what range is best to get? 0-15? 0-100?

Thanks James

 

0-15 covers the stock lift pump. 0-30 is better if you're going to step up to larger lines/pump, plus it puts the operating range into the middle of the gauge.

0-100 is just overkill for the low pressure side of the fuel system.

 

0-30 psi as a first choice, 0-15 psi as a second.

Forget about 0-100 psi - it does not have the resolution you need - I assume you are looking at Autometer?

Do yourself a favor and look at Isspro, Dipricol, or Stewart Warner.

There is tons of reading on this - just do a search in this forum

 

Yes, looking at Auto Meter to match the pyro and boost I have already. But the Auto meter Ultra-lites say not for use on a Ddge diesel. Anyone know why?

 

Possibly because the 0-15 psi range is borderline and its critical that it is installed correctly. Which guage is this? - mechanical or electric? If you do not install it correctly, pulsations from the fuel system can destroy the guage/sender in a matter of 10 minutes.

 

looking at this one.............http://store.summitracing.com/defaul...=egnsearch.asp

 

I called Autometer, and they do make a 0-30 psi ultralight gauge. It is P/N 4360. In order to use the autometer on a Dodge, you have to use a pressure snubber between the fuel pressure port and the sender. There is no part number for this item but if you call Autometer tech support and ask them for the pressure snubber, they will send you one for $10.00 shipped to the lower 48 states. The guy also told me that you need a stainless line kit, Autometer P/N 3227. It gets the sender off of the motor, isolating it from vibration, and allows you to mount the snubber between the motor & the sender. The gauge with the sender is about $225.00, snubber is $10.00, not sure on the line kit, but they are available from Summit as well. Hope this helps!!

 

Just looked up the line kit...$29.99 from Summit Racing
