I picked up an R4781-6. I had some 50cc pump housings. The primary started weeping. Turns out, the fuel bowl pump housing screw holes aren’t deep enough. I added an .025” washer, and all is well.

I've converted many 4780 and 4781 with different dash numbers to 30 CC pumps and they ran way better on the street and at the track (quicker 60 ft. times ) than with the 50 CC pumps

Just about everything I have bought from the Holley Conglomerate has been complete $hit for the last couple years. I am done spending money with that organization. I put a post over on general about it the other week...but no one said anything...they're too busy jerking the company off over the Moparty. Here's a clip of that post:

- Frostbite 'direct fit' radiator that needs mounting holes redrilled because they're in the wrong spot
- Frostbite electric water pump that needed rewired because the fuse block they put on the power circuit was bad
- Hooker Headers with warped and mis-drilled flanges (right out of the box). Bought the same part number that was put on the car in 1984...tubes aren't even anywhere close to being in the same location either.
- Holley carb needle/seats that are bad right out of the package.
- Racepak software that needed debugged right out of the box after installation (Datalink gave error message every time you tried to open it after installing it on the computer)
- MSD distributor pickup that the magnet disintegrated on while I was taking it out of the package.

And I would like to add that since I made that post, my Racepak does absolutely nothing. I cannot get live telemetry, it won't record, it doesn't even show me voltage when I plug into the Datalink program, though the lights are lit on the Racepak and AF-1 Sensors.

I purchase hundreds to thousands of race parts each week. Yes, the quality just continues to decline with everyone not just Holley. More and more of the Mom and Pop racing businesses along with larger racing businesses keep getting purchased up by these investment firm companies. They let go out the true die hard racer personal and tear the companies to shreds and quality and knowledge goes right out the windows.

I added $1600 worth of sensors to my RacePak, last year, and it hasn't worked since...

But yet people keep buying there products.

This is where frustration on a message board does nothing. The people have the power to make a product go away or change for the better via by the wallet.

Never happen but folks need to band together and stop buying products from these companies till things change or they can go broke. But considering how the future seems to be on our fun stuff they may just not care and will ride it out till the end.

Either way, were the ones who take the hit.

People still buy the stuff because the products are promoted, or because the older products performed as advertised.
Outing the current junk is the first line of defense, and I for one appreciate that.
Damn few items are usable out of the box nowadays, it seems.
Wouldn't surprise me if someone at these vendors and/or holding companies has calculated profit/loss for stuff they know is at least problematic, if not outright junk.
That said, I've also seen parts installations that were either problem-causing, or a misuse of the item.

In my case, the water pump, and radiator were bought a couple years ago, the headers about a year and half, and the Racepak around the same time. I didn't install the parts until the last couple months as I was finishing the car. I can assure you that I am done buying their garbage. The next car will have a Daytona Sensors logger and ignition.

Just to clear up what I wrote a little bit. I was not meaning folks should not voice there issues with there products but for any chance of change or getting there attention it must go past a message board.

But see, they got the hook set with events like moparty. The LS deal and others they put on, ect..... Keep people distracted and they will keep buying there junk.

Id rather go slower and have more fun and less headaches even if it means being a bit old school on the parts used.

Yep, the private equity firms are destroying the car parts business. They are executing the classic PE move where they buy small family run companies and then gut them to boost profits before flipping them to someone who isn't paying attention. The whole thing collapses within a few years but the PE guys get a bonus. The employees get the shaft, the customers get the shaft and the company holding the bag at the end gets screwed. Unfortunately, people keep falling for this trick year after year. I have friends who work in the PE business and they make big money screwing others out of their jobs.

Doug Cook from Motion RaceWorks is constantly hammering the PE owned companies for all of the above reasons. Motion is an interesting company that had trouble sourcing parts in the beginning then just decided to start making their own stuff in house. They don't do a ton for Mopar's but the product line and quality of it all is very nice. They are now Motion Raceworks, TBM Brakes, and Rife Sensors and manufacture parts in Iowa and Florida.

^^^ Yup, plus the talent either leaves or is eliminated.
So we get Don't Care, Don't Know, and Don't Know How To Fix It...

Hey, I've talked to that guy. He must move around a lot because almost every place I call there he is.

Yeah over the last decade I've gotten to know "the last guy" at Crane and "the last guy" at Hilborn and the last guy at a few other places. They all tell the same story and it is grim.

in my working career as a machinist/shift supervisor, my company was bought by several PE outfits, and each time, the result was worse than the time before...........
the companies gutted the shop and products we produced, plus didn't invest in any equipment upgrades or maintenance, thus, it was a race to the bottom.
after i retired, it got even worse, as if that could possibly be contemplated.
i kept in touch with a few of my coworkers, and it seems that a serious company bought the remains of what was left a couple of years ago, and this outfit seems genuinely interested in growing the remains !
it has invested in some serious equipment upgrades and method improvements, and the products produced now are a vast improvement over what was available in years past !
to say the workers are happy about this is an understatement...............
so there is hope out there, but it takes a ton of effort to find it.

I work at Holley here in Bowling Green. It’s definitely not the place it used to be.

Just to add, that list number is kinda old, so quality has been steadily slipping. I had to return two main bodies that weren’t machined properly. HOWEVER. I called K&R Performance and got who I believe to be the owner. 2 rings, Friday afternoon. Knew exactly what I was talking about in seconds. If you need a delay box, I highly recommend them.

I also highly recommend K&R for their delay box . Yes Kevin is the man to talk to . Gary

Well, maybe the one, small silver lining to all this is that maybe, just maybe, the smaller shops and guys will start getting more of the attention that they deserve as the big guys continue to screw up and alienate their customers.
