Is the factory fuel pump adequate to handle dual 40 IDFs on an 1835 or do I need to replace it? Do I need pressure regulators and all that stuff or am I OK with the standard pump and a T piece?

Standard fuel pump should be ok but yule have to put a fuel pressure gauge on it and check,spose to be 3 psi,i think your spose to use extra gaskets to get the pressure down,OR SO IVE HEARD.馃槈

Hey Barry, yep what? Adequate or need a regulator or both?

Yep - Luggy did a good post
Standard pump is adequate. A regulator is good.
"I" have been told IDF's like 1 1/2 lbs pressure and DRLA's can handle 3 lbs

Standard pump is fine, as you have a standard cam and heads. With a standard pump you don't need a regulator.

Like Craig said, it will feed your engine.
If you move up, you will need to go a to an electric pump. The "Facet" type is very popular, but needs a regulator - usually a very cheap taiwan-made chrome jobby for about the same price.
When you reach this level, buy a "rotary" pump - this is usually a Carter (a brand that is well known to us old-timers,) and is self-regulated (and has a filter included!) and, while still needing a block-off to sit where the original pump did, will feed any carbs you find until you reach the highly-addictive sub-12 set at the drags...
