[QUOTE="96dreamer, post: 16813956, member: 52560"] Anyone have issues with fuel temps and possible pump cavitation? A few weeks ago the car died and I had to push it to the side of the road and let it set for the afternoon. Luckily it was in my parent neighborhood right in front of someone's house. Ambient temp was 99° and the fuel temp got up to 115° when the fuel pressure started getting erratic before it stalled and wouldn't build pressure or idle. After sitting for a few hours I was able to get it to my parents house about a mile away. Let it sit over night and it drove home fine the next day. Fuel temp didn't seem to be an issue but it was only about 85° out and I drove it straight home. After that incident I ran the return line further from the pickup in the tank, I had it ran to inside the pickup area which was a mistake, and wrapped all of the fuel lines from the control arm mount back in heat insulation sleeve in addition to pulling the filters to check for restrictions. Both the pre and post filter looked great. Took it on a test drive last Friday when temps were about 90° ambient and although it took much longer the temps eventually got up to 115° again and it started having erratic fuel pressure again. I'm thinking the first time I had the issue it may have caused permanent damage to the pump which is now causing the issues to continue even though I believed I solved the initial issue. Currently debating sending the pump back to Fuelab The fuel system is a glenn's performance sleeper tank, fuelab 42401 pump with fuelab pre and post filters, -10 feed, fuelab regulator in the passenger fender feeding the rails deadhead and a -8 return from the regulator. I have the pump running via pwm from the MS3Pro . [ATTACH type="full"]1759756[/ATTACH] [/QUOTE]
