been reading this topic , with interest , would appreciate any information , does any one know , what make & part number electric fuel pumps when switch off ! eg , that would be used as a priming pump , allow fuel pull through , by the mechanical pump ? would have thought electric pump makers would have supplied that information with pump specs etc , seem to remember this cropping up in a thread some years back , was soo long ago , I cant really remember

thanks in advance for any input thoughts ....

What if there was a product that you could add that would not only supply fuel to the carb before the engine starts (for easier starting), but would also be able to feed a carbed or fuel injected engine up to 1000 hp (on gasoline) while still using an otherwise completely stock fuel system?

Yes, it really works. The only limitation is that you can't go full throttle continuously for more than one mile at a time. But if you are driving a street or drag race car, how often will you hold the gas pedal to the floor for more than a mile?

Hey, that looks like a great idea too. Thank you !

I had a few PMs asking about the check valve shown in the picture. It is an Earls item, P/N 251008ERL, I got it either at Jegs or Summit. The pump is a Carter #P4070, I used it because it did not require an additional regulator - the pumps are rated 5-7 psi. I used #8 AN fittings (1/2") to reduce any potential plumbing resistance. I tried to make mine as simple as possible but still be neat. You can surely save some money by going with some generic fittings. I can't remember if these were Russell or Earls. If you go with the AN fittings just mock everything up loosely then you have to put a slight twist in the assembly to get it snug. I located the bracket in the axle tunnel using locations that were already there so no need to drill extra holes. One hose come up from the gas tank and the other hose connects to the fuel line on the frame. Everything fit just fine even with the Dana 60. Years ago on this forum I had supplied a full list by part # but can no longer find it...

I would run a line on the inlet side from the electic pump to the line between the mechanical pump to the carb. with a check valve to prevent drain back from the mechanical pump
That way it will fill the carb. every time you use it instead of having to rely on the valves in the mechanical to be open to allow fuel to flow upwards to the carb.

thank you for the replies & pictures etc
