A couple days ago I posted a question about a fuel problem on my car in that when first cranked, the car would run fine bu after a couple of minutes the fuel pressure would begin to swing up and down, and eventually drop so low that the car would stall. At first I blamed the suction line to the pump, maybe being clogged, and then maybe the pump failing. Well today I ran the car will a hose in a gas can and it still had the same problem. So, I took the filler neck of the tank for a look inside and saw what looked like a piece of rubber stopping up the return line. So, I drained the tank, and took the line barb off, and presto. a completely plugged return line. Attached thumbnail(s) |

Another one. I also cut the end off that compresses down so that there is a full flow through the line. Inside the tank I also saw that the return hole is only 7/32'' (.219)dia. I drilled it out to 5/16'' dia. I put the tank back in the car, and put a gallon in it and now looking through the filler access hole with the car running, there is some serious agitation going on. The fuel pressure in now fully adjustable. Attached thumbnail(s) |
