Still have some tracing to do but fuel pump quit on the Demon today. Literally just happened bout two hours ago. It is a used Holley blue pump. Was on my uncles drag car. Worked fine he just built a bigger motor, therefore needed a different pump. I street drive the car and will eventually hit the track periodically. It is a 318, cam intake heads headers and carb is all that is not stock. Stock tank with eventual fuel cell maybe. 3/8' fuel line the whole way. I know this pump is over kill by far but plan to build something bigger and better in the next couple years.

I don't have any issues with the "noise" of this pump. Just curious to what everyone else is running in comparison.

Also, does anyone make an aftermarket sending unit for our stock tanks that will work with an aftermarket gauge? Seem to only be able to find 0-90ohm gauges.

Any help is appreciated!!
 
Did you run a return with that pump? if not, thats why you killed it. fuel gets hot and cavitates in those rotor pumps without a return.

that being said, as long as you have/run a return. the holley units are decent. i personally run an aeromotive with the build in return, which i love, but thats a big money pump for just a street car.

I'd go with another blue, or someone else will probably post a carter # for less $...which i hear are decent also.

here is your blue with a new regulator

Not true..i don't run a return line on my Holley black pump no issues in 6 plus seasons of racing..
 
To be honest where is the return line on these cars? I know two lines come off the tank but there is only one line on the carb or anywhere on the motor. My uncle had this pump on his 68 Dart drag car for 7 years. Then prior to that he ran another blue pump on the street non stop with no return line. I am not trying to sound like I am a jerk because I am not and all info is welcomed. Just trying to learn more and more bout these cars overall.

Why don't you guys go call holley and ask if those pumps are recommended for a dead end system on a STREET car, and i'll go ahead and unsubscribe from this thread, as i clearly have no idea what i'm talking about. ;) enjoy

I bought a HO mechanical pump from Jegs, 15 years ago. It supports my 430hp 360 no problem, with a 3/8 line, and no return.
Not what you asked, I know, but I like the KISS rule.

Very helpful. Reason I did the electric also is I spaced off installing the part for the mechanical pump when i assembled it...oops! Wont happen again. I wasn't going to tear the front back off to out it on either.

I did read your link you attached. It does say to run a return. No need to unsubscribe as your info is accurate. Just some people do things differently and have good luck or no issues.


Turns out my inline fuse blew. I didn't try to tinker on the side of the highway this morning. Kept that for the garage where some bozo won't hit me while staring at his/her cellphone. I appreciate the help. I will be tearing into it to see why it blew. This winter I hope to swap to a fuel cell and replumb all the hardline and wiring. There is always a better way to do something after you have done it wrong.

that wasn't directed at you bud, just my reaction to a typical one sentence warrior jumping in with an apples to oranges comparison, that completely steers someone in the wrong direction. far too often people jump in to just harp on someone else's post, without providing any realistic or good info. glad you found a fuse is your issue. No matter what someone tells you, the fuel gets hotter in a dead head system, and the fuel pump works harder in a dead head system. thats a fact.period. adding a return will cut down on both of those things, despite the fact that someone with a pump that runs for minutes at a time..has had one working for years.

let me see if i remember JR High math class...

heat + electric =bad
hard working pump + cavitation = less longevity

return line = more longevity.

more longevity = good

haha :cheers: cheers mate

Add less noise to that list of positives. If you have the bypass pressure closer to the required line pressure you need the pump is much happier and quieter.

Hey no one said you didn't know what you were talking about,but then again no one said you did know what your talking about either...i've run all my cars WITHOUT a return line and NEVER fried a pump as you say it without one,,
 
Lemme see, you're not interested in taking the timing cover off to put in an eccentric, but you are wiling to keep towing the car home? and spending time diagnosing and running a return-line. Did I miss something?
And as to the fuel-cell; whats your thinking on that?Just asking!lol

I have been driving the car with this setup for over a month now. It has a few hundred miles on it. No issues till now. As I said it was just the inline fuse that blew. Replaced and drove the wheels off it yesterday and still fine. Eventually it will have more motor. Haven't decided BB/SB. Leaning more to BB. Fuel cell purpose is to be more track friendly for tech inspections and to have the rear sump setup. The tow was free and it happens. It could happen with a mechanical pump also. I know with this pump I will have plenty of fuel supply for a larger setup. Not to mention the pump was free and is working fine. Running a return line will not take that long to run if I want to do it. It is recommended but I know it is not a must have. This may bother some people but we all do things different and go to greater detail than others. I posted this looking for info on replacement pumps. To see what other people were running. Yes, as most threads do it lead to other details. You gave your input on a mechanical from Jegs and I appreciate it.
