Scottie-GNZ Posted September 24, 2001 Share Posted September 24, 2001 Anyone found a good low-cost hi-perf EFI pump? A lot of folks have me about EFI pumps and the $250+ asking price for the really good pumps can hurt a pocketbook. Surprised no one has come up with an alternative.

SHANE Posted September 24, 2001 Share Posted September 24, 2001 right now i use an MSD pump from JWT. i think it was around $140. good for 550HP. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 24, 2001 Share Posted September 24, 2001 Scottie, look in the search feature, someone mentioned using a Ford Van or Truck Fuel pump that was pretty reasonable, sounded like a pretty good pump for the $.

74_5.0L_Z Posted September 24, 2001 Share Posted September 24, 2001 I am using the MSD P/N 2225 EFI fuel pump. I got mine new for $105.00. It flows 48gph at 39psi(enough to support about 400 hp). This pump is small, relatively quiet, and has work flawlessly for 1.5 years so far. I tried an Ford F250 pump before using the MSD, and only got 25 psi. The Ford pump requires a low pressure pusher pump ahead of the high pressure boost pump. The MSD pump stands alone, and mounts inline. Be sure to mount your inline fuel pump so that the inlet is lower than the outlet of your fuel tank. Also mount the pump as far back as possible. Electric fuel pumps push fuel well but are lousy at pulling fuel. Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted September 24, 2001 Author Share Posted September 24, 2001 Thanks, all. Dan, for folks like myself, mounting the fuel pump inlet lower or even equal with the tank outlet is impossible with the sump. hard to say if it is causing a problem but I have no choice.

Guest Anonymous Posted September 24, 2001 Share Posted September 24, 2001 You all may want to look into a Ford pump for the 4.9 (aka 300 ci) staight six. My 1993 F150 pushed 50-60 psi at the mainfold. I can't remember if it was a frame or a tank mount, but a trip to the parts store would iron that out. Or just call Ford. just thought I would pass that along considering TPI 355 so I have been following your threads. Which system are we talking about when looking for pumps for you all. one more quick side note. not to be chicken-sh@t with fuel pressure but I know from past exp. that I could restict the return line to boost pressure by a few lbs. jake Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted September 25, 2001 Share Posted September 25, 2001 I use a Ford van fuel pump (bosch) without a pusher and get an even 43psi out of it with the regulator I use. Quote Link to comment Share on other sites More sharing options...

Modern Motorsports Ltd Posted September 26, 2001 Share Posted September 26, 2001 Originally posted by Scottie-GNZ:Anyone found a good low-cost hi-perf EFI pump? IMO, I'm running a bosch I'm liking a lot already. It's very quiet, mounted with rubber all around and 2 large stainless hose clamps. I've heard enough noisier non-OEM/aftermarket type pumps and wanted a truly quiet one and hoped OEM bosch quality would treat me well, their R&D has to be good. The Ford pump someone else mentioned was another brand, can't recall which one that was though (airtek?). Mine had a 5/8's inlet on gravity side and an M12 fitting on the other side that I adapted over to a GIC fitting to hose barb....be nice to just have a nice GIC hose made up some day. good luck Quote Link to comment Share on other sites More sharing options...
Dan Juday Posted September 26, 2001 Share Posted September 26, 2001 Scottie, I listened to Jack, 66coupe. I paid about $120 from Napa. It's very quiet. It puts out about 45psi. It was made to run an EFI 351. It does NOT need a "pusher" pump. That is a bunch of baloni. Ford uses a surg tank in that van in the same way it is described in the JTR manual. A sump does the same thing as a surg tank. Mine is mounted beside the tank, above the sump, and it happily sucks up the fuel. When I fired it off for the first time it self primed with only about a quart of fuel in the tank. You will need to buy adapters (Earl's and XRP make them) to connect AN -6. If you want more info let me know and I'll get you part numbers. Thanks again Jack. Quote Link to comment Share on other sites More sharing options...
Jason81NA,82RBtt Posted October 6, 2001 Share Posted October 6, 2001 Right Now I using a F150 4.9L rail mount BOSCH fuel pump. Using my adjustable FPR I have had it to as high as 80psi. I wanted to make sure that it produced enough psi for my car on N2O. It is a good, quite pump.A friend gave it to me after he installed a 289 with a carb, and did not need it anymore. I would say that these pumps where plentful at parts yards. Good luck Jason Quote Link to comment Share on other sites More sharing options...
Scottie-GNZ Posted October 8, 2001 Author Share Posted October 8, 2001 The question was not asked for me. I run a Pierburg. I have had several queries about what pump to recommend and several turbo cars need an upgrade but do not necessarily need a pump rated at a gazillion GPH and costing $250+ Quote Link to comment Share on other sites More sharing options...
R0N Posted October 16, 2001 Share Posted October 16, 2001 I don't know how to do the formulas... The Vortech inline pump produces 50 gph at 70 psi. Does anyone know who much HP can this pump support? Thank You.... Quote Link to comment Share on other sites More sharing options...
R0N Posted October 16, 2001 Share Posted October 16, 2001 I just found this on ebay (dutch) http://cgi.ebay.com/ebaymotors/aw-cgi/eBayISAPI.dll?ViewItem&item=596760885 It's 70gph @ 85psi for $50. He has 300 in stock brand new. Does anyone know how much HP this can support? [ October 16, 2001: Message edited by: R0N ] Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted October 16, 2001 Share Posted October 16, 2001 Umm, I'd want part number and manufacturer information before I'd bid. Who rated that pump, what does it fit, and what sorts of hookups does it have. He's left too much to the imagination IMO.. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted October 17, 2001 Share Posted October 17, 2001 Definitely check out the flow @ the pressure you need to run on your efi system. Basic measure (if I remember correctly is .5 lb per hp per hr. Gas weighs (?) ~6.87 lbs/gal (again - thisis the measurement I REALLY can't remember). Figure ~450-500 HP AT THE RATED FLOW - what happens at lower pressures used on most systems? Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted October 18, 2001 Share Posted October 18, 2001 "I have had several queries about what pump to recommend and several turbo cars need an upgrade but do not necessarily need a pump rated at a gazillion GPH and costing $250" Conservatively my bosch will support 450hp which is plenty for me. I used figures from the SDS website for fuel consumption ranges. I mounted it on the stock bracket with two large hose clamps and wrapped the pump in some VERY skookum 1/2" thick rubber (typically used for bridge bearings....soft enough for great damping but no wear....used same on base of radiator mounts)" SDS has fine info for calculating fuel needs. Just IMO, but I'd rather have an OEM brand pump which is known as damn good (ie. bosch) than aftermarket where far fewer units are made and quality for electrical can often be less than desirable....the quality and quiet bosch had me sold).

awd92gsx Posted January 27, 2002 Share Posted January 27, 2002 How about Walbro 255lph's? They've succesfully propelled many cars into sub 10's...They only cost bout $100 or so... Quote Link to comment Share on other sites More sharing options...
