ok well i do know alot about enignes but me and my friend are builing our first and i need to know how to get the fuel to my carb hence im going from 305 TPI engine to a 357 CARBed. ne ways i know the EFI fuel pump sends too much pressure for the carb and i know there are regulators out there. but how is the whole thing setup can someone please tell me how to get the fuel to my carb without going into my fuel tank?

 

Look at this post from last week. https://www.thirdgen.org/techbb2/sho...hreadid=199078

Let us know if you have any other questions. Only difference is your pump will put out up to 50 psi, whereas TBI is on the order of 9-10 psi. The issues and resolution are identical, however.

 

I unplugged the connector from the fuel pump relay on the firewall, bolted a used mechanical fuel pump to the block, redid the pipes and that was it. I haven't used a return line. Just blocked it off.
The mechanical pump pulls through the electric one. Dead cheap and quick. Works well.

You need a mallory #4309 regulator. I have one and a whole carb setup 4 sale in the classifieds.

Summit and Jegs also carry them.

 

I have posted this in other threads too but i will do it here too. I hav a TBI pump and the 4309 regulator and my fuel pressure wont stay set. I have taken the regulator apart to check it and its fine. I can set it at 5psi, sometimes it will go down to 0-2, other times it will go up so high it blows the needle and seat apart, I can hear the float bouncing up and down.

 

Im using a Barry Grant FPR on mine. I swapped from a V6 to V8.

 

I haven't had a problem with a 4309. Are you sure you have it hooked up right?
