... whats the best way to hook up a diaphram fuel pump to a 5 horse briggs should i use the crank case breather on the valve cover? if so do they sell valve covers that already have the fitting on them for the vacum hose? let me know thanks! austin,

nothing?

dont use the crankcase breather, you can drill and tap the side cover, ( in the right spot) and use a small fitting available at a hardware store and then the line,

Does your sidecover look EXACTLY like this?

if so, on the left side theres filler cap, and directly above that a flat on the top part
that is flat, and doesnt have a cap, you can drill and doit there,

A picture would be nice, I dont have a better one handy, I could always photoshop
instructions on it for you, its not hard

it is much much better to pulse a fuel pump from the intake.

from the intake? how? its gotta blow and suck air every engine ive seen they used the vacum on the bottom end of the engine i think thats the strongest vacum on the engine.

most common is on the intakes

Wow. I do not know how that one slipped my mind, Maybe Ill quit tapping cases, Both work well thou

I have done them both ways. On tecumsehs I removed the governor shaft and threaded a pipe nipple into the hole and used that to run the fuel pump. On a briggs 8hp, I tapped a hole in the top of the intake manifold and threaded in a fitting. Both work fine. I think briggs governor holes are too close to the oil level and would bubble oil into the pulse line.
