I plan on replacing the mechanical pump in my 88 F250 with an electric pump. I understand that I need the plate to block off where the lift pump is. What PSI range should I look for when selecting a pump? What PSI does the IP need coming into it? Any pump recommendations? Also, how should I wire the pump up?
thanks-

What is the benefit of having a electric pump? If you were trying to start your rig would it force too much fuel into the engine if you have problems starting it??

Planned upgrades are a new and better turbo and larger exhaust pipes than the 21/2s that are already under the rig/ would like a 6 spd tranny but dont know if that is a feasable or smart investment yet.

you'll need to run a lower pressure pump like the holley red, they produce about 5lbs pressure. Some here like the carter pumps, opinions vary but you will be glad you installed the electric. Use a relay with 12v direct and switch power to it off of the ignition switch. some hook up a oil pressure sensor in case of a wreck it will shut off power to the fuel pump. real easy job takes a hour or so. good luck

One of the major benefits is when you are trying to bleed air out of the IP lines to the injectors you don't have to crank the Autolite out of the starter just to push fuel to the IP. Also, when you change the fuel filter, all ya have to do is turn on the key, walk back to the filter and push in the schrader valve to let the air out, walk back and start the engine. It might stumble a little, but it'll stay runnin'. The e-pump can't/won't force fuel thru the IP. My engine will run about 5 miles on just the fuel in the line if I have accidently turned the e-pump switch off. I leave it on and have a low oil pressure switch in the line to the e-pump and a DPDT switch to bypass it if/when it is necessary. Ok, how confused are you now?

I would advise removing the stock fuel pump and putting a plate over the hole.the $4.99 for the big block chevy block off plate is much cheaper than if the now unused stock pump comes apart and distroys the $5,000 engine.Some have just hooked the E-pump into the fuel system and let it pump thought he stock block pump.BIG mistake.If the diaphram lets go you will fill the crank case with diesel.Even if the stock pump is left on there the arm can fall off and do UGLY things when it bounces around the crank case.

Does NAPA (or similar) carry these Holly Reds? How did you guys
mount them? I can tell my lift pump is in need of replacement.
Probably worth the little extra effort to put in the electric.
TIA!

I recommend removing the mechanical lift pump and installing a electric pump. I have and those that have heeded my words will confirm that it solves lotsa of problems and if you ever run your tank dry, it's sooooo much easier to bleed the air from the lines with the e-pump.
You can get the Facet-Purolator Pump available from NAPA - Belkamp label, NAPA Part# 6101050, only $36 out the door. Mount it on the frame rail, just in front of the fuel tank selector valve. They push better than they pull.
You MUST also buy a 'Big Block Chevy Block Off Plate while you are at the parts store ~ $5. When you remove the mech pump you cover the hole in the block with the 'Block-off plate'
When you change the fuel filter, next time, you don't have to worry about filling the fuel filter with diesel before you spin it back on. After it's tighten up, just turn on the e-pump and it'll fill right up. You can get a Holly Red pump from Summit Racing for $95.88. You should also get the Oil Pressure Saftey Switch also available from Summit for $19.88. You can buy a generic Oil Pressure Saftey Switch that 'open'(turns off the current/circuit) when the oil pressure drops below 4-6lbs. I have a by-pass switch on my oil pressure saftey switch for those times when I want the pump to pump fuel up even though the engine isn't running. OkieGringo
Mounting is simple. Back by the changeover valve you will find some predrilled holes in the drivers side frame rail. Most use them.

Advance auto parts has them on sale right now on the website.$95 plus I think it has free shipping.You just bolt it to the frame just past the selector valve hicky and wire it up.Make sure you have a oil pressure switch too.Saw what happens to a race car when they didn't do that.115 Octane burns real perdy.Too bad that Ford Torino also burned real pretty too.What a waste.First time at our track,throttle hung wide open,head long into the wall,fuel pump kept pumping the go go juice out.They had to use EVERY extinguisher in the house plus the water truck.And that is why we have rules against Electrics on our race track too.

What exactly is a Holley "Red" pump. Anyone have the specs required to fuel these hogs?
Also, Is the fuel in the filter/IP enough to get it fired up to the point where you build oil pressure, activate the pressure switch, and the e-pump starts running?

Yes. My engine will run about 5 miles on just the fuel in the line if I have accidently turned the e-pump switch off. OG
