seems like its 50 50 here on a stock fuel lift pump or a electric fuel pump.i think what i saw here is if u go electric it has to be a flow through pump and just bypass the old stock pump

 

yeps, if you go electric you bypass the mechanical pump - reason is the the mechanical pump woks on pulses while the electric provides steady flow, these two can fight and often result in a ruptured mechanical pump diaphragm and a crank case full of fuel. You can actually remove the mechanical pump and use a block-off plate for a big-block Chevy to close the opening in the engine block where it used to go in.

 

do you have to use the block off plate??? can t u just plug the fitting s on old pump

 

Why not block it off and gain all that horse power that it takes for the mechanical pump. lol

I don't guess you even need to plug the fittings if you leave it on there.

 

a block off plates only a few bucks.
i noticed the engine ran quieter when i took my lift pump off.tho it may have been weak as to reason why,i dunno.but much quieter.
you got the right idea tho.pushing fuels better than pulling it imho.no more air intrusion hard starts.just have to watch for leaks like any modern day fuel system of course.

 

Ford I have an 84 that still runs on the old antique outdated system that it came width and have driven it and depended on it to get me from point a to point b for years.

It has proven to me and everyone else that has had one forever to work and be as dependable as any other pump that the manufacturers have ever come out with and far more dependable than many electrical pumps even the ones that. These pumps don't care if you routinely run the tank low. they don't care if you happen to run out of fuel. They have a long lifespan at least equal to any electric pump. Have you ever wandered why semi's don't have electric pumps when one is expected to run over a million miles under every imaginal conditions.

You keep recommending everyone to get modern and change there system to be like yours, and act like it is the best thing since sliced bread and make us that still use the time tested sytem sound dumb for not cutting our lines and installing a different system when we have one that works and there is no performance advantage. Ford never used an electric pump until it went to fuel injection and needed 90 pounds constant pressure something the mechanical wasn't capable of. they and every other manufacturer also installed precautions to shut down the pump in case of an accident have you ever seen a pinhole in a fueline it mists the fuel even at low pressure, so your system is not what you would call modern it is what we used in the sixties when we built something that REQUIRED more fuel that a mechanical pump could handle.

I could care less what you or anybody runs for a pump, but we are not stupid for running a time and mile tested, tried and true system. A lot of shops will not even install one like yours for liability reasons.

 

I also run an electric pump on mine, but it is only because it was in the tank already when I did my swap. Personally I like the old manual pumps. You don't have to worry about electrical conections or the pressure regulator going bad like I have. When mine was still a gasser the power wire to my pump shorted out on I75 going into cincinnati at 6:30 in the morning and I had to splice it back together along the side of the road with cars and semis blowing past me at 70mph not fun! If my in tank pump ever goes out I will be putting in a new lift pump not the tank one. I figure that way even if my alt goes out I will still get where I am going with only needing enough power to hold the fuel soleniod open.

 

I am not saying not to run an electric pump I DONT CARE and I had one on my first one mainly because I had one, and was to cheap to buy a new pump to see if that was what was getting diesel in my oil. It was and I left the electric pump on there. This rig had the seat tank and brought me almost 300 miles home one night with out a miss as long as I was on the top half the tank with a dead electric pump. if it would gain me a horsepower I would have been running them all along. Another thing electric pumps rely on fuel to control the heat, The reason there is no wuarranty on an electric pump if you don't replace the filter when you install the pump, is a stopped up filter has already been overloading the pump for a while and when you have as big of a filter it will go a long time with a half stopped up filter causing your pump to run hot and by the time your filter gets too stop to run the electric pump has all ready lost a lot of pressure. Your intank pump will put out about 60 pounds of pressure so even if it was dead it will still put out enough to run an IDI. One thing I would be leary of though is an electric pump wears and puts very very small black powdered steel in the fuel and I'm not sure a stock diesel filter will catch it all and it will not be good for the close tolerances inthe IP, so keep a clean filter and don't run your tank low especially in the summer months.

 

umm what? lol.
run your truck however you want star.this doesnt mean your stupid.
re-read what was asked and re-read what i answered.there's nothing there directed at you nor anyone who runs a stock lift pump.

 

Maybe it was the way I have been reading but the way we refuse to modernize makes us sound stupid or dumb, not saying I'm not either. lol

I try really hard to give advice on here that can't be a problem down the road. I have never advised anyone to install an electric pump but have to install a boat bulb if they have one that is hard to start after installing a filter, they work and have no drawbacks.

I don't know anybodys mechanical ability or the mechanical condition of their trucks and would rather see them fix it right one time,I know from experiance it will be dependable way longer than most people own there trucks. Not me but most people I have one that I've had for just a little over 25 years and it still runs I don't drive it antmore but it isn't because of the motor or drive train. It's the one joe keeps wanting a picture of and it's just an old work truck.

 

Star, he mean that if the guy is about to run an e-pump anyways, might as well remove the old pump and use the Chevy block-off plate. He didn't say that the OP should ditch his mechanical pump for an electric unit, but that if he does do that then it may be beneficial to entirely remove the mech pump instead of just leave it sit there and do nothing but make noise.

 

I;m just giving him a hard time, because every time someones truck won't start he always comes back that here is one more that would not have any trouble if he would modernize. lol

 

Eh, maybe, I don't keep track of who posts what - but when I replaced my mechanical pump I did so with another mechanical pump (domestic-made too!), I tend to fill up at 1/4 tank on the gauge which is really like 1/3 in the tank so I don't risk running outta fuel. I also run locked-up mechanical fan so I always get all the cooling I need and then some, and if there was a way I'd also run mechanical fuel shutoff too

 

oh lol!
well star,its a good thing everyone doesn't switch over.otherwise you'd have no more fun answering air intrusion questions.

nah seriously tho, i just use the word "modernize" here,as its just a widely used device on many vehicles now.not to imply anything good nor bad about the stock lift pump setup really.if you would rather have the engine suck the fuel rather than have it pushed like stock,well hey,if it wasn't good enough they wouldn't have built 'em like that in the first place right.
some of us just like change things from stock thats all.the electric pump conversions started way before i got my IDI.i just like it better,id never imply people who run stock lift pumps where silly for doing so.

 

It's all good and mine isn't exactly stock, I can never leave anything stock, it can always be better. If I liked the way they come from the factory I wouldn't have a turbo, and would have a garden hose for exhaust.

But when you say modernize that is the oposite from the reason I like the idi's, it would be easier to drive a new one.
When my son got out of highschool he needed a new pickup, so we go to town to see what kind of deal we could make. We went in my dually,it had a new paint job and looked pretty fair at the time, but he is wanting a chevy crew cab Diesel was out of the question (he couldn't afford the payments on a new diesel) so we are driveing a 4X crew 1/2 ton loaded to the gills, and I was rideing in the back seat, so the salesman had in his mind he needed to sell me on this pickup and kept turning around and asking me how I liked this option or that one. I finall ask him if he noticed what I was driving, when he said yes I told him if intended to sell this thing we were riding around he had better ssell my son on it, that he wasn't near good enough to sell it to me.
