WillBilly53 Posted October 6, 2003 Share Posted October 6, 2003 could you all give me some advice and info on the electric fuel pumps? i know there have been a few posts on this subject but i couldn't quite find the info i needed.also i should say that i plan on driving and enjoying this car and i'm not concerned about winning any shows.also i plan on installing an electric wiper motor.so my questions are...will i still need the original pump? if not how does the fuel line mount to engine? also someone mentioned that most auto parts stores sell the 12 volt electric fuel pump. is it universal or is there a specific model/make?thanks!

The Old Guy Posted October 6, 2003 Share Posted October 6, 2003 The bellows type electric pump can be used in conjunction with a stock pump. The stock pump will pull fuel thruogh the electric ,and you may only need the electric in hot situations. I have run electric pumps for years, and they are nice when the car has been sitting for a long time. You can fill the carb and the car starts like it was fired yesterday. Many of the older cars suffer from vapor lock ,and the electric pumps allleviate this problem entirely. Link to comment Share on other sites More sharing options...
Guest imported_MrEarl Posted October 6, 2003 Share Posted October 6, 2003 So how should the pump be wired. I have one in my 54 Roadmaster that was installed when I got it and it is wired straight, in other words the switch doesn't have to be on for it to run. I'm always afraid I am going to forget and leave it turned on some day.What will happen in that case?? Link to comment Share on other sites More sharing options...
Guest imported_NikeAjax Posted October 7, 2003 Share Posted October 7, 2003 I mounted my electric fuel pump to the frame at the hump for the differential, and then wired it to the ignition switch, yeah it's a long piece of wire, but I haven't had any problems. I also removed the old pump, it’s dead weight, and more stuff to clutter up the engine. There is also an electric wiper motor out there that has two speeds, sorry I can't remember the make, I got it from Buick World; this is great because it doesn't slow down when you're speeding up or going up hills. Yeah, my Buick is my everyday driver, and it's scarier than hell when it's raining and you can't see what's in front of you because you want to pass someone, a change of underwear is often needed. Also, might I recommend electronic ignitions if you're not showing the car, gee they're swell and it makes tune-ups a snap! I have an MSD, and it's nice to have that extra power with cheap gas, I don't have any pinging! Link to comment Share on other sites More sharing options...

YellowLark Posted October 7, 2003 Share Posted October 7, 2003 MrEarl,Sounds like you have a toggle switch for the fuel pump which goes directly off the battery.I guess if you leave it on, it will draw down the battery, but probably will not cause fuel leakage.

YellowLark Posted October 7, 2003 Share Posted October 7, 2003 You can buy a generic auto fuel pump. Delco makes them, and they are available at local auto stores. You only need a low-pressure unit, not a racing model. I kept my stock fuel pump. It performs as the primary pump after the electric is used for starting. It provides redundancy to the system. If you buy a racing-type high-pressure electric unit, the stock pump will not be able to draw through it. Link to comment Share on other sites More sharing options...
old car fan Posted June 21, 2012 Share Posted June 21, 2012 I would never use a electric pump,unless it was born with it,and this being AACA,i doubt it.On a shakedown run ,sure,get the bugs out.Buy a rebuild kit for your pump,to accept our junk gas,and you will be fine.

