Aeromotive Fuel Pressure Regulator Won't Adjust

Saturday, 6 July 2024

A wider range allows for adaptive pressure regulation, eliminating stalling of the engine or flooding of the cylinders. The pressure regulator body is corrosion resistant and can be used without the need for mounting. Also you should set your base pressure to 58 with the reference line removed. Engine Performance Level. This can cause the regulator to seem unable to be adjusted and it will create a pressure drop that looks like the pump is too small. In many cases, the regulator may be repaired, and older regulators may have to be replaced with a newer model. Got the new one, installed it and same issue.

I was hoping someone could conifrm with me that its a bad FPR. Best Fuel Pressure Regulator||Regulator Pressure||Body Material||Inlet/Outlet Ports||Buy Now|. I need a fuel system that can run high base fuel pressure between 70-120 PSI continuous. Nice to have for fine tuning. After installing a larger (or secondary) fuel pump for my EFI engine, the fuel rail pressure went up and my regulator won't adjust it back down, what's wrong? Standard ⅛ inch gauge port for pressure gauge. Pressure reading gauge for accurate readings. Although the load placed on the engine is measurable, running a mechanical pump at high pressure draws less than 2-3 horsepower, nothing compared to the power it helps the engine produce. The regulator can only regulate down to 7psi. Machined the rails and did a remote regulator (large size). No the 2003 ecotec fuel rail is different and can use an adjustable fpr, i am using the afc as well
. The brass plug is just held in by almost no tension at all, with white thread sealant. Killerbee oil pan and pickup. Location: TXVehicle: 2002 Bugeye.

Aeromotive Fuel Pressure Regulator Won't Adjust Pump

The stock gm or any manufacturers regulators have to hold pressure for so long. By discussing the above-mentioned factors, an ideal fuel pressure regulator can be bought. Nothing in the tune changed. That would be base fuel pressure and anything you read with the engine running is base +/- boost or vacuum. I bought this regulator because it goes down to 3psi. The last option is here to regulate the pressure on your pockets. If the return line or the regulator, or both, are too small for the pump, the resulting fuel pressure is said to be "false-high". I checked the fuses connected to the pump hardwires, both intact. Its an 03, but im pretty sure they are just using the FMU for the FPR because the line goes right off of the rail. So we got the car to fire up (this was the first time starting the motor too by the way) while my dads buddy messed with the timing and I messed with the regulator.

So if any debris came from that old hose it would probably be wedged in the primary injectors, but i drilled and tapped the stock primary rail to accept npt to -6 fittings. The guide will help you narrow down the best pressure regulator for you by covering all the important details. RJSPHH Fuel Pressure Regulator is a durable pressure regulator. I'm guessing both pumps are now dead. Fuel pressure seems to adjust fine and holds great when the engine is running, but when I shut the engine off, pressure drops quickly to zero.

The inner hose had rotted and was spraying fuel out of the braid. A good pressure regulation helps in enhancing performance as well as fuel efficiency. It has never leaked fuel and I have not had any issues with it, but I did use the correct fittings to prevent leaks. My setup is dual pumps with stainless lines feeding a rail. Finding an OEM fuel pressure regulator replacement of a recent motor might not be as challenging as our Dholaikhal has plenty in stock. After 93, the cars have a MAF and any change in pressure that results in change in a/f ratio would eventually be negated by the PCM using the O2 readings to modify fuel delivery. I might have to switch to an aeromotive. So for us 02 guys, even if the car isnt turbo, u could use the cartech FMU that isnt boost sensitive or any other FPR u wanted i guess. But the car won't start and I'm not getting any fuel pressure. Both the diaphram failed and leaked.

I had Amazon send a replacement pressure sensor for the AEM so we'll find out soon if its faulty or not. What Aeromotive regulator can I use, and is there an electric pump you would recommend? I get that you are looking for something to handle more volume but are you sure the volume killed the stocker or was it age or boost? I think we're using the one listed for a honda civic. What is the barb fitting in the regulator cap used for? 05-15-2014, 12:31 PM||# 25|. If so, how were the results? It's delivering gas, but starving when driving. Focusing on these factors, we have chosen our favorite pressure regulators: - Since the motorheads crave more and more performance, our first choice is the most powerful and high-pressure offering regulator. Durable body made of zinc alloy material.

Aeromotive Fuel Pressure Regulator Won't Adjust Kit

The regulator comes with a kit that includes a pressure gauge that gives accurate reading thanks to its slow needle movement. The high-performance engine needs a good fuel pump. 9/16 6AN||Check On Amazon|. Pressure regulation is achieved without interfering with the engine electronics. A fuel pressure regulator is a device that regulates the pressure of fuel. I find it odd they both crapped out without popping a fuse... Last edited by ALOKIN; 05-13-2014 at 12:51 AM. The pressure regulation of fuel has drastically improved engine performance and enhanced the automotive scene. Join Date: Oct 2001. You increase the pressure you throw everything off anyway thats in the tune. At Aeromotive we know our customers priority is to have the best possible flow and pressure control when the engine is running and we don t compromise this standard to force the regulator to seal when the engine is off.

It's all related to manifold pressure/vacuum. I cant get my FPR to set a base pressure of 40psi. Complete fuel system: -Walbro 255 in tank, which feeds the new Process West Surge Tank. Pros: - Supports high-capacity engines of up to 1000 HP.

The body of the regulator is made up of aluminum material which gives it a premium feel as well as stiffness. Depending on how freaked out i was i'd probably pull the pump and inspect the immersed soft line from the pump to the tank pass thru. What is the problem? Even installing a Walbro 255L/H fuel pump and/ or larger injectors does not require you to switch to an aftermarket FPR as the factory one will cope happily. This enhances the performance of an engine and helps maintain good fuel efficiency.

Usually on a cold startup (garage kept car) it will read 59-60psi. This is if you want 58 psi base pressure, if you want 65 psi or so its fine. No, it won't bolt right up. The new bypass regulator should be located in the engine compartment, as close to the fuel rail inlet as possible, and the return line will be the full length of the car. The regulator body is made up of aluminum with a built-in diaphragm. Testing for this problem is easy. Also ill say again your base pressure is too high. I hear the middle diaphragm also goes on some. But I found out when the car is not running the regulator won't go less than 7psi. Aeromotive EFI regulators P/SN 13101 and 13109 are popular for "returnless" engine transplants. If I mash the throttle for a second, it seems to respond and jumps to 60psi, and will climb a few psi as I build boost (2-4psi boost). Chapter/Region: Tri-State.

You could say two pumps "in parallel" will deliver twice the flow at any pressure, which can be very useful in systems with normal pressures that need substantial additional volume, but pumps in parallel at very high pressure, well zero times two is still zero. As a result, belt and hex drive fuel pumps can maintain high RPM at high pressure, making them perfect for high pressure, high flow applications. When I turn the key to on position the pressure builds to my preset on the FPR, then it drops to I wait just about 2 seconds before starting the car for this process to happen, and then start the car it runs fine. Nah it's not on yet
