Mallory 4150 Fuel pump opinions

[Chad Sheets]

I hear this is the beast to have if you want 10-15 psi fuel flow to the injection pump at all times. Who has tried this set up? Is the durability there for continuous opperation? I know HVAC was replacing his Holley with a Mallory at one time. Anyone know if it ever worked out?

I would like to know also how the Mallory works out. I replaced my stock liftpump 20,000 miles ago with a replacement from Carter and it is still working fine, but I would like to replace it with a Mallory and move it back by the tank.

When I talked to Nowell about 6 weeks ago he said the Mallory was working good. He felt it was built better than the Holley unit. I may be calling him again soon to ask him more about it because I may get a Mallory soon. My OEM pump is currently rigged temporarily at the fuel tank pickup.

Mine is starting to act squirly going down the interstate... 2 then 6 then 1 then 5. Cant be having that on Big Red/Rescue 1.

I talked with Nowell about it as well via email when he tried it. Never heard any negatives, so I take it all is well. I got my hands full. Need to do the fuel pump, change converters in the Cuda, and install my Bill K. TC and VB in the Ram. Talk about busy.

What is a Mallory 4150 fuel pump? I am looking in a Jeg's magazine and i don't see this. Holley makes a 4150 carb, that's the only thing I see with the 4150 numbers.

According to an Email response I received from a Mallory tech. their #4140 electric pump is the ONLY model that will work in our application (internally bypassed system).

John, Did the response say whether the connectors will work, or do the fittings have to be changed?

This is a link to the site that had the fuel pump I was talking about. What all is different between this one and the one the Mallory guru sugested?

OK. It says on that site I listed above that the 4140 is a 4150 pump and regulator kitted togather. Same 4150 pump, just in a kit form. Here is the link to the 4140 kit http://www.centuryperformance.com/search_result. asp?Product_ID=MAL-4140

Still dont see why you need a regulator?? The pump only puts out 12psi if I read it correctly. The stock pump is rated at 10psi. And any excess fuel pumped to the injection pump will only aid in cooling and lubrication then be routed back to the fuel tank. Anyone else see a reason for a regulator?

12psi is good , my new replaced factory lift pump puts out 13psi , they list it with a regulator because its usual application is in a car with a carb and a carb needle vavle isn't good for much more than 6-8 psi .

i personally would like to see 13 -14 psi , when you have your foot in it with all the oys on you need all the fuel you can get , i have seen my gauge go to 0 on a full throttle pass , its at zero before i get to the end of the 1320 .

i have a stock fuel pickup from a members ram , he changed it out for a JRE 1/2 inch setup , i see no reason that why i can't modify the top part with the supply and return lines (which we can get i'm sure from dodge) and make my own 1/2" insert to replace this one for next to nothing . going to a larger line is a must for hi hp application .

[Mr.B]

If your fuel pressure gauge goes to zero at the end of the track then it sounds like you don't have enough fuel pump or your lines are to small.

On my old 67 Barracuda(Which belongs to TDR member Hiperf360now) i had to replace the only two mallory parts on the car within the first two months i had it. The Unilite distributer(if you have one of these burnit!) gave me hell for about a month before quitting all together. And the fuel pump(not sure which model) had the magnets come off of the can and stick to the armature. It may be just me but that kinda put a bad taste in my mouth about mallory. Theres my . 000002

Chad, You shouldn't need a regulator. The injector pump is internally regulated. If the 4140 is the same as the 4150 but with a regulator, there shouldn't be any reason why the 4150 wouldn't work. Probably cheaper too.

 

[sport bike]

A regulator is a waste of time. If your going to spend that much on a pump why don,t you spend a little more and get a great pump. Barry Grant BG220 HR fuel pump. It flows 220gph and pressure is set at 15psi. It is built for street use. Cost at Summit $239. Mallory $220. (140gph/12psi and does not have a built in bypass)The bypass helps to reduce the strain on the pump when max fueling is not required.

 

[Chad Sheets]

Thats something to think about with the BG. I searched my soul and could not find a reason for a regulator either. I think the Mallory guru tried to sell our friend something he didnt need.

 

[JB @ C and L Machine]

Sportbike... I posted many times the Holley was a POS and the mallory might be one step above that. Hope they listen to you better then they did me... JB

 

[Mopar-muscle]

yes Mr B , i know my fuel lines are to small and my pump is not up to the task at full throttle , especially being as far away from the pickup as it is .

i guess i'll have to look into the BG pump , may have to live with a carter replacement back at the tank for now , my BOMBing dollars are going into my superbee at the moment . #ad

 

[Chad Sheets]

I ordered the BG220. It is on its way. I will be thinking about mounting location. Could go stock, or back by the fuel tank. Its not like I am worried about noise with straight through exhaust anyway. I'll keep you guys posted on the instal as soon as I get it in.

 

[sport bike]

You wont believe your eyes when you open that box up!!!!!!!!!!THATS A REAL PUMP!!!!!!!

Can someone tell me the Summit web site address?
