Being the old fart that I am, I still don't have the confidence in an electric fuel pump that I do in a mechanical pump, justifiably or not. It took a few years to accept HEI ignition as reliable too. Here's the dilemma, fuel injected motor without pump provision,gets carb. We all know it won't need a lot of pressure and flow is not an issue. What pump do I buy with reliability #1 quiet #2 and the way prices are all over the board, price #3. Also keep in mind if the pump fails it will likely be on a weekend a long way from home.
I have run electric pumps for years and the only pump that ever failed me was a high dollar holley. After that I went to AC and have never had one fail since. I had the same type motor situation that you have now. All that being said I always carry a spare and the only time it got used was when my buddies mechanical pump failed and we got him home with my spare.
I've been running electric fuel pumps since dirt was invented....................well at least since the 60's. Have used Carter, Holley, and Aeromotive. Prefer Aeromotive because I have used and abused them and they have never let me down. IMHO
I have used the Carter Rotary pump and Holley low pressure regulator with no problems over the years. Beware the made in Mexico solenoid type pumps, I have four and none work any more.
I'm presently running a Holley Black pump. It works fine and is reliable except it is noisy as hell. Obnoxious noisy. I'm going to switch it to a Mallory 110. It's a much quieter pump and I'll be able to hear my quickchange again.
the small inline type of pump sold by many brands? i put a 6v one by airtek on my es*** because i was having problems with the vac*** can, but i took care of it and it just sits there never even connected the wires. i have used a few and had mixed results, i figured the small inline type was like an o.e. part and would hold up, guess not. when i put the rover enigne in the es*** ill have to run an electric, i thought i would get the sam epump but 12v, i actually have 4 electrics si***ng in my cabinet, a holley red, blue, mallory and a carter, so i guess ill take my pic and keep a spare.
I did this search not to long ago and the overwhelming choice is the carter street pump sold by summit for about 80 bucks. I have a mallory 70 for my 40, hope it holds up.
I'd go to the O'riley's are the NAPA and get the one I thought would do the job for me. Most of those stores will carry the same inventory if you break down. I have TPI and carry a new pump as a spare and have not needed it away from home. Fingers crossed..
Seems like the Holley red pumps are affected to a great degree when they run hot. To that end, make some heat shields. And run a relay so you have full battery voltage to the pump - which is the most important thing you can do. What seems to be happening to mine since the heat is on here - 102* F - it byp***es internally and the pressure drops to 2#-3#. I have had the red Holleys internal regulator stick and you only get 1/2# - 1#. An easy fix, open up the pump, pull the Teflon piston and spring & clean up the bore with some worn 400 grit wet/dry. Reason I'm doing the Holley fandango is, my mechanical fuel pump went south and with 3-4 new Holleys - trades etc. - I decided to use one of them and carry another for a spare. If . . . big word that 'if' - I have to swap pumps it'll be a ***** cuz the pump is under the body. To that end, I have some hoses made up and I'll hang the "get-home-Holley pump from a radiator rod, plumb er in and connect a temporary wire controlled by the ignition switch. I know they work better in the back, but they work fairly well in front and if you're just trying to get home . . . who the hell cares? A # or a # & a half of fuel pressure will take you a long way at part throttle.
I go to the junk yard and i get fuel pumps out of 1980s jags And a holly reg from you local speed shop as they make about 120 pounds of p.s.i i was told .They have sweet mounting brackets and there in the trunk easy to take out . New they cost about 180 they work better then any pump ive ever payed for and never have one died on me and there quit . I payed 40 dollers for two , one for a spare . I had a jag with 200 thousand miles on it and i have that pump in a car that is still running ,had a new holly lasted maybe a year and left me on the side of the road
holleys are affected by mounting position too. i found out the hard way, i figured you could mount it any which way. what holley reg do you use to go from 120 psi down to 5-7? i have heard of guys using a mallory reg in this situation on trucks that they swapped from efi to carb, and kept the in tank electric. if you mount them on rubber, in rubber, rubber here, rubber there, with some either rubber hose or braded line, they are a little better with the noise too.
I think it is 120 p.s.i. thats what i was told and i think thats a holly reg i forget i bought it a long time ago . just slung under my caddy with the jag stock mount it has a rubber lining on the mount and is under my drivers door and i cant here it unless the doors open and i have no door panels. Jag pumps rule
I use Carter P4070. They are as reliable as any and more reliable than most and fairly priced as well.
I have been using Carters for many moons ( rotary type ) <br> I have one on my merc now! AC are good also
So rotary is the way to go over a solid state, what ever that means ? What are those inline looking pumps? I understand about closer to the tank the better, possibly a relay, and a pre-pump filter.
