ASR or Fuel Starvation? - Page 2 - ZR-1 Net Registry Forums

EDT · 04-09-2020

I changed the front filter as well (it turned into a true fiasco, I think I ended up pouring 3 gallons of fuel all over myself in the process), and when I’m feeling up for it I’ll go ahead and pull the assembly out and replace the stock plastic clamps to decent stainless pieces. As for the accordion piece, it runs great to redline in a straight line, but I’ll keep the knowledge in the back of my head. I haven’t had the opportunity to fill up and go for another run but I’ll update when I do. Thanks all

I bought a pair of "duck bill" Vise Grip pliers to pinch off the rubber hose at the tank B4 fussing with that filter. Just a thought for anyone considering changing that filter. (Mine @ 38k when I bought it was FULL of crap that spilled out in the catch pan.)

Also, make sure u unscrew the gas cap to equalize pressure. Same when working on injectors.

When I owned Barney, I changed the stock fuel filter several times and never spilled a drop of fuel.

First, I wouldn't do the change unless I had a quarter tank or less. Then I'd jack the front end up way high so the level of fuel was below the level of the filter. Then I'd, loosen the clamp and disconnect the rear connection. The front connection was always a bitch so I'd hold the front fitting with one wrench and break the filter loose with a bigger wrench on the hex on the back of the filter. The small amount of fuel spilled as the filter drained I'd catch in a small drain pan.

Installing the new filter was the reverse of above.

I’ve always started the car, then pulled the fuel pump fuse, loosened the fuel filler cap, and let it run a couple of minutes until it shut down. Uses up a great deal of fuel between the tank and the engine and drops the pressure in the lines. Makes changing the in line filter less messy. Haven’t ever had any trouble restarting the car, fuel pressure builds quickly when you turn the key to ACC before cracking her over.
