I have the big line kit installed and its a great kit. But it also has the capabilities of hooking up a fuel pressure gauge. I was wondering does someone make a kit that will work with this? Whats the best way to hook this up. Thanks

 

for a 98 imo the best place it is in top of the fuel filter housing measureing fuel pressure on the output side. thats how i hooked up mine works great. i used a kit with a manual guage and a isolater. im not familiar with the big line kit so i cant help you there.

 

I too have the big line kit & the fitting on top of the filter that leads to the injection pump has a screw/pipe thread-- in the top of that fitting, you remove it & from there you plumb your line to your gauge

 

Geno's garage sells gauges and a kit to install to the filter housing.
