2Pcs Bulb Type Rubber Fuel Transfer Vacuum Fuel Line One Way Fuel Valve Fuel Pump Line Hose Hand Primer Gasoline Petrol Diesel Pump For Marine Boat 6mm 9001080A (5/16)

GOOD PRODUCT

I haven't used them yet, but they look as good as any that I've bought in the past. They appear to be sturdy and should work for priming my outboard motor with fuel from the tank. The delivery to me was very quick.

These work fine, but they do not return to shape as well as I would like them to. They are missing an internal bladder to force the bulb back into shape which would help with priming and flow through.

Received parts which worked well.

Made good

Bought two of these primer bulbs, one for a welder and one for a lawn mower. The unit on the welder, stored outside, failed within a month. So they aren’t UV resistant at all. The unit on the mower, stored inside, failed within three starts. The rubber is covered in cracks on the bulb and is also broken where the fittings connect to the bulb. Complete junk. Wouldn’t even recommend these if you just wanted to throw money away.

They don't stand up to the sun and they do appear to have "dry rot" as the summer comes to an end.

The inlet and outlet are made of aluminum. Seems to be better over all quality than other fuel pump bulbs I have owned.
