Let me know what is your favorite fuel pump either manual or electric based on reliability and long lasting.
I have had several pumps and all of them ended up leaking fuel at some point.
I think that once it starts to leak there is not much to be done.
What do you think?

Davis six shooter, never let me down, and if it starts to leak you can get a full service kit. Had mine about 20 years still going strong and it's still not leaking
Dubro used to make a black fuel filler bulb for gasoline it was made of rubber and you squeezed one way up to fill then inverted it to empty, it never let my buddy down he's had that about 20 years as well. It can be used for gas or glow.
Slimline pro is also a good one but ive only had that setup for about 10 years.

My all time favourite is the Davis six shooter, it may not be the fastest but it always gets the job done.

Good luck

Slimline SL2000. I've had mine about 10 years. Went through the same issues over and over. Never had one problem since buying this one. I have a 1200mah 3s lipo running it

Slimline SL-2000.Have had mine over 15 years. Still going. I put a 3S Lipo on it and screw it on the bottle. Now I have had 3 batteries on the pump in its life.

I have had the gear driven pump: they wear out.

Six shooter: well that lasted one season.

I have a discuntinued K&S crank fuel pump that has started to leak just like other pumps do.
I just bought, from ebay, a discontinued metal pump unit (K&S1206).
Not cheap for $55.00 but all the components are CNC and it uses a plain
O-ring instead of the flat rubber gasket found in most hand pumps.
K&S sold its crank pumps with either plastic or CNC pump unit (core)
The cheap K&S crank pump with the plastic pump unit also uses a flat rubber gasket that can not be replaced once it starts to leak.
The plastic version was about $25.00 and the CNC version was about $75.00
It will be very intersting to find out how long it will take for the CNC unit before it starts to leak. I Hope it takes a long time.

My Slimline SL2000 is probably 15 years old and is the best fuel pump I've ever used and I've tried quite a few. I got mine back when the battery bases were still available.

I think I will try to source some extra o-rings when the CNC unit shows up.
I do have some O-rings at hand but to find the right size will be the question.
