Lombardo j Robert says:

Wow almost 3 grand to replace a carb that’s worked for over 150,000 miles.

Hi, Iwant to ride the Holly bbd EFI SNIPER in myJeep,Iask youhave to buy a atank and ignition. My Jeep has a HEI ignition and it has a aHolly gas pump. What it has is carburation problems with the BBDCarter.

Brian Palm says:

So there are 2 pressure regulators in this setup? One as part of the in tank module as described in the part description and also one on the efi itself…does that cause any issues? I thought one of the benefits of the Holley internal tank pump system(as described in the in tank pump spec (part #12-307) was that a return line wasn’t necessary because the return action happened inside the tank with that regulator…and if a return line isn’t necessary, would you just cap off the return side on the efi? Just wondering about effects of 2 regulators…

Steve Zickefoose says:

I have a 1983 that may need the stock MCU replaced, I'm in California will this kit pass california emission inspections

Rafael Torres says:

Will it work on suzuki samurai?

Kevin Beaudreau says:

Agree with the comments concerning the red-headed stepchild. the 87-90 YJs come with the same 4.2L engine, but the gas tank listed in this video doesn't fit (according to Holley when I spoke to them). So while the EFI system "should" work, we are stuck with the external fuel pump. Would love to see Holley put out some parts/videos for the YJ (we really need the help).

Also, what about the old computer and wiring harness? what of that can be removed?

Chris Drews says:

I am looking to put this on my 83 CJ7, I have stainless gas line from tank up frame to fuel pump, is it necessary to eliminate the gas line and run a new one?

john Doe says:

Will this work on 87-90 yj's with the 4.2?

Nioreh says:

I am thinking about getting this for a -75 AMC Pacer with a 258. Apart from my intake being a single barrel, is there anything else I should worry about?

herbiesnerd says:

I want to get this for my 1990 YJ but I have a few concerns.
1) Are you guys working on getting this CARB compliant for California?
2) I plan on keeping my Pulse Tube for CA smog. Do you guys have any instructions on disconnecting pins no longer needed for the MCU?

3) Do you have a cover plate so I can remove the mechanical fuel pump?

Do you carry a 20 gal tank and pickup as well?

Please include our ugly stepchild ‘87-‘90 YJ’s with Carburetors and smog crap.

Wes Senechal says:

Installed the Sniper EFI but my smog tubing is blocking the fuel inlet, which 90 degree fitting should i use in place of the one that came with the kit? Is it part number #98220berl?

Heather Ball says:

why wont this work for 87-89 258 yj's?

Phil Turpin says:

So what if I didnt want to change the fuel tank that has no internal fuel pump? Would I use an inline?

RCB 411 says:

I have a 68 c10 with 250 inline 6. Would this kit work for my setup or do you have a kit for the Chevy 250

Richard Castillo says:

This is cool, but retains all the exhaust pulse tubing and vacuum lines. I am very happy to get rid of all that rusted out junk….but now comes the smog test…..

Richard Castillo says:

Wow, wish this was available when I did mine…..Nice!

Oliver Silva says:

My Jeep came with 1 barrel, and 2 bolts, do i need to change my manifold intake?

Carter Stokoe says:

Will this setup work on a slant six? Ignition module and all? Not sure what a 4.0 firing order is
