What gauge for AFPR?

[chicagoavenger]

Well I just bough an Aeromotive fpr and just wondering what gauge I should get. Also should it be liquid or not?

 

[blcknspo0ln]

Liquid filled is your best bet. Really, any gauge will do you right. Whether it be the b&m one or the marshall (the one I use) one.

Yea apparently liquid helps with vibrations and whatnot coming from the motor; Makes for a more accurate and reliable(long-living) gauge.

i have the one form summit

so this should work then correct since it will directly screw into any 1/8 NPT female port? thanks guys

Doesn't really matter which one you get, all automotive gauges are basically overpriced crap gauges . Go liquid filled for vibration resistance, just remember to pull the rubber plug every so often to vent the pressure the will build up inside the case. As for the link you gave, that gauge will do but it better to look for a gauge with more divisions. If you look at that one it only has 5 psi divisions, so its harder to set. Its better to get one that has 1 or 2 psi divisions.

good point. Does it matter if it's a 60psi or 100psi? I figure 36psi is base correct plus I run around maybe 15-20psi boost tops(depends on race gas or not). Isn't that 56psi the most I will see or it doesn't add up that way? 36psi base 20 psi=56psi

You are correct, every psi of boost will increase the fp 1 psi. As for your base setting, even though 37 psi is the normal base setting for a 1g man. (with vacuum line disconnected) I think some guys opt to increase the base to 43.5 psi (base 2g setting) so the injectors will flow what their rated at (since most injector companies rate their injectors at this pressure). Its probably best to go with the 100 psi gauge just to give you some room.

thank you for the info!!!
