Holley's Hydramat is now shipping - fuel starve solution?

Tractionless

For the price a relay, switch & battery harness should be included rather than piggybacking the Oe circuit. Doesn’t seem safe nor reliable especially for a street car.

Seems like you have lots of concerns and are talking your self out of Z1 kit. You should get phunk's kit as it is top notch. Those of us that have the Z1 kit have not experience any issues or at least I have not heard of any.

Yes I do, one of which being throwing part$ at an issue which might not be the fix.

I've also yet to hear from anyone with the Z1 kit that is using it on a street car running the auxiliary pump 100% of the time.

Sputtered to Stop......Now Runs Fine.

I drive mine as a sometimes daily driver. I'm not sure what the issue is other than fuel economy which I have never been concerned with, because it is a sportscar lol. What part of not being a real fix are you speaking of. There isn't anyone in this thread that has said their issue with fuel starvation was not eliminated with the kit. You are in the track section so maybe people who don't track aren't committing because they have found a fix and moved on.

I use my Z has a DD in the summer. With phunk's kit. Both pumps have to run all the time. No issues with the pumps.

Isn't that what they are designed to do run all the time regardless if you have one or two! Really the only kit I have heard issues with is the AAM twin pump system.

Yeah, both pumps have to run.

I read the thread on the AAM kit.

Did you happen to read the thread I linked of my issue? I’m not sure that it’s fuel starvation to begin with. That’s just what most members default to when the engine quits on the Z.

Car sputtered to a stop 1500’ after a 500’ right turn on the street which I took moderately at best and with 7 gal. in the tank. Suitcase in the back didn’t even shift. There’s more details in the actual thread.

I came proactively seeking starvation solutions one of which is the be all end all; however, IMO overkill for a street only setup and the other while no failures in the track cars it was meant for leaves ends untied for the street.

I did read your thread and I apologize if I was being harsh as I was not totally grasping your situation. I get it, you don't want to spend more money than you need to resolve your issue. From all the threads I have read on this issue regardless of track or street use only it seems there is a wide range between those that have issues and those that don't. I never experienced fuel starvation before hitting the track, even after boosting. Phunk kit was the first to successfully and reliably deal with the issue then came along the hydromats. For now these are the only two good options and one is more expensive than the others and deals with the issue you brought up and I got educated on and so you just got to decide which one is best for the money or live with the issue. Many street only folks have though it was worth buying the rrp system. I just decided to go a different route because of the build I have at the time I was looking to resolve my issue.

Thanks and no worries; I didn't feel you were being harsh.

I've decided against the pre-packaged starvation kits at the moment.

Instead I'm replacing the entire OE fuel pump assembly with a new one due to the sound of my fuel pump motor prime changing during the issue. I have a feeling the fuel pump motor is on its way out.

I'm currently debating using a Hydramat in lieu of the OE pickup sock but trying to find out the O.D. of the OE pump inlet as Holley only offers 11mm for such a configuration.

I apologize in advance because I know this has got to sound rude over the internet: But you do realize you can purchase Hydramats and fuel pumps just about anywhere right?!
