Repeatedly blown fuel pump?

[ilvracn]

all those little pumps like that mr gasket, and edelbrock are junk. find a wallbro, or get a holley red pump # 12-801-1. takes up more room and more expensive, but a much better pump. this pump runs 7psi, if the carb wants to overflow, you might have to get a regulator. but it should be fine, most needle and seats will take 7 psi with no problem.

Installed a Carter M3955 fuel pump but had to drill out mounting flange holes for the larger bolts. Much better pump than the Carter M4548 but was a very tight fit...less than 1/4" clearance between bottom of pump and engine. Now have float level control. The M4548 pressure was over the top due to poor quality control. Next project is the fuel tank level sending unit. Only ones available fail due to ethanol corrosion on the ultra-low-quality potentiometer. Marvel Mystery oil extends the life but failure is inevitable along with suction filter disintegration. That's what you get for trading off American Made for all things made in China. No nation is sovereign when it depends on foreign made for its sustenance. Tried to tell others what a mistake it was...but the profit margin dominated the market to our never-ending woe.

uh... those have been failing since they were new from GM regardless of the gas. no reason to make stuff up.

The business community sold out this country's domestic production for personal profit...don't have to make 'it' up. Lack of quality control and supply chain disruption are now facts of life.
