New LiftPump/Regulator Installed

gordon , i just looked , it looks like you have the pic linked to a picture on your harddrive , you need to attach it or host it from an internet site ...



try it again .

Mopar, I misunderstood on the regulator/pump failure subject. It seems that just about every pump that has been tryed thus far has not worked. I do not think anyone has tryed the type I am using.



I just got off the phone a little while ago with a Mallory tech. I expressed my concerns with the location of the regulator. He stated that on gasoline engines the regulator could be up to 3 feet away. He also stated in the application I am using (diesel) that this rule could be bent because things are not so critical.



As far as the Mallory regulator, I am sending it back. Jeg's advertises it to be fully adjustable from 3-65 PSI. This can be done by using either a light, medium or heavy spring in the regulator. Come to find out, Mallory does not offer the medium or heavy spring anymore with the 4309 regulator. At the current time I am seeing 14 PSI at idle and 12. 5 PSI at 105mph, uphill with 32 pounds boost. The regulator has the light spring and I have the adjustment cranked all the way in. With the light spring it is rated at 3-12 PSI.



It appears the Aeromotive (027-13301) is the way to go. It has a range of 3-20 PSI with the standard spring and 20-65 PSI with the high pressure spring that is included in the kit.



Mopar, was you able to see the picture I tryed to post? I am totally lost when it comes to trying to do anything more than the basics with a computor. Mopar, what I can do is send you the picture and maybe you could put it up. Send me an e-mail. Gordon.

I've been using my BG220HR for about a year now and I've got 32,XXX miles on it. It comes with a regulator that I mount pre-filter and my post-filter PSI's never drop below whatever I set the regulator out. Meaning that if I set it at 14 psi, my post-filter pressure STAYS at 14 psi. I've never had any problems with my pump. IMO, it's great!

gordon , you have to have the image on the internet somwhere , you used to be able to attach pictures , and it was stored on the site here ???? no clue , i never attached one on this version of the BB .



anywho my concern is a pump living a long time and not causing problems by having to muchh pressure or to much pump . HVAC tried the holley pump , didn't fare well for him .



my concern with to much pump is heating up the fuel which will diminish some of its cooling capibility ...



with a 220gph pump, like the BG, and a regulator you are moving a HUGE amount of fuel constantly , once the tanks gets low , you have the potential to cause the fuel to foam , which is easy to do with diesel fuel . running that big a flow back into the return line that is already in place has the potetial to force fuel back toward the engine and the injection pump unless you put in a check valve upsteam of your tap ... this is the way i see it .





seems one year is the norm for all the pumps to date, i'm going to disect the pump that just died , i have a rebuild kit , wonder if it will fix it .

Mopar, the Holley pump I am using is very different from the one that HVAC tried. I believe he was using the Holley blue pump which has mega flow. I agree with you 110 percent that we do not need flow we need to be more pressure concerned and orientated.



The (512-103) Holley pump is an inline pump. It has capabilities of 45PSI@35GPH. It can be regulated to 15PSI@50GPH. When you consider that the fuel filter/head can flow 45GPH this is as about as close as it gets to a perfect match at least on paper. I am also told that this pump is actually manufactured by Walbro. Walbro makes world class in tank as well as in line fuel pumps.



Another promising feature about an in line pump is that it can be mounted close to the lower portion of the frame. This should help keep gravity flow in motion. I think that the factory Carter is not only struggling because of the distant location from the tank but the plane it is on is hampered as well.



I would also agree the regulator should be closer to the components being regulated. At the same time I am not quite sure it is real critical in this application. If I can maintain 12-14 PSI under full load, a little fuel pressure hopping does not bother me.



At the current time I do not drop below 12. 5 PSI and I am maxing out the regulator's capacity with the 3-12 PSI spring. I am looking forward to trying the Aeromotive regulator.



All of this is just a bunch of trial and error. Afterall, the easy thing to do would be to go back to the dealer. That is nothing more than a temp fix. Will this pump I am testing work? I do not know.
