🔧 High-Performance Five Oceans EPA One Way Valve Large Primer Fuel Bulb for 3/8” Hose FO-2877: A Reliable Solution for Efficient Fuel Transfer Review

I had to replace the entire fuel line so I took these, not the originals, for faster delivery. Some of the bad reviews made me suspicious but that's what I can get on the spot if it was bad. Works great for me, no problems.

From this I made an alloy vanity. The lamp itself looks more like plastic than rubber. It doesn't recover very well after compression. Poor self-priming. Not so big output volume compared to other similar ones. It works, but I will change it.

I installed this on my Yamaha 175 Grady White to replace another primer bulb that was too difficult to pump, especially in the winter. It is very soft and easy to inflate. No leaks or other defects. I've only been using it for a few months so it's too early to comment on durability.

Bad filler ball I'm not sure what application this would be good for, but it's not for boat engines. The vacuum pressure crushed the ball and restricted the fuel supply, causing the engine to stall. Unfortunately I didn't dress and review them as it was a project I wanted to do in the fall and didn't figure it out until it was too late to come back. Do not use on boat engines.

The primer lamp stopped working after 6 months. I use this bulb to fill golf cart batteries with distilled water through a single fill point. Only used 1-2 times a month. I even tried filling it with water and a suitable plastic tube so I could use it, but that didn't help. The lamp is broken inside. It wasn't expensive but it didn't last long so I can't recommend this product.

Done. Doesn't pump or fill at all. I put the old used bulb back on a new one which I replaced with a new one and it worked straight away. Don't buy this. I read the reviews before buying and they were ok. I noticed that one person said it didn't work out of the box, but I thought I'd give it a shot. I should have listened to him. Sometimes I think that people who write good reviews are paid by the company. At least Revain has a fair return policy and they refunded me for the 2 day shipping I…
