Hi

 

After rebuilding my twin carbs and still they were leaking fuel, I'm changing them for a single Weber downdraft.

I bought a intake manifold from a 4K starlet, but I'll still use my exaust manifold (4-2-1 manifold from the KE35)

I have a Weber 32 DGR (aparently like DGV, with manual choke). This one was mounted on a Suzuki, and luckily I bought it already with the suzuki adaptor plate (it's the same for K engine, I already tried it and if fits perfectly).

 

Now, anyone here knows what is the fuel pressure from the 4K pumps? Can I use the stock pump with the weber or do I need a regulator (or new pump and regulator)?

I'm afraid that the 4K mechanical fuel pump might have too much pressure and could leave the carb leaking. Anyone can help on this?

You'll be right running it with the mechanical pump.

 

Everyone else does, never had any issue's

 

Where were your old carbs leaking?

Hi

 

Thanks for the help. I'll keep the mechanical pump.

 

My old carbs were leaking from the throtle pump.

Even after changing gaskets and rubbers they were leaking. And they were a pain in the ass to sync correctly.

But I'll keep them in storage anyway.

If you are keen, you can pick up a filter king pressure regulator, though unlikely the fuel pump is over pressurising.

 

This functions as a pressure regulator and filter, and looks old school.

Good seller, and has been continually listing these for years. No need to get into a bidding war as they will list another when this finishes.

Just to add that my Weber DGR doesn't have a return fuel line (neither the previous KE35 carbs).

I'll try them. First need to clean them up while theya re not mounted, and I need do make new gaskets for intake and the carb base.

 

Thanks for everything.
