Holley Sniper Fuel system?

[Malicious]

Hi All,

Looking at a Holley Sniper and wondering what everyone did for a fuel system for it.

Has anyone used the master kit? Can the fuel pump just be added to the fuel line out of the standard fuel sender?

Has anyone added in an in-tank fuel pump to the standard sender, but cutting the pick up short and attaching an in-tank pump with sock - like a walbro - ala modern fuel pick ups?

I know you can pick up a new tank with pump etc, but my pump is new and I don't see the need to throw big money at a set up that seams easy and logical to adapt to the existing system.

Love some feed back!

Cheers!

Follow Andy F. on Moparts.com. Should tell you everything you need to know. I hope to have one also if I get some time.

I have installed 2 systems. And used the master kits. On the first car the GTX everything is mounted above the rear axle. Pre-filter,pump,post filter. But on the Roadrunner I had more time to be creative and installed it on the passenger side frame rail. Or you can go with an in tank setup. Probably less noisy if its in the tank. But do make sure you use ALL fuel injection hose. Dont do like I did and make a mistake of leaving one old school hose in. It busted fairly quick and gas was pumped everywhere..

Where did you mount the water temp sensor? Jus noticed the instructions mentioned it had to be in the intake or cylinder head, not pump housing? Thinking now, without the car in front of me, I can't think of an acceptable port.

I installed it in the water pump housing.. didnt have too many other options. But before you do you need to get an adapter from your parts store that will accept that chevy style temp sender and then be able to thread into the water pump housing. If im not mistaken its 3/4 NPT but the inside is whatever size that chevy style sender is.

From their instructions, sound right?

• 3/8” NPT Threads – Adapters to 1⁄2” NPT areavailable

Need to work out if I go ahead now (on sale) or later, but I think I'll look at running a Walbro 445lph in tank pump off of the standard sender for this. keep the pump cooler and less noise.

You talk about temp sensor not on pump housing but if you have a BB or Hemi you only have the pump housing as a place to get water temp.. I have a Fitech on a hemi and I bought a 1" adapter with 2 threaded holes that goes on the thermostat housing to give me a place to put the temp. sensor.

I put a Super Sniper on the 512 in my '65 Coronet. Fairly simple install. Now I'm adding the Hyperspark distributor and ignition box. I did an article for Car Craft on the install and I'm working on a second article. I'll attach a couple of pictures.

So you've put the temp sensor in a bolt in bung before the thermostat? is that better than putting it in the pump housing?

What made you choose the aeromotive drop in fuel pump set up? I was thinking a Walbro 455lph inline with a shortened pick up on the standard fuel sender would be sufficient. the return line was something I was mulling over tho. I was thinking potentially bulk head connector int eh stock fuel sender as well. I'm sure you had a reason, which is why I'm asking, not to be an arse!

I've actually found your thread on Moparts, just haven't had time to read through it yet!

Do share if you feel so inclined....would be nice to see how this is done.

The pump housing doesn't have a 3/8 opening for the temp. sensor and to plumb it correctly might not give a true reading. There is not enough meat on the housing to open up to the needed 3/8 pipe thread. I believe the housing is a 1/8 opening.

 

[Don Frelier]

When I installed MSD atomic I removed the pipe plug from the passenger side of the pump housing. I think it is a 3/8" pipe thread. You can see it in Andy's picture. So I have a digital readout and the original gauge, it's surprising how accurate the 50+ year old gauge is!

 

[tonysrt]

I have a mechanical gauge in that 3/8 opening. I wanted to keep it so I can always see temp.. That's why I added that 1" adapter to pick up the extra opening for the F.I. Temp. sender

Here you go. I was looking at this specifically as they were on sale, but I couldn't get it to time up with the funds, so I've let it slip and will get back to it later. Still dead keen on making this happen as the cold starts are killing me at the moment.

What made you decide to go with the Holey Hyperspark vs the Holley Dualsync?

What made you decide to go with the Holey Hyperspark vs the Holley Dualsync?

The Hyperspark distributor is designed to work with the Sniper. The Dual Sync is a more complex distributor which is bigger and more expensive. The Dual Sync is required when using port injection. The Hyperspark is less expensive since it is smaller and less complicated. It is all you need with the Sniper. If you have a Sniper then save the $100 and buy the Hyperspark. If you have port injection and want to control individual cylinder timing then you need the more expensive Dual Sync.

I have the Terminator (to be installed) and ordered the 203 which is what they (sales) recommended a few days ago...I didnt learn about the Hyperspark until afterwards...like the thought of a smaller dizz as I don't really care to clearence my heads...
I knew it was a complicated distributor but didnt really want to use a CD box.
