Dynoed 604 ft lbs at 4900 RPM and 606 HP at 5500 RPM

Thanks for any suggestions

And just for a quick summary of how I got here.

New GM Gen V/VI block with fuel pump mount.
Builder suggested I run 1/2" fuel lines and pick up from tank
Installed Baker fuel pump on block and found it doesn't fit with gen V sea pump/fuel pump combo. So he ran the OEM fuel pump for dyno break in/testing.

Apparently the OEM worked, but I'd feel better with larger hoses/fittings supplying fuel than a 1/4" NPT fuel pump.

I'd hate to damage a built engine over a $250 fuel pump.

if the pump boss has the room,,you could drill and tap it to a 3/8 npt.

I wonder if anyone has done that before?

Clearly the easiest route would be to use the KE upgrade fuel pump. It just stinks that there were a number of members that felt it didn't work for them. I'd hate to waste the $$ for it and not work, when I could put it towards something that does.

Anyone ever add an electric fuel pump after the mechanical? It would be similar to what merc does, right?

Don't beat me up too bad, just thinking out loud.

FYI: The spring inside the mech fuel pump determines max press output. Less throw on the lever will only decrease the volume per stroke.

However, if you're in the unfortunate position of being able to burn fuel faster than you can pump it, increasing lever throw will increase flow and press and decreasing lever throw will reduce flow and drop press. This is due to supply vs demand.

Its a good thing to have significantly more pump flow capability than needed. You want the spring to determine max fuel press not the volume being pumped.

You could just do away with the mechanical pump and install a nice electric (Weldon) pump and have all of the fuel that you could possibly need.

That is an option.

Is there a good thread I can read of someone doing an electric fuel pump conversion? I'd like to see what's all involved and what I would need to buy.

Thanks

Thank you

I just got an E mail back from Baker. It said they do not have one available at this time.

So I sent another question asking if they ever produced one? I can at least be on the lookout for one.

I've done a lot of reading about this and never saw the mention of a sea pump mounted Baker fuel pump. I would love to be wrong about this.

^^^If they did make a short arm, which looks like they could easily modify their existing design, I would buy 2 of them today. I've got a couple friends who are looking to ditch the Merc pumps, so that is 4 more.
