Poole: love these vids! Exactly how id do it. and i love hearing the engine run too

donyboy73: a lot of these intek engines need the valves adjusted

GatheringSticks: awesome job as usual.

donyboy73: it is probably near the carburetor on the side of the engine
