Raptor lift pump pressure drop question.
I just put a new raptor frame mounted 100 on my truck about 3 weeks ago.
The truck is stock with no mods done to it. Well... I set the fuel pressure at 18psi at idle and it can be consistantly drawn down to 13-15 psi. Now today when I got in it to start it it stayed at 15psi abd didnt come up until I had feathered the throttle alittle, it also Could be drawn down to 10psi...... I replaced my fuel filter a few minths ago so I wouldnt think that would be it. I have Glow shift gauges and my fp gauge is hooked to the IP with the snubber and sending unit on the inner fender. But I dont think its the gauge as it has done me well since installed. I guess my question is could the LP be weak? Most guys are saying they just pull down a few psi with their trucks. What do yall think? |
Double check with a mechanical test gauge. I have 2 gauges, one a glow shift electronic and an isspro mechanical. The glow shift is off by 2-5 psi.
---AutoMerged DoublePost--- I also forgot to mention to prefilter the raptor as they sieze due to any small debris in the fuel. I'm running a Vulcan performance vp max seperator, works great, reasonable and solved my problems. |
