  View original topic: Electric fuel pump to stock
bustedBuggy Fri Apr 01, 2011 10:08 am

I'm pretty sure my fuel pump went out last night. The car just started slowing down and it died. Usually, the electric fuel pump makes a clicking sound when I turn it on. It didn't do that anymore.

I was wondering, can I replace the electric with a stock pump? My only conern is that I have a 1776 engine, and as I was looking through posts, I came across this quote:
"You really don't need an electric fuel pump for a stock motor."

My engine isn't stock. My carb is. Will a stock fuel pump work out OK?

The stock mechanical pump should be able to supply adequate fuel to a 1776. What you need to watch out for is not the size of the engine, but the type of carbs. If you 1776 has a stock carb in the center, it should be fine. If it's been converted to dual carbs, most dual carbs need a much lower fuel pressure than the mechanical pump puts out.

If you do have dual carbs, then you'd be best with another electric pump as you will need to add a fuel pressure regulator to the mechanical pump.

A stock fuel pump will work fine. I have a 2180 CC with dual Webers and I have never had a fuel pump problem.

Sounds great, I really appreciate the advice! Do I need to switch out the tubing as well, or just the pump itself?

I run a stock mechanical pump on my 2180 with dual 48 IDAs.... you'll be just fine with a 1776.

Doesn't that depend on his carb(s)? 48 IDAs use 3.0-3.5psi fuel pressure. On the otherhand most Solex and Kadrons use 1.5-2.0. For those the stock mechanical fuel pump would deliver too much pressure.

Just one carb, and its stock

You can shim it or add a regulator. All electric pumps require a regulator either internal or external.
