I know a number of people don't use the factory Pollak valve unit.

Interested though for those that do run it (as part of standard factory set up) if anyone has experienced any issues with them and also good news stories of cars that are running with the valve unit without issue.

I still have fuel issues and am about to change the valve unit as one of the only parts I have not changed. This fixed a very similar issue for another car recently.

Hi,
I use the valve Pollak for many years. My engine is LS7 AS
710 HP.
I had one problem. Overheated fuel caused the jam. When I settled problems with the hot fuel valve is working perfectly. I rode 15.000 km and do not touch it. Any trouble but the fuel passes through the radiator.
Regards
Georg

Mine got clogged with baffling from the fuel tank, then cleared itself, then partially clogged itself again reducing flow causing overheating fuel if less than 1/2 tank of fuel. Had the car stall a few times.

I have since removed it, reworked the whole system, and run a linked fuel tank set up. All good now.

Did the valve unit fail when fuel was hot?

Would be interested in your radiator set up. How would that help in traffic with no airflow as that has been when my fuel has got hottest in the past.

Thanks for the reply.

Hi,
Jam valve was only once and then when the fuel was very hot. I was in Italy. the air temperature above 37 C. I have only one tank.
After returning home I bought summitracing fuel coolers, along with a fan and clamped over the reservoir. The engine hood made dust cover with carbon fiber. The air while driving hit a fuel cooler and if it is hot turn on the fan. In addition, I have installed two small fans / as in the Porsche / Exhaust hot air above the engine.
I race through different tracks and never had a problem with the valve and the hot fuel. Now I have a little demolished car after the season. I am every year in Italy, and no high temperatures did not interfere.