BUKE Posted June 22, 2012 Share Posted June 22, 2012 Boy do I agree with you Mike. I can drive by 1940 century without an electric pump in 60° weather. Let me try and drive just 20 miles in 75° in that big old Buick would stop dead in the 3rd Lane. I learnt to put the electric fuel pump right under right rear door and go right through the mechanical pump and most people know I drive her everywhere but without that pump on A A A . I recommend a electric fuel pump on all straights just for safety and peace of mind. Have a great Buick day FRANK Link to comment Share on other sites More sharing options...
michaelmis Posted July 23, 2012 Share Posted July 23, 2012 An electric pump to prime my car on cold mornings/hot starts was very useful.Links below have description of my car, plus lots of other folk and all sorts of cars and configurations.http://forums.aaca.org/f162/1950-electric-fuel-pump-question-309558.html#post997639http://forums.aaca.org/f120/electric-fuel-pump-177403.htmlhttp://forums.aaca.org/f120/6v-electric-fuel-pump-178548.htmlMike Mbuick 1950 for sale roadmaster super special australia Link to comment Share on other sites More sharing options...
Guest RonJar Posted July 23, 2012 Share Posted July 23, 2012 My 38 Century, converted to 12 volts, has a low pressure electric pump, 2 to 4 psi, which I mounted on the crossmember right in front of the fuel tank with a filter between the tank and pump. I wired it, with a fuse, to the ignition side of the key switch, so as soon as I turn the key to "ON", the pump comes on and when I turn the engine off, of course the pump stops. The windshield wipers are two speed electric so vacuum for the wipers is not an issue. The whole thing is very reliable.RonJ Link to comment Share on other sites More sharing options...
buick5563 Posted July 24, 2012 Share Posted July 24, 2012 RonJ,Are you still running your mechanical pump, or just the electric? Link to comment Share on other sites More sharing options...
FLYER15015 Posted July 24, 2012 Share Posted July 24, 2012 Mike,I installed a 6 volt low pressure electric pump on my '40 LTD the day I brought her home from Denver. located the pump on a cross member just in front of the gas tank, with a BIG clear plastic filter between the pump and tank. Electrics like to push gas. They don't like to pull gas. I put a toggle switch under the dash, and wired it straight to the battery (with a fuse in the line). She sits all week and it sure helps prime the system, so as not to grind on the starter. Once she fires, I turn off the pump. That is until I have to climb a hill.Up here @ 8500ft we have no air, and it gets hot (just like Austin). With only 10% corn juice available here and long hard pulls in every direction, "vapor lock" is a way of life.Mike in Colorado Link to comment Share on other sites More sharing options...

buick5563 Posted July 24, 2012 Share Posted July 24, 2012 Thanks Mike,I run electric pumps on all of my cars, I just didn't know if you were running it in conjunction with your original pump. The reason I asked is that my fuel pump was slobbering so badly after the trip home from the Nationals this year, that I decided to pull it. I haven't tried going highway speed yet running ONLY the electric. Link to comment Share on other sites More sharing options...
Rooster Posted July 25, 2012 Share Posted July 25, 2012 When I re-built my 1929 all I ran was the stock diaphram type pump. Had all sorts of issues with vapour lock. Installed electric pump in conjunction with stock unit and to prime after sitting for long periods and to blow vapour lock through at any sign of it ( gets hot here Down Under ) Simply THE BEST thing I ever did to that car and I would advise owners of any Buick driven in hot weather to instal one. Take it off for when you want to win trophies then put it back on. Link to comment Share on other sites More sharing options...

Ken, does Irene still have the electric fuel pump set up the same way it did when I had it, with the toggle switch? How is my ex doing by the way.

Rooster Posted July 27, 2012 Share Posted July 27, 2012 The pump is still there and controlled by the switch. But I re-built the mechanical pump and use it for running. The electric is used for priming, same as the '29.Irene is running excellent. Developed an exhaust manifold gasket leak. I'm loathe to take off the manifolds for fear of shearing bolts. I'll have to figure out a way of plugging the area with Devcon or similar liquid metal. Link to comment Share on other sites More sharing options...

Rooster Posted July 27, 2012 Share Posted July 27, 2012 Cheers, thanks Raul. For those who don't know the history, Irene came Down Under from the Georgia Buick Farm residence of one Mr. Earl. I think it must be close to 5 years now. Link to comment Share on other sites More sharing options...
MrEarl Posted July 27, 2012 Share Posted July 27, 2012 You know Ken, in pulling quite a few manifolds off parts cars, I've never had any problem with the bolts, they generally break loose without much effort. Well I take that back. I had one bolt that wouldn't break loose after tapping on the wrench with a hammer a little. I used a small Makita cordless impact driver that I knew didn't have enough power to shear off the bolt just to put some vibration on it. Applied torque both ways, forward and backward. After that it broke loose with hardly any pressure at all. Again this is on parts cars, I'm sure if I were doing it on a nice and running car, they would all probably break off.

Rooster Posted July 27, 2012 Share Posted July 27, 2012 A lot depends on how long ( if ever ) the manifolds have been off. And if the previous mechanic put never seize or similar compound on the threads ---- I always do. Link to comment Share on other sites More sharing options...
