Just remove the mechanical pump. They make a nice little aluminum cover that closes off the opening on top of the engine. As long as it is a low pressure pump like 2-3 psi area you should be fine.
Why run both? Wouldn't it make more sense to just let the electric pump run while whenever the key is on? I removed my mechanical pump and put in a low pressure K&N fuel pump and it seems to run just fine. Just my two pennies worth.
I believe if you can get a stock style one that has less cores you will be happier. I changed from a brass one in my 68 mustang to an aluminum one with 2 cores vs I believe 3 or 4 OEM and its is absolutely unbelievable the difference it makes. Was it aluminum ? I don't know but the less core is...
Guys what is the compressed and uncompressed length of the rear shocks on a 48 f1 truck? I want to order some but not 100% sure. Was going to order Monroe 32207 but want to make sure first. Thanks. Luke
