Crafstman GT18 Fuel pump

[Dpregs]

On to the next issue, the fuel pump. I replaced the original with an aftermarket, but if I could fix original I'd like to.

Problem is, one of the barbs comes out. See pic. Do I just braze it back together?

Any advice is appreciated!

Looks like Zamak which is very low melting point. I would use an appropriate epoxy. Don

 

[Dpregs]

I thought epoxy, but didn't know what effect gas would have on it.

Get a fuel tank repair kit and use the epoxy from it.

found my answer: My google foo was off last night.

Is J-B Weld resistant to water and/or gasoline?
When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld.

I have one that I JB-ed several years ago. Still holding up.

 

[Dpregs]

WaterWeld? or straight JB?

 

[chieffan]

Main things with JB Weld is to get both surfaces absolutely clean. Use denatured alcohol, etc to clean and then don't touch. Let it cure for a couple days just to be sure.

Regular JB. another thing to check see Post 104 - 106 here https://tractorfanatics.com/threads/life-in-central-texas-new-adventures-of-larrybl.457/page-6

Wasn't going to take it apart, but glad I did. It was a touch dirty inside. I used the JB weld, but not sure how much actually got into the part that needed to be reattached. I tried to take it out this morning, but it was pretty tight. Now to clean it all and put back together and test.

Good luck!

Question time. Which hose goes where? Not getting any gas flow.

 

[larrybl]

Hope this helps, I usually pressurize the tank to get gas out of the pump after removal to purge any air pockets. An old BP monitor works well.

 

[larrybl]

Little more help.

 

[Dpregs]

Got it hooked up right. When I shoot a little air in the tank gas pours out of carb hose barb. Just can't get it to suck gas on own.

 

[larrybl]

Did you get the 2 small springs installed correctly under the diaphragm?
Is the diaphragm flexible and not hard?
is the little vent hole clear, and the copper filter free?

 

[Dpregs]

I'll take it apart and double check. But I am not spending more money as I need it to run to sell and I have aftermarket fuel pump that works.

Well see unless I land the front bucket for it.

 

[Dpregs]

Took it apart again just now. I think I have everything in proper order. The copper filter moves freely. Everything has been carb cleaned and air blown. He are pics of it apart with order of gaskets.

 

[Dpregs]

Well, after a few tries at disassembling and reassembling with no luck I reverted to the aftermarket pump. Just doesn't want to pump. I am sure I need a full gasket replacement set, just don't want to spend the cash on it. Thank you guys again for help!

I looks to me like there's a break of cut it the diaphram at the bottom left of the circle? If it has a small hole or cut, it won't pump.
