Anyone make a 3/8" Mechanical fuel pump ?

If not,is there any tricks/mods to make it 3/8" ?

Seems like having a 3/8" line at least from the tank coming in couldnt hurt.

Thanks.

Yes, but will it help? I have never heard of any slant six suffering from fuel starvation with the stock lines. If you truly need more, you could run an electric fuel pump and the fuel hose diameter of your choice.

Yeah, I'm echoing Reed's question: Why are you running 3/8" fuel lines? If you're bound and determined, you can put together a fuel pump with 3/8" fittings, but it will be very costly to do so.

5/16" line is good up to at least 13 sec 1/4 miles. Stock pump is good to at 14-15 sec 1/4 miles depending on car wt and HP.
