with my install, i finally removed all the lpg stuff from the engine bay. now i have heaps of room on the passenger's side. i would like to put the air cleaner over there. if i use 3 inch pipe, will the length matter much ? would 2.5 inch be ok ? it would be simpler to get over the engine and under the bonnet. i don't think it will be a restriction, but you never know. read the air cleaner thread. i reckon i'll use some sort of truck air cleaner. and one of those restriction indicators. next question, can i use the barring tool to lock the engine ? i am trying to get the front pulley off for the kdp/case bolts deal. i have the relevant impact socket, but can't stop the motor from turning. an lastly, with the bottom hose fitting, is there an alternative that is around 2" diameter ? if i found one of those, i can probably use the old clevo bottom hose. making life real easy.
