2nd Gen Non-Engine/Transmission "HELP" regulator for fuel pressure gauge autometer.

Most any store that sells plumbing will also have 1/8" needle valves. They are common for ice makers and swamp coolers.

I have a seen the needle valves, just never seen a snubber before

I went through four senders in three months and gave up. Took Bills advice and went mechanical with a 1/8 inch needle valve. But instead of using 1/8" nylon hose I went with SS braided lines... . looks prettier.

Oops???? Sending Unit?

All this talk about sending units never lasting and needing a snubber... I just installed one(a sending unit, that is). It is a Westach. Will I have problems without using a snubber(valve)??

Five bucks is pretty cheap insurance that you won't

Sender mounted off the motor ? if not move sender to a mount off the motor and connect with a fuel line with a loop if you wan't to dampen the pulse . If you have sender on the motor you can and will have problems . Fuel line with brass fittings work fine and can be found at Home Depot or other store of this type. A damper can be made with a drilled orfice of about 2/32" put and banded in line to gauge . But with loop or long line the line will dampen the gauge needle or reading of a didgetal . LOL Ron in Louisville KYOo. Oo.

Ron,



That doesn't work with a P7100 pump. It will still hammer a mechanical gauge or pressure transducer for an electrical pump and break them. I installed a snubber. That helped. Then I installed a needle valve closed so that pressure came up slowly on my gauge. The setup that worked is needle valve in banjo fitting on the side of the pump, snubber, and a gease gun hose. The line to the mechanical gauge started there. Now there is a pressure transducer for my new pressure gauge. I'm hoping the trasducer will survive for a while since I really like my Westach 40 PSI gauge.

There doesn't seem to be a problem with the Westach sending units as there are with Auto-meter. In fact when I talked to AM about 4 months ago they said they were considering adding a label saying "Not for Diesel". Did they ever do this. Seems the best thing to do is fix the problem rather than to ignore it.

Had the same problem with my A/M senders. The tech guy told me they started using a different supplier / different sender.



The original ones (which lasted about a month - direct mounted to the filter housing) were silver/aluminum colored and were about 1&1/2-inch in diameter. The new ones are brass colored and about 3/4-inch in diameter.



The new ones are "supposed" to hold up better, but I use a needle valve and have them remote mounted now.



When I turn on the key it takes about 3 seconds for the needle to climb up to 13 psi.

 

[catoiler]

So much for the new senders from A/M,I have gone through 2 of them and it still does not work. As soon as the pressure gets around 15 lbs the gauge pegs and stays there. Am going to try a snubber and see if that works be for going to a mech gauge.

 

[Kyle]

Sorry about that

That's a shame. My pump never puts out more than 14 and the new senders have been in for over a year. Maybe there's no "headroom" on that sender -- they say 0 - 15 psi -- I guess they mean it.
