The pump kits have the same Chinese parts that most new pump have. There is a chance of messing up the kit install into your old pump, if you have one. I don't know what pressure it takes for two carb bowls, this NAPA pump has 5 psi.. It's a local buy and easy to take back with no shipping, Free delivery if less than 5 mi from the store. It's Delphi and says "United States"
Reason for above comment/opinion:
The best you can do to make a choice now-a-days is to mitigate small headaches, factor in best bang, due diligence, return difficulty, warranty, reputation of seller, rebuilt vs new... as I did above. I buy from everywhere, not just NAPA.

I bought 3 when they were cheaper than now.

It is much appreciated! | | | | | Joined: Feb 2004 Posts: 29,771 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,771 | While having good fuel volume is important, running dual Rochesters on a 235 is WAY overcarbureted unless the engine is highly modified. Good luck!

He and Jon H (CarbKing) have for over a decade explained why and how a stock 235 will suffer from overcarburetion. For a stock 235 I suggest a stock intake manifold, a stock exhaust manifold and for the 1957 235 definitely a Carter YF3211S in good nick & adjustment. That Carter is a great improvement over the Rochester B or BC. As for a fuel pump, I have used an electric pump with great success since 1997...about the time fuel pumps in the USA stopped being produced. The pump I use is an AutoBest model F4027. It will output around 3 psi (which is just what you need) and my experience has been the pump lasts a long time. On Amazon currently you can buy one for less than $20 and it is made to handle ethanol-laced fuel. Good luck!

Install one and put the other under the seat along with a spare filter and hoses. This will save you a tow bill when the pump gives out. I'll spare you the story of changing one in the rain after a tow and a two mile walk to FLAPS each way.
