Originally posted by coneheadI just got mine from summit racing last week. It looks like a nice system but there are a couple of small issues. It doesn't include a fuel deliver system like the original Pro-Flo system did so you have to get their package, $483 at summit or make your own. Their is no baffle under the intake manifold to stop the oil from entering the PCV valve and the intake manifold gaskets that are included just cover between the intake manifold and the heads leaving the lifter area exposed. AMC used a metal pan gasket type that I think you have to use.
Several companies make fuel delivery systems, or you can piece together your own with a good high pressure pump inside the tank and a return line through the OE sending unit. Much safer then running a fuel sump under the hood!!
The intake manifold has provisions (boss's) to install the OE PCV baffle (off of a stock intake) to the underside of the EFI intake. And yes, you should use the OE style metal valley intake gasket91 XJ Cherokee Limited

Has anyone installed this thing in their FSJ? Curious about the height and if there are clearance issues. And of course curious about the install/performance!
Looks awesome and with timing control out of the box makes me second guess getting a Sniper and also getting Hyperspark. But am wondering about the height - saw some folks who had issues but they may have been in AMC cars. Just want to make sure I can close my hood.1984 GW

Me, I prefer to go the "unsafe" route instead of starving my high pressure fuel pump when I slosh gas away from the pickup at under 1/3 tank.1990 Grand Wagoneer with HD towing package -- everything works! (for now...)

I'll go out on a limb here...
He is simply stating the fact that any fuel sump mounted under the hood of an FSJ is not as safe as an in-tank pump.
These things crumple up like a beer car in an accident.
Obviously having a large container of fuel under the hood isn't as safe.Tony

Just because we make fuel sumps doesn't mean that is the best way to go. I do know that I would never put a plastic container of fuel and a high pressure fuel pump under the hood of my own car (no mater who makes the fuel sump)when it's more efficient and safer to have all the fuel and the high pressure fuel pump inside the fuel tank.91 XJ Cherokee Limited

I sure wouldn't even put a metal one after seeing first hand what happened with a ~35ish MPH crash did on mine recently.Tony

Howell EFI has recently released a carburetion to throttle…
I'm still looking at the best option too though, since at some point I'll want to delete the stock dizzy, the carb, possibly the EGR (if I can -- smog requirements??), and of course go with a better breathing intake and 4bbl-type set up and coil for increased power.
At some point I'll make an excel sheet listing all my needs, what each kit offers, and what else I'll need to piece together for a full-on EFI, intake, dizzy, coil, and fuel pump set up.Last edited by MysticRob; 04-01-2020, 01:35 PM.--Rob--

One point that nobody has mentioned yet: the intake manifold is a Victor Jr single-plane design which typically has an operating RPM range of 3500-8000 RPM. It's absolutely the wrong manifold for the 1500-5000 RPM range we need power in.
The same kit built on a Performer manifold pattern would be far more suitable. Sales volume would obviously be minimal, so it will never happen, but it would be far better for Jeep/truck use.
Better yet would be a manifold actually designed for use with EFI instead of a carburetor manifold with injector bungs scabbed in. You know, something like an OEM intake manifold - they look nothing like a carburetor manifold because they aren't designed around a carburetor-style throttle body. Consequently, they work a lot better at making power at real-world speeds.
Cost would be significant and sales would be zero, but it would be fun to build. And by "fun", I mean a gigantic pain in the hinder.
Not trying to rain on anyone's parade here - just want to make sure people know what they are looking at.'85 J20 Old Man Truck, bought @ 65K miles - not great, but better than walking.

.
correct. however, keep in mind this is now a "dry" intake,and thus air velocity thru the carb to maintain fuel shear and atomization and fuel suspension is no longer a factor. air velocitythru the carb is one of - but not the only-factors for a dual plane intake.
while intake runner design does indeed affect power band,i think this intake will be far more forgiving operating as a port injection unit.Originally posted by HankrodRistows right.................again,

It looks to me that it may have been ran with no oil in it causing the bearings to be wiped out and the thrust bearing has actually cut in to the crank about 1/8". So.... he
