accel dfi problem

[Jim Nilsen]

Just wanted to give an update..i rerouted the fuel lines and went with a single line going to the rails.that seemed to help but there was still a drop in pressure(not as bad though)..so i decided to drop the tank and take a look at the pickup..i found the strainer to be dirty..i ran air through it and it had quite a bit of restriction..so i think between the clogged strainer and the vapor lock issue i have found the problem.thanks again jim for your help...since now i have only one line running up to the rails do i need to increase fuel pressure? i have it set right now at 45psi...i know the ls1's run a higher pressure so i figured i ask..

Good to hear that it is better even with the restriction and even better with the filter clean.Set your pressure to what your program is set for, mine is at 45 psi. If your setup is programmed for more set it for what that value is. Fuel pressure is critical to getting the correct amount of fuel fer pulse as calculate in your VE table.

Do you have a wideband o2 and a gauge? they are getting more reasonable and are very usefull fo so many things involved.

Sounds like you are almost there !!!!
