    For A streetcar that's way too loud and ridiculous... I had one in my car even when I dragged race with open pipes and it was too loud and annoying...
    I still use it for my nitrous but I haven't used that either... But when I activate the nitrous I know it's running... There's no way in heck I would recommend one of those for someone's streetcar...

      When I swapped in the 5.9, I considered going with a Hughes cam snout extension so I could run a mechanical pump, but I was concerned about using it. Oh well, that's what makes this hobby fun!!

        In the Eighties I went through two HOLLEY Red's that developed a crack and started leaking through that cheap Zinc Pot-Metal housing in a year on my 1st street/strip car. At that time rod wasn't available to braze that crap because god knows I tried. Went to a CARTER 4594 with it's REAL STEEL HOUSING and I haven't looked back since, currently have them on two different car's and one even feeds a Dominator.

        Both of course are regulated but neither setup runs return lines and I've had to replace One once that just flat out pooped out after 20 years.

          If you decide on a holley pump, spring for the g-rotor version, (black?). Quieter, no vanes to stick. It is not real cheap, but you asked for "best".
          As far as a pump that will last.... ive got a 250 mallory g-rotor that i bought from a super shops (remember them?) warehouse sale (along with a coil and ignition box)in the late eighties.
          They were remans, and i heard that Mallory remans were hand repaired and much better quality than the new parts.
          All three are in use today. I think i paid under a hundred bucks for the three of them. The pump alone is now almost $600, if you can find one, and the box with the same number is now just a rebranded msd.
          I recently bought a trick flow pump (for a car that didnt need 250gph), BUT, if i wanted quiet and dependable, i would by a 140gph mallory gerotor.

              As is typical on this site when anyone asks for what is the "best" the answers that come back would make you want to rephrase the original question to whats the best on a tight budget because I have never once seen a remotely correct answer for the "best" of any part that gets asked on here.

              I'm willing to pay for a good one. And there were all price ranges suggested.

              "Best" is pretty subjective. A better title could have been "Suggestions for electric fuel pumps for carbureted warmed over street cars" or "What electric fuel pumps do folks like for a street car."

              I was frustrated last night and wanted to see if maybe there was a pump I hadn't heard of before.

              I read through a LOT of threads and feel like I learn something from each. Then there's the wit that makes me chuckle. And let's not forget @Kern Dog photos in the OMG thread :D FABO is awesome!!

                Facet jiggler. Pumps just fine, about 4 psi and will run forever. stock one in my 260,000 mile 82 B2000 was just changed out..35 GPH...? You ever gonna burn 35 gallons in an hour? Well, maybe in a 6mpg 360 Ram towing a boat..uphill. I had a Carter rotary (sounded like a dull snare drum that slowed to a very slow beating when under pressure) and only thing that killed it was me leaving the pump on with a empty tank, ran all night and burned out with no cooling fuel through it. Holley red/blue/black are all too loud for me. Mercedes had external "Walbro" style inline EFI electric fuel pumps for years and they were made quiet by isolating them from the frame by hanging them in a box off the rear of the tanks with rubber isolators and rubber fuel lines in and out. The bigger models used 2 in series! Grab the whole thing at a self serve yard and you'll even get the 10(!) micron filter if its off a K-Jetronic EFI.

                  Ok, I have to ask...do you still have the pump and do you want to sell it? I want a different fuel pump for the engine dyno.

                  Also, what ignition box and coil, and if you still have them do you want to sell them?

                  TIA

                    I've had great luck with Mallory 140 pumps. Not sure why they're so damn expensive these days though.

                      The mallory 250 is going in my bbc powered opel, and the mallory 690 box hyfire V, and promaster coil are both in my 62 savoy. I trust my 30 year old stuff much more than what is on the store shelves now, so im not really interested in selling them. Sorry sir.
                      As for the trickflow pump i bought for the savoy, im happy with it so far. It took the place of a 150gph paxton that worked good, except that it lost prime everytime it sat for a week.

                          Aeromotive are fantastic pumps. Again, u get what u pay for. Even the so called no name brands (Holley) look a likes work decent. The Carter’s are great too. It depends on ur hp goal. Kim

                          I am a huge NON-fan of in-tank pumps. In my experience they are NOTquiet, NOTan easy install, and NOT reliable.
                          The first time one failed on my fun little cheap driver, on the freeway, ON THANSGIVING, the tow and a new pump cost $800. (Or was it a thousand?)
                          The next time the replacement failed, it was as i pulled into my driveway. I could tell it was the pump again, because the noise it had been making for a month was gone. I threw the car away rather than fix it. (Literally gave it to a friend, who runs an auto repair shop). It hasnt run since.
                          My girlfriend got her truck back from some relatives she had loaned it to. They had disabled the truck, by destroying the in-tank fuel pumps circuitry(two tanks) to keep an Alzheimer patient from driving it.
                          If it ever runs again (doubtful) it will be because i replaced the fuel injection and in tank pumps with a carb and a pump bolted to the framerail.

                          Well it pretty easy to see you think In-tanks are junk lol.... In pure logic just look around you when driving. Chances are what is beside, in front, and behind you has an In-tank. I don't think the automotive industry would use it as their staple of fuel supply if there were the problems you described far and wide. But what do I know lol....

                          Well, i agree, the great majority of vehicles on the road use that style, and i did say "in my experience".
                          I was just trying to say that I would never build my hotrod that way.
                          (And i dont think the automotive industry gives a damn if it costs $1500 to replace a pump, once its out of warrantee.)

                          I think everyone can slice the pie how they want. But in my life it's an in-tank unless I am looking to make power that exceeds that capability. I have run a dual-in tank setup and had great results with that also...

                          Cheers,

                          I have had many vehicles with in tank fuel pumps only failed one.
                          I never let the fuel level get below a 1/4 of a tank so the fuel in the tank keeps the pump cool. Changing the fuel filter (if it has one ) per the book helps a bunch.

                            My 03 Silverado obviously has an in tank and that bad boy has failed me twice. Once at 5PM (my work garage was closed) so I had to call fleet to get a tow back to my shop where my car was, and then a second time right on the freewayofframp. I managed to run a red light to get the thing out of the intersection because I could feel it crapping out. Called the garage on that one and the guy came out and got under the truck and kicked the tank about 10 times as hard as he could. Told me to try it and the thing came back to life! He told me to drive it straight to the garage and he changed it out that day. Ford trucks had inline pumps on the framerail. Super easy to replace. Im not a fan of in-tanks myself but for a modern car that is very quiet, Its almost mandatory.

                            I bought an Edelbrock 1792 from another member. Got it installed and back on the road. But I pulled my radiator on Thursday and took in in to be flow tested. It wasn't cooling the 5.9 like it was the 273.

                            Here's a picture of the fuel pump. The muffler is not as close as it looks in the picture.
