Amrxuts Return Petrol Diesel Aluminium Review

looks like it holds the vacuum well. I use it on marine 2-stroke oil to stop backflow to the lower tank. Appears to show luminous flux time

I used it on a 1978 Fiat Spider. I needed a one way vapor valve from the gas tank and it worked great. I tested this with a vacuum and pressure gauge prior to installation. Works perfectly.

Appears to be made of good quality aluminum and has been working great for about a month. Installed it as a vacuum brake on the air line, which is probably not for the intended purpose, but it works. The shutter opens with very little pressure and the springs close under normal conditions. Slightly restrictive so flow can be reduced on a weaker pump, but not excessively. I will definitely be buying more of these for different projects.

Good block but slows flow due to the fact that although it is sold as a 1/2" OD check valve it actually measures 12mm as stated in the description . Unfortunately it's loose in the 1/2" tubing. You have to tighten the yoke fairly hard to seal it. The previous plastic check valve lasted several weeks and opened and closed 45 times a day, so I'm hoping this valve will last .I will update if this causes problems.

Installed this valve on my 1992 Jeep Yj 2.5L 4 Cyl. It ended up being installed on the fuel supply line because my jeep was having trouble starting due to the check valve in the fuel pump. I'm pretty sure it's all messed up, so this is a great alternative. I used a 5/16 fuel line and hose clamps to finish the job and my jeep now starts up quickly and easily with no starting issues every time. It will have a long start time after driving for a while and will stall or take a long time to start…
