Im putting a mr.gasket 95a psi electric fuel pump on a 71 dart with a 440.which would be a better spot to mount the inner fender or by the gas tank?do you really need the other fuel fliter they recommend?how do you wire it up to?

electric fuel pumps are pusher and not suckers....put it near the gas tank

The pump should come with instructions, but these are the rules of thumbs I follow.

Mount the pump as close to the tank as possible. It should be located below the level of the tank pick up.

Wire it from the accessory circuit to an on/off switch (located where you can reach it in case of emergency while driving) to the pump.

Add the additional filter.

Install a pressure regulator depending on your induction setup

Well mr.gaskets #95p doesnt require a regulutor.there no room near the fuel tank.only room at the bottom of inner fender.unless send me pics of setup.has anyone mounted in the inner fender with no problems.if mounted where the tank is how are you suppose to wire it to the oil pressure switch if mounted clear by tank?

Mount it in between the right rear corner of the gas tank and the inner sub frame up I
I installed my Magnafuel Pro star 275 pump there on my 1971 duster, plenty of room there scope
You will need to reroute the pick up feed line to the pump and extend the line to the front, easy peasy whistling
AKA aside, it is worth mounting it back there and redoing those lines, maybe go with a 3/8 pick up and 3/8 lines to the pump and carb at the same time work up
Good luck, let us know what you do thumbs

There should be room near the rear of the gas tank. It depends on how big your exhaust is.

Why do you want to wire it to the oil switch?

According to the instructions it said wire to the oil pump switch.

These should be the installation instructions for your pump.

https://www.carid.com/images/mr-gasket/fuel-systems/pdf/95p-installation-instructions.pdf

If you read Step 1 where you mount the pump should be obvious.
Back by the tank.

Wiring it into the oil sender wire would be optional, not required.
The reason why it would be wired in would be so that if you lost oil pressure it would cut off the electric fuel pump stopping the engine.

Forget that. You should be paying attention faster than an idiot switch. Install a manual switch for if something else goes wrong.

What are the risks of not mounting it by the tank and only the added fliter behind tank?i have seen cars where they mounted pump to the inner fender.

You're working the pump harder and it will wear out sooner.

It will probably have a harder time delivering the fuel volume too.

Mount it in the back by the fuel tank like you're supposed to. twocents

Just because someone else did it wrong doesn't make it okay for you to do it wrong.

So you are in an accident and you are knocked out. Now when are you going to hunt for the manual off switch? Mean while the fuel pumps are running full bore. Get a good oil pressure activated switch and wire it in the circuit. Good insurance in more ways than one!

I have my pumps wired to switches that have a momentary side, center off, on. I have the momentary side hooked up to by-pass the oil switch so that I can fill the carbs before I try to start the car. After I have the bowls filled I switch them to the on position and let the oil switch take care of it from there. Very simple. Also use a relay to the pump. Especially if you have the battery located in the trunk.

Oh by the way I also wired my MSD hot wire to the oil switch. Oil pressure dies and it kills my ignition.

I ran the Holley red pump for many years that needs no regulator as its preset to about 6 to 7 psi. I also found it was hard to actually mount it lower then the stock tank pick-up. So I mounted it right in front of the gas tank close to the sending unit outlet. I also always put a small amount of eng oil in any new Holley pump when I used them so it would not spin dry at all. I have ran the red pump like that for 21 years in my sons Dart and ran one in my 63 for 6 years until I went to the black pump. The pump primed with no problem and has never given me any problem at all. I would not say my pump is lower then my tank pick-up but its real close to the sending unit outlet that's in the front of my stock tanks and has worked fine all these years set up like that. I can say my pump sits even with the stock tanks sending unit outlet fuel tube. Its really tuff to try and find a good place to mount a fuel pump lower then the stock tank pickup since the sending unit pick up should be on the bottom of the tank. So I mounted mine where it is and it has always worked fine. I have never run a fuel cell on my cars as I have always had stock gas tanks and I always have run Holley electric fuel pumps because they have worked great for me. I also agree that wireing you electric pump through the oil pressure switch is a good idea. Ron

Same way I did my setup to kill the MSD. Used oil pressure switch to a relay that is also to a light on my dash. If you are racing and do not have you face looking at the gauges or see the red light? Death will result. I have mine setup to turn light on and kill engine. Boss told me about killing pump is not really a good idea with carbs. I have 2 two 750 double pumpers on my engine and I can guarantee you that thing will run for awhile if you just killed pump only. I also have rocker switches for my pumps to kill them. BUT things do happen when racing or running hard and you may not see it until major issues happens to be able to flip them off.

Do it right or don't do it at all. The Mr. Gasket instructions are quite specific. http://documents.holley.com/mr_gasket_electric_fuel_pumps_instructions_95p_105p_130p_2015.pdf

It's a GRAVITY FEED pump meaning it isn't designed to suck fuel. Mount it back near the fuel tank. Closer the better. Mount it so the inlet is lower than bottom of the tank if possible.

It is a vane type pump and the vanes will wear or break if they get crap in them from the fuel tank. You need the filter between tank and pump. Normally I would never do this but on a vane type pump it will help keep the vanes intact.

They say wire through a relay which means to me that it will draw a bunch of current. I'd leave the oil pressure switch out. To the uninformed, there are aftermarket oil pressure switches set at 15psi or thereabouts which DO turn off the pump before a regular oil light would come on. I would put an on/off switch somewhere so you can turn the pump off as a primitive antitheft device.

The literature says 7psi output which is too high for Carter, Edelbrock and Quadrajet carbs. It's on the edge for a Holley. I'd use a regulator without a return line to knock down the pressure.

Well any pics of electric pump set up on a car would be nice to see.I'll be using a 850 mighty demon carb.

I don't have any pics of it as I will have to go out in the garage and jack my car up to get under and take a pic. If its not to cold tomorrow I will go out and crank up the heat and see if I can get a pic for you. And yes I have a filter mounted right there also as I use my filter there before the pump and a stock metal filter in the line up by the carb which I think I have a pic of that one by the carb. You can see the fuel filter I use up front on the pass fenderwell right before the fuel press regulator. Ron

Mine is in mounted on the forward wall of the axle tunnel, with a canister filter in front of it. Any older car has plenty of room there. Mine is slightly above the pickup, but I have not had issue. I also run a bypass line with a one way check valve around it, as I also have a mechanical pump and only use the electric for priming or at the track. The mechanical pulls around it when it’s not on. It should also be wired with a relay.

I fabricated a bracket and mounted the pump and filter to it and pre-wired it. Then just had to mount the bracket. It made the process much easier and I then knew without a doubt that the plumbing was tight and well fit. The relay is mounted on the arm of the bracket you can’t see here. I drew power from the switched side of the battery cutoff,

I see the OP has asked about mounting it in the engine bay on the inner fender.... don’t do that. Just because you’ve seen someone else do it doesn’t mean you should copy their mistake. The pump will wear out fast because it’s not designed to pull and you’re exposing it to the heat of the engine compartment.
