Holley Blue pumps and regulators?

Quote:

---

Ran 2 Holley blue pumps in series from 1988-2006. Same pumps and regulator never an issue. Car ran 10.80-10.90 from 1988-2000. Upgraded the engine and got the car down to 10 teens w/the same set up. Only leak I ever had in my fuel system was the big Fram fuel filter.

Why would you run 2 pumps in series and not parallel

I have REALLY hurt some guys feelings about their fuel regulators on my flow bench...........LOL!!.....Those "cheap" Holley regulators are the most repeatable and consistent regulator you can buy. The only drawback they have is the inner flow path diameter. But it requires BIG power to need more fuel than they can deliver and they are more than enough reg for 99% of guys

THIRTY YEARS AGO, the first 500" P/S cars were in the 7's, right? Holley Blue pumps and those cheap dead head regulators were the real deal.

So I cannot help but when a guy tells me that his motor NEEDS that $500 billet cement mixer pump and $200 regulator on his 9.80/135 mph car, "Cause it was too lean with the Holley stuff". YEPPERS, just had a Mopar racer tell me that a few weeks ago when I asked about his recent fuel system "upgrade". Oh, and he's really puzzled how there isn't any gain on the time slip...

This is a picture of one of Bob Glidden's Clevelands from about 1979-80. Pro Stock cars were going mid 8's at that time. Note the fuel system in the picture. Check out the water pump drive too. Pretty trick stuff.

LOL.. notice ALL of the RUBBER fuel hose.. I guess that
was before the 6" rule started

They made it work cos that`s all they had till "Bogus Junk" (BG)came along trying to up things a bit w/some success..............key word "some" success. If the blues were that bad azz how come pro stock doesn`t run em today............. Regulators yes pumps no way in hell they`ll work. I ran the Aeromotive hot rod pump on my car and it fell on it`s face and some of you agreed watching my 9.98 video..........maybe a bad pump don`t know or care since now I`m solidly in the 9`s and wasn`t before.

Come on, don't you think the fuel demands of TODAY'S 500" motor (1200 HP?) are a wee bit different that those in the 80's??

I'm saying that if those "junk" blue parts supported 7.80's @ 170+ MPH, then many of you 9-10 second guys buy the "trick" stuff because other guys and the marketing firms tell you to.

Again, my car fell on it`s face past the 1/8th w/a black Holley and the Aeromotive.............installed the 300 Magnafuel and had to re-tune the carb and went solid 9`s. And my car`s not that bad azz............

---

Ummmm, if you "had to retune the carb", how do you KNOW the pump/reg was causing your problems?

I once tried a billet cement mixer pump and high $$ reg on a low 10 second combo, replacing JUST the 10 year old Blue pump and reg. Adjusted the PSI to be the same, and ran it. Weather station was identical to the weekend before and said I should go 10.30's based on my data. (With the old Holley stuff).

Guess what??? 10.30's at the same speed with the new (thankfully borrowed) high $$ "junk".

It LOOKED trick though...

---

Gotta agree with ya. My old 9.80's car( 3350 weight) ran a Holley black and Holley large port regulator for years. Ultra consistent car, saw about 7500 at the stripe every pass.
I caved in to peer pressure and went hog wild witha return style way bigger pump/ lines,etc, etc..... And saw zero difference after throwing a grand at a nonexistent problem.
My new car is much slower, but I run a pump similar to a black on it through the stock tank sock, 5/16 line and small Holley regulator. It pulls hard on the back half
of the track for what it is, zero nosing over. I have no concerns it's leaning out.

I upped pressure and jetted it to the moon to get it to somewhat run to get the "volume" I needed and ran ok. New 300 pump re-tweek and string of 9`s no other changes BUT, I am a lucky hack so maybe that`s it...........

Small motor, small demands try that w/a stout big block and report back with us. Also do you have a wideband? Install one then you`ll see the fuel curve w/your own eyes and can verify not assume..........My car pulled like a beast, went to chassis dyno and was approaching dangerously lean 16.1 numbers..............

What do you mean, small motor small demands? Car ran the same numbers yours does and was 150 pounds heavier

My bad...........I was refering to the new 318 motor and the 5 1/16 line.............

Why would you run 2 pumps in series and not parallel

---

I was in college at the time and money was almost non-existent. Ran One pump but it would not keep up w/the motor so tried them in series and no more trouble. I could have ran them sep w/one to each bowl but more line, fittings etc and if one pump went bad(never did)one of the bowls would go empty.
This set up was basically a junk yard motor, heavy TRW pistons, 6 pk rods, 452 heads etc.
Simply was a cheap way of racing while finishing college.

---

You were only lacking a bit of volume so if you put
them in parallel you only have a Y and the 2 supply
lines.. no need to run 2 lines forward.. this has been
the way I've done it for years
