Finally got the engine and parts back. Got the engine set in the boat this weekend.

I gutted the old fuel system and now have a earomotive and regulator to feed the engine and the Whipple. This of course was dynoed with the new engine and has already been set.

I have to mount and re-plumb these items in the engine bay. I'm going to mount the new pump on a stringer and mount the regulator on the front of the engine. Now I have "T" in lines for the injectors for the engine and and for the extra injectors on the Whipple. I also have to tie in a re-turn line back to the outlet side of the pump from the regulator.

Anyone got any pointers on this ??

Thanks,

Shawn

typically the return line goes tthru a cooler before dumping back into the inlet side of that pump. you can mount the reg. near the injector rail as to help pressure flucuation, but that pump is pretty good at maintaining it's setting. also check for a good location for your boost reference if using the aeromotive reg. as well.

hope this was a help, good luck

Appreciate the input. I will most like use the fuel cooler from the old Whipple setup for it then.

most importantly you should abandon the return back to the pump and return it to the tank if in any way possible. the pump will tend to cavitate, and vaporlock when hot if returned back to the pump. especially when idling for long periods. this may not show up for awhile untill the pump is already starting to fall apart on the inside and you are wondering why it didn't last as long as you thought it should.

Send it back to the tank !!!

i agree with this method , as this is how i set up most of my fuel systems. how ever there is a specific reason, of which i forget rite now , why aeromotive and whipple suggest to install. and i believe this gent. has a whipple kit.

otherwise i would suggest using a return style regulator, like a weldon, and indeed go back to the tank.
