My 51 has a 54 235 in it, while trying to get her going I noticed the fuel hose from the pump to the carb was showing its age, so I pulled it off to get a measurement. When I got back from the parts store I discovered the gas was running straight thru from the tank. Is this normal or a sign of a bad pump? This is a plain pump, no vacuum port. Also, with the engine running, the fuel just trickles into the filter at the carb, making me wonder if the pump is weak. I wish I had paid more attention to what it did I parked it.

Doing the fuel pump volume/vacuum/pressure test that I've been recommending for years is the right way to check a pump, but to the best of my knowledge, nobody has ever bothered to listen to me on that one!

Typically, metal tube is used | | | | | Joined: Mar 2005 Posts: 209 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 209 | It came with the hose. I plan to replace it with metal when I get the bugs worked out. | | | | | Joined: Jan 2010 Posts: 4,263 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 4,263 | Sounds good
There use to be a video on this site that shows a glass filter.
Fuel just trickles in.
Search LonnieC “fuel filter “. It might show up
