Product Information & Review: LT4 Fuel Pump 

GPI is amazing. Just put in a huge order for my 5th gen Camaro. Everyone there is amazing. Parts are amazing.

Awesome video!

Is it a notable upgrade to the LT2 pump?

I have a PD3 cam from you guys in my 2018 ZL1 1LE, will this pump be a upgrade to my stock one? Thanks, also I have stainless works 2 inch long tubes, Katech oil pump upgrade, Katech 103 TB, 2.25 griptech upper, ATI with a 9.45 lower, Katech Ferra exhaust valves, Cadillac lifters with Brian Tooley and Smith Brothers trunnions, ported heads and supercharger with LMP 3gallon expansion tank. It ends out back with AWE 3 exhaust. Would be awesome if this pump could give me a little boost. I love the sound of your cam and the overall performance of it so far

How about the in tank pump? For my daily on e85 is it recommended? My in tank fuel pressure sensor went bad i was thinking about swapping while the tank is dropped.

switching from a lt1 pump and lt1 injectors … lt4 pump don’t put the lash cap right ? 2016 Camaro ss Btr L86 stage 2 cam / E-85/fully catless /tuned ..my lil set up lol
