My customer, the (blazer owner), took the the blazer to "LS tuner" and the tuner could not figure what was wrong with it. So I told him to bring it back and I would figure it out. Long story short, I finally figured it out. We had originally had custom lines fabbed up at a hydraulic/diesel shop and we first thought that the hose used was not fuel rated it was possibly collapsing. Turned out, the fuel pump that we had changed three times just wasn't supplying enough pressure under load. Originally we used an AIRTEX 3270 - the Oreilly brand of the A/C delco EP381. So, we went and purchased an A/C Delco EP381 and the blazer came alive.
For all that responded to my posts, Thank You!!!!!!!!!!!!!!!!!!!!!!!!!!
