ok.... i have a 98 xj classic with the 4.0... the catch valve is ****ty n im loosin pressure if its sits for awhile.. im gonna change the whole assembly...pump,sending unit,etc,etc..

whats the best assembly for the $ ?? Bosch,Carter,etc,etc.... what seems to be the best brand to go with??

Thanks in advance!!

OEM would be the best.

Installation of fuel tank about 100' above roof will eliminate need for fuel pump and increase reliability.

I have had a LOT of experience with XJ fuel pumps. You are doing the right thing by installing a complete assembly.

Here are my preferences.

1. Bosch (yes, they are expensive but well worth the extra coin in reliability/longevity).
2. Carter
3. Refer to choices 1 and 2.

OEM is a great choice, but what they charge is ridiculous. Therefore, search for aftermarket Bosch or Carter.

I will not install, nor will I recommend Airtex. Don't even get me started on that. Search if you want to research it.

my choices are as listed above.. i was scared to call and get an oem price. lol
