savageskaterkid Posted May 8, 2006 Share Posted May 8, 2006 Would this fuel pump be enough to run a boosted L28. http://cgi.ebay.com/ebaymotors/MSD-HIGH-PRESSURE-ELECTRIC-FUEL-INJECTION-PUMP-2225_W0QQcmdZViewItemQQcategoryZ33555QQitemZ8063481316QQrdZ1 It seems as though it would be sufficient, but it said it can be used as a booster pump, does that mean that it can't be the primary pump?

jfairladyz Posted May 9, 2006 Share Posted May 9, 2006 That pump will flow enough fuel to flow quite a bit of power. It states right in the description that it can be used as a stand alone pump. Whether it's good for your application would be determined by how much power you are planning to make. Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted May 9, 2006 Author Share Posted May 9, 2006 250 max, for now. But once I get the funds I'm gonna drop an RB in at some point, so I'll end up rebuilding again later. Quote Link to comment Share on other sites More sharing options...
Doug71zt Posted May 9, 2006 Share Posted May 9, 2006 It is the same pump I'm using in my Z. Mine is branded NOS, but they are the same. I've got no problems with it in my application. It is reasonably quiet in the Z. You can use the stock reg with it with a decent sized return line. I´m running 3/8 supply with the stock 5/16 line used as a return. If you've ever been in a Z with an A1000 installed, you know you wouldn't want one in your daily-driver. I´d double up two of the MSD pumps in parallel before using one of those in my car. YMMV Doug Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted May 10, 2006 Author Share Posted May 10, 2006 with this fuel pump, what would be a good FMU to run, like pressure wise? Would 10:1 be sufficient? I've seen them as low as 8:1 and as high as 12:1 Quote Link to comment Share on other sites More sharing options...
evildky Posted May 11, 2006 Share Posted May 11, 2006 thats the pump I am using and it's the only one, I think they just don't want people to try running it an an internal (poeple do all kinds of stupid things) it flows fine but you need stiff large diameter hose feeding it or it will suck the hose shut ( I ran 1/2 aluminum tubing to feed it and 3/8 to the rail and I'm running an aeromotive rrfpr, and I seem to recall my pump was only about $80 from summt but that was a few years back Quote Link to comment Share on other sites More sharing options...
z-ya Posted May 11, 2006 Share Posted May 11, 2006 I've used this pump on a bunch of applciaitons, including a 326WHP L28ET powered 240Z. It has flow for close to 500HP, and you can't be the price. So far they have been very reliable. BTW, you can get it a Summit Racing for $89.88. Quote Link to comment Share on other sites More sharing options...
savageskaterkid Posted May 11, 2006 Author Share Posted May 11, 2006 actually already bought this, its 92, but with free shipping, so its not bad at all. but what FMU should I run? Quote Link to comment Share on other sites More sharing options...
Pyro Posted May 11, 2006 Share Posted May 11, 2006 Bell Engineering FMU. It has an adjustable ratio. Use it after the stock fuel pressure regulator. There are two different Bell Engineering FMU's, one for boost and one for NA. Make sure to get the right one. You really need a fuel pressure gage in the car to tune the FMU. I use 55 to 60 psi of fuel pressure for 7 to 8 psi of boost, 70 to 75 psi for 9 to 10 psi of boost, 80 to 85 for 11 to 12 psi of boost, 90 to 95 for 13 to 14 psi of boost using stock NA injectors. The ratio you will need depends on the injector size. One msd 2225 will only manage about 70 psi during high flow. I use two MSD 2225 in parallel with one on a 6 psi pressure switch.

savageskaterkid Posted May 12, 2006 Author Share Posted May 12, 2006 seems like your using a 10:1 on stock N/a? I'm using the stock N/A injectors for now too. Quote Link to comment Share on other sites More sharing options...
z-ya Posted May 12, 2006 Share Posted May 12, 2006 The stock regulator will work just fine, unless you are looking for bling. Quote Link to comment Share on other sites More sharing options...
